Anthropic’s Claude 3.5 Sonnet model now available in Amazon Bedrock: Even more intelligence than Claude 3 Opus at one-fifth the cost

Post Syndicated from Danilo Poccia original https://aws.amazon.com/blogs/aws/anthropics-claude-3-5-sonnet-model-now-available-in-amazon-bedrock-the-most-intelligent-claude-model-yet/

It’s been just 3 months since Anthropic launched Claude 3, a family of state-of-the-art artificial intelligence (AI) models that allows you to choose the right combination of intelligence, speed, and cost that suits your needs.

Today, Anthropic introduced Claude 3.5 Sonnet, its first release in the forthcoming Claude 3.5 model family. We are happy to announce that Claude 3.5 Sonnet is now available in Amazon Bedrock.

Claude 3.5 Sonnet raises the industry bar for intelligence, outperforming other generative AI models on a wide range of evaluations, including Anthropic’s previously most intelligent model, Claude 3 Opus. Claude 3.5 Sonnet is available with the speed and cost of the original Claude 3 Sonnet model. In fact, you can now get intelligence and speed better than Claude 3 Opus at one-fifth of the price because Claude 3.5 Sonnet is 80 percent cheaper than Opus.

Anthropic Claude 3.5 Sonnet Family

The frontier intelligence displayed by Claude 3.5 Sonnet combined with cost-effective pricing, makes the model ideal for complex tasks such as context-sensitive customer support, orchestrating multi-step workflows, and streamlining code translations.

Claude 3.5 Sonnet sets new industry benchmarks for undergraduate-level expert knowledge (MMLU), graduate-level expert reasoning (GPQA), code (HumanEval), and more. As you can see in the following table, according to Anthropic, Claude 3.5 Sonnet outperforms OpenAI’s GPT-4o and Google’s Gemini 1.5 Pro in nearly every benchmark.

Using Anthropic’s Claude 3.5 Sonnet in the Amazon Bedrock console
Because this is a new model, I go to the Amazon Bedrock console and choose Model access from the navigation pane to enable access to Claude 3.5 Sonnet.

Console screenshot.

Now that I have access to the model, I’d like to use it to extract information from the following image from the Our World in Data website:

Primary energy consumption from hydropower, 2022

I choose Chat in the Playgrounds section of the navigation pane and select Anthropic and Claude 3.5 Sonnet as the model. I then choose the Image upload button to upload the previous image, type the following prompt, and choose Run:

Which countries consume more than 1000 TWh from hydropower? Think step by step and look at all regions. Output in JSON.

Here’s the result and an animated image recapping what I did.

To determine which countries consume more than 1,000 TWh from hydropower in 2022, I need to carefully examine the map and color-coding. The scale at the bottom shows that dark blue represents consumption between 1,000 TWh and 2,000 TWh.

Let's look at each region systematically:

1. North America: Canada is dark blue, indicating it consumes between 1,000-2,000 TWh from hydropower.
2. South America: Brazil is dark blue, also consuming between 1,000-2,000 TWh.
3. Europe: No country is dark blue; all are light green or have no data.
4. Africa: No data available for any country.
5. Asia: China is dark blue, indicating consumption between 1,000-2,000 TWh.
6. Oceania: No country is dark blue; Australia is light green.

In summary, there are three countries that consume more than 1,000 TWh from hydropower in 2022:
1. Canada (North America)
2. Brazil (South America)
3. China (Asia)

Here's the response in JSON format:

```json
{
  "countries_consuming_over_1000TWh_hydropower": [
    {
      "name": "Canada",
      "region": "North America",
      "consumption_range": "1,000-2,000 TWh"
    },
    {
      "name": "Brazil",
      "region": "South America",
      "consumption_range": "1,000-2,000 TWh"
    },
    {
      "name": "China",
      "region": "Asia",
      "consumption_range": "1,000-2,000 TWh"
    }
  ]
}
```

These three countries stand out as the highest consumers of hydropower energy, each using between 1,000 and 2,000 terawatt-hours in 2022.

Anthropic's Claude 3.5 Sonnet demo in the Amazon Bedrock console.

The model’s ability to reliably extract information from unstructured data, like images, opens up a world of new possibilities.

I choose the three small dots in the corner of the playground window and then View API request to see code examples using the model in the AWS Command Line Interface (AWS CLI) and AWS SDKs. Let’s have a better look at the code syntax.

Using Claude 3.5 Sonnet with AWS SDKs
You can use Claude 3.5 Sonnet with any AWS SDK using the new Amazon Bedrock Converse API or Anthropic Claude Messages API.

To update code already using a Claude 3 model, I just need to replace the model ID with:

anthropic.claude-3-5-sonnet-20240620-v1:0

Here’s a sample implementation with the AWS SDK for Python (Boto3) using the same image as before to show how to use images and text with the Converse API.

import boto3
from botocore.exceptions import ClientError

MODEL_ID = "anthropic.claude-3-5-sonnet-20240620-v1:0"

IMAGE_NAME = "primary-energy-hydro.png"

bedrock_runtime = boto3.client("bedrock-runtime", region_name="us-east-1")

with open(IMAGE_NAME, "rb") as f:
    image = f.read()

user_message = "Which countries consume more than 1000 TWh from hydropower? Think step by step and look at all regions. Output in JSON."

messages = [
    {
        "role": "user",
        "content": [
            {"image": {"format": "png", "source": {"bytes": image}}},
            {"text": user_message},
        ],
    }
]

response = bedrock_runtime.converse(
    modelId=MODEL_ID,
    messages=messages,
)
response_text = response["output"]["message"]["content"][0]["text"]
print(response_text)

When I run it, I get a similar output as in the console:

Let's approach this step-by-step:

1. First, I'll examine the color scale at the bottom of the map. The darkest blue color represents consumption of 2,000 TWh or more.

2. Now, I'll scan the map region by region:

   North America: Canada is dark blue, indicating over 1,000 TWh.
   South America: Brazil is also dark blue, over 1,000 TWh.
   Europe: No country appears to be dark blue.
   Africa: No country appears to be dark blue.
   Asia: China stands out as dark blue, indicating over 1,000 TWh.
   Oceania: No country appears to be dark blue.

3. To be thorough, I'll double-check for any medium blue countries that might be close to or over 1,000 TWh, but I don't see any that appear to reach that threshold.

4. Based on this analysis, there are three countries that clearly consume more than 1,000 TWh from hydropower.

Now, I'll format the answer in JSON:

```json
{
  "countries_consuming_over_1000TWh_hydropower": [
    "Canada",
    "Brazil",
    "China"
  ]
}
```

This JSON output lists the three countries that visually appear to consume more than 1,000 TWh of primary energy from hydropower according to the 2022 data presented in the map.

Because I didn’t specify a JSON syntax, the two answers use a different format. In your applications, you can describe in the prompt the JSON properties you want or provide a sample to get a standard format in output.

For more examples, see the code samples in the Amazon Bedrock User Guide. For a more advanced use case, here’s a fully functional tool use demo illustrating how to connect a generative AI model with a custom tool or API.

Using Claude 3.5 Sonnet with the AWS CLI
There are times when nothing beats the speed of the command line. This is how you can use the AWS CLI with the new model:

aws bedrock-runtime converse \
    --model-id anthropic.claude-3-5-sonnet-20240620-v1:0 \
    --messages '{"role": "user", "content": [{"text": "Alice has N brothers and she also has M sisters. How many sisters does Alice’s brother have?"}]}' \
    --region us-east-1
    --query output.message.content

In the output, I use the query option to only get the content of the output message:

[
    {
        "text": "Let's approach this step-by-step:\n\n1. First, we need to understand the relationships:\n   - Alice has N brothers\n   - Alice has M sisters\n\n2. Now, let's consider Alice's brother:\n   - He is one of Alice's N brothers\n   - He has the same parents as Alice\n\n3. This means that Alice's brother has:\n   - The same sisters as Alice\n   - One sister more than Alice (because Alice herself is his sister)\n\n4. Therefore, the number of sisters Alice's brother has is:\n   M + 1\n\n   Where M is the number of sisters Alice has.\n\nSo, the answer is: Alice's brother has M + 1 sisters."
    }
]

I copy the text into a small Python program to see it printed on multiple lines:

print("Let's approach this step-by-step:\n\n1. First, we need to understand the relationships:\n   - Alice has N brothers\n   - Alice has M sisters\n\n2. Now, let's consider Alice's brother:\n   - He is one of Alice's N brothers\n   - He has the same parents as Alice\n\n3. This means that Alice's brother has:\n   - The same sisters as Alice\n   - One sister more than Alice (because Alice herself is his sister)\n\n4. Therefore, the number of sisters Alice's brother has is:\n   M + 1\n\n   Where M is the number of sisters Alice has.\n\nSo, the answer is: Alice's brother has M + 1 sisters.")
Let's approach this step-by-step:

1. First, we need to understand the relationships:
   - Alice has N brothers
   - Alice has M sisters

2. Now, let's consider Alice's brother:
   - He is one of Alice's N brothers
   - He has the same parents as Alice

3. This means that Alice's brother has:
   - The same sisters as Alice
   - One sister more than Alice (because Alice herself is his sister)

4. Therefore, the number of sisters Alice's brother has is:
   M + 1

   Where M is the number of sisters Alice has.

So, the answer is: Alice's brother has M + 1 sisters.

Even if this was a quite nuanced question, Claude 3.5 Sonnet got it right and described its reasoning step by step.

Build a decentralized semantic search engine on heterogeneous data stores using autonomous agents

Post Syndicated from Dhaval Shah original https://aws.amazon.com/blogs/big-data/build-a-decentralized-semantic-search-engine-on-heterogeneous-data-stores-using-autonomous-agents/

Large language models (LLMs) such as Anthropic Claude and Amazon Titan have the potential to drive automation across various business processes by processing both structured and unstructured data. For example, financial analysts currently have to manually read and summarize lengthy regulatory filings and earnings transcripts in order to respond to Q&A on investment strategies. LLMs could automate the extraction and summarization of key information from these documents, enabling analysts to query the LLM and receive reliable summaries. This would allow analysts to process the documents to develop investment recommendations faster and more efficiently. Anthropic Claude and other LLMs on Amazon Bedrock can bring new levels of automation and insight across many business functions that involve both human expertise and access to knowledge spread across an organization’s databases and content repositories.

Amazon Bedrock is a fully managed service that offers a choice of high-performing foundation models (FMs) from leading AI companies like AI21 Labs, Anthropic, Cohere, Meta, Stability AI, and Amazon via a single API, along with a broad set of capabilities you need to build generative AI applications with security, privacy, and responsible AI.

In this post, we show how to build a Q&A bot with RAG (Retrieval Augmented Generation). RAG uses data sources like Amazon Redshift and Amazon OpenSearch Service to retrieve documents that augment the LLM prompt. For getting data from Amazon Redshift, we use the Anthropic Claude 2.0 on Amazon Bedrock, summarizing the final response based on pre-defined prompt template libraries from LangChain. To get data from Amazon OpenSearch Service, we chunk, and convert the source data chunks to vectors using Amazon Titan Text Embeddings model.

For client interaction we use Agent Tools based on ReAct. A ReAct prompt consists of few-shot task-solving trajectories, with human-written text reasoning traces and actions, as well as environment observations in response to actions. In this example, we use ReAct for zero-shot training to generate responses to fit in a pre-defined template. The additional information is concatenated as context with the original input prompt and fed to the text generator which produces the final output. This makes RAG adaptive for situations where facts could evolve over time.

Solution overview

Our solution demonstrates how financial analysts can use generative artificial intelligence (AI) to adapt their investment recommendations based on financial reports and earnings transcripts with RAG to use LLMs to generate factual content.

The hybrid architecture uses multiple databases and LLMs, with foundation models from Amazon Bedrock for data source identification, SQL generation, and text generation with results. In the following architecture, Steps 1 and 2 represent data ingestion to be done by data engineering in batch mode. Steps 3, 4, and 5 are the queries and response formation.

The following diagram shows a more detailed view of the Q&A processing chain. The user asks a question, and LangChain queries the Redshift and OpenSearch Service data stores for relevant information to build the prompt. It sends the prompt to the Anthropic Claude on Amazon Bedrock model, and returns the response.

The details of each step are as follows:

  1. Populate the Amazon Redshift Serverless data warehouse with company stock information stored in Amazon Simple Storage Service (Amazon S3). Redshift Serverless is a fully functional data warehouse holding data tables maintained in real time.
  2. Load the unstructured data from your S3 data lake to OpenSearch Service to create an index to store and perform semantic search. The LangChain library loads knowledge base documents, splits the documents into smaller chunks, and uses Amazon Titan to generate embeddings for chunks.
  3. The client submits a question via an interface like a chatbot or website.
  4. You will create multiple steps to transform a user query passed from Amazon SageMaker Notebook to execute API calls to LLMs from Amazon Bedrock. Use LLM-based Agents to generate SQL from Text and then validate if query is relevant to data warehouse tables. If yes, run query to extract information. The LangChain library calls Amazon Titan embeddings to generate a vector for the user’s question. It calls OpenSearch vector search to get similar documents.
  5. LangChain calls Anthropic Claude on Amazon Bedrock model with the additional, retrieved knowledge as context, to generate an answer for the question. It returns generated content to client

In this deployment, you will choose Amazon Redshift Serverless, use Anthropic Claude 2.0  model on Amazon Bedrock and Amazon Titan Text Embeddings model. Overall spend for the deployment will be directly proportional to number of input/output tokens for Amazon Bedrock models, Knowledge base volume, usage hours and so on.

To deploy the solution, you need two datasets: SEC Edgar Annual Financial Filings and Stock pricing data. To join these datasets for analysis, you need to choose Stock Symbol as the join key. The provided AWS CloudFormation template deploys the datasets required for this post, along with the SageMaker notebook.

Prerequisites

To follow along with this post, you should have an AWS account with AWS Identity and Access Management (IAM) user credentials to deploy AWS services.

Deploy the chat application using AWS CloudFormation

To deploy the resources, complete the following steps:

  1. Deploy the following CloudFormation template to create your stack in the us-east-1 AWS Region.The stack will deploy an OpenSearch Service domain, Redshift Serverless endpoint, SageMaker notebook, and other services like VPC and IAM roles that you will use in this post. The template sets a default user name password for the OpenSearch Service domain, and sets up a Redshift Serverless admin. You can choose to modify them or use the default values.
  2. On the AWS CloudFormation console, navigate to the stack you created.
  3. On the Outputs tab, choose the URL for SageMakerNotebookURL to open the notebook.
  4. In Jupyter, choose semantic-search-with-amazon-opensearch, thenblog, then the LLM-Based-Agentfolder.
  5. Open the notebook Generative AI with LLM based autonomous agents augmented with structured and unstructured data.ipynb.
  6. Follow the instructions in the notebook and run the code sequentially.

Run the notebook

There are six major sections in the notebook:

  • Prepare the unstructured data in OpenSearch Service – Download the SEC Edgar Annual Financial Filings dataset and convert the company financial filing document into vectors with Amazon Titan Text Embeddings model and store the vector in an Amazon OpenSearch Service vector database.
  • Prepare the structured data in a Redshift database – Ingest the structured data into your Amazon Redshift Serverless table.
  • Query the unstructured data in OpenSearch Service with a vector search – Create a function to implement semantic search with OpenSearch Service. In OpenSearch Service, match the relevant company financial information to be used as context information to LLM. This is unstructured data augmentation to the LLM.
  • Query the structured data in Amazon Redshift with SQLDatabaseChain – Use the LangChain library LLM text to SQL to query company stock information stored in Amazon Redshift. The search result will be used as context information to the LLM.
  • Create an LLM-based ReAct agent augmented with data in OpenSearch Service and Amazon Redshift – Use the LangChain library to define a ReAct agent to judge whether the user query is stock- or investment-related. If the query is stock related, the agent will query the structured data in Amazon Redshift to get the stock symbol and stock price to augment context to the LLM. The agent also uses semantic search to retrieve relevant financial information from OpenSearch Service to augment context to the LLM.
  • Use the LLM-based agent to generate a final response based on the template used for zero-shot training – The following is a sample user flow for a stock price recommendation for the query, “Is ABC a good investment choice right now.”

Example questions and responses

In this section, we show three example questions and responses to test our chatbot.

Example 1: Historical data is available

In our first test, we explore how the bot responds to a question when historical data is available. We use the question, “Is [Company Name] a good investment choice right now?” Replace [Company Name] with a company you want to query.

This is a stock-related question. The company stock information is in Amazon Redshift and the financial statement information is in OpenSearch Service. The agent will run the following process:

  1. Determine if this is a stock-related question.
  2. Get the company name.
  3. Get the stock symbol from Amazon Redshift.
  4. Get the stock price from Amazon Redshift.
  5. Use semantic search to get related information from 10k financial filing data from OpenSearch Service.
response = zero_shot_agent("\n\nHuman: Is {company name} a good investment choice right now? \n\nAssistant:")

The output may look like the following:

Final Answer: Yes, {company name} appears to be a good investment choice right now based on the stable stock price, continued revenue and earnings growth, and dividend payments. I would recommend investing in {company name} stock at current levels.

You can view the final response from the complete chain in your notebook.

Example 2: Historical data is not available

In this next test, we see how the bot responds to a question when historical data is not available. We ask the question, “Is Amazon a good investment choice right now?”

This is a stock-related question. However, there is no Amazon stock price information in the Redshift table. Therefore, the bot will answer “I cannot provide stock analysis without stock price information.” The agent will run the following process:

  1. Determine if this is a stock-related question.
  2. Get the company name.
  3. Get the stock symbol from Amazon Redshift.
  4. Get the stock price from Amazon Redshift.
response = zero_shot_agent("\n\nHuman: Is Amazon a good investment choice right now? \n\nAssistant:")

The output looks like the following:

Final Answer: I cannot provide stock analysis without stock price information.

Example 3: Unrelated question and historical data is not available

For our third test, we see how the bot responds to an irrelevant question when historical data is not available. This is testing for hallucination. We use the question, “What is SageMaker?”

This is not a stock-related query. The agent will run the following process:

  1. Determine if this is a stock-related question.
response = zero_shot_agent("\n\nHuman: What is SageMaker? \n\nAssistant:")

The output looks like the following:

Final Answer: What is SageMaker? is not a stock related query.

This was a simple RAG-based ReAct chat agent analyzing the corpus from different data stores. In a realistic scenario, you might choose to further enhance the response with restrictions or guardrails for input and output like filtering harsh words for robust input sanitization, output filtering, conversational flow control, and more. You may also want to explore the programmable guardrails to LLM-based conversational systems.

Clean up

To clean up your resources, delete the CloudFormation stack llm-based-agent.

Conclusion

In this post, you explored how LLMs play a part in answering user questions. You looked at a scenario for helping financial analysts. You could employ this methodology for other Q&A scenarios, like supporting insurance use cases, by quickly contextualizing claims data or customer interactions. You used a knowledge base of structured and unstructured data in a RAG approach, merging the data to create intelligent chatbots. You also learned how to use autonomous agents to help provide responses that are contextual and relevant to the customer data and limit irrelevant and inaccurate responses.

Optimized for low-latency workloads, Mistral Small now available in Amazon Bedrock

Post Syndicated from Esra Kayabali original https://aws.amazon.com/blogs/aws/optimized-for-low-latency-workloads-mistral-small-now-available-in-amazon-bedrock/

Today, I am happy to announce that the Mistral Small foundation model (FM) from Mistral AI is now generally available in Amazon Bedrock. This a fast-follow to our recent announcements of Mistral 7B and Mixtral 8x7B in March, and Mistral Large in April. You can now access four high-performing models from Mistral AI in Amazon Bedrock including Mistral Small, Mistral Large, Mistral 7B, and Mixtral 8x7B, further expanding model choice.

Mistral Small, developed by Mistral AI, is a highly efficient large language model (LLM) optimized for high-volume, low-latency language-based tasks. Mistral Small is perfectly suited for straightforward tasks that can be performed in bulk, such as classification, customer support, or text generation. It provides outstanding performance at a cost-effective price point.

Some key features of Mistral Small you need to know about:

  • Retrieval-Augmented Generation (RAG) specialization – Mistral Small ensures that important information is retained even in long context windows, which can extend up to 32K tokens.
  • Coding proficiency – Mistral Small excels in code generation, review, and commenting, supporting major coding languages.
  • Multilingual capability – Mistral Small delivers top-tier performance in French, German, Spanish, and Italian, in addition to English. It also supports dozens of other languages.

Getting started with Mistral Small
I first need access to the model to get started with Mistral Small. I go to the Amazon Bedrock console, choose Model access, and then choose Manage model access. I expand the Mistral AI section, choose Mistral Small, and then choose Save changes.

I now have model access to Mistral Small, and I can start using it in Amazon Bedrock. I refresh the Base models table to view the current status.

I use the following template to build a prompt for the model to get sub-optimal outputs:

<s>[INST] Instruction [/INST]

Note that <s> is a special token for beginning of string (BOS) while [INST] and [/INST] are regular strings.

I try the following prompt to see a classification example:

Prompt:

<s>[INST] Classify the following email to determine if it is spam or not. Only respond with the exact words "Spam" or "Not spam".
🎉 Limited time offer! Buy 2, Get 1 Free! Offer ends today! Don't miss out the CHANCE TO SAVE, please click on the link below: https://bit.ly/buy-2-get-1-free [/INST]

Mistral 7B, Mixtral 8x7B, and Mistral Large can all correctly classify this email as “Spam.” Mistral Small is also able to classify this accurately, just as the larger models can. I also try several similar tasks, such as generating a Bash script from a text prompt and generating a recipe to prepare yoghurt, and get good results. For this reason, Mistral Small is the most cost-effective and efficient option of the Mistral AI models in Amazon Bedrock for such tasks.

Mistral Small excels in multilingual tasks. Along with English, it delivers superior performance in French, German, Spanish, and Italian. I test the model’s understanding of the German language by asking it to give me two sentences about sustainability:

Prompt:

<s>[INST] Geben Sie mir zwei Sätze zum Thema Nachhaltigkeit. [/INST]

Output:

1. Nachhaltigkeit bedeutet, die Bedürfnisse der heutigen Generation zu befriedigen, ohne die Möglichkeiten künftiger Generationen zu gefährden.
2. Ein nachhaltiger Lebensstil umfasst den bewussten Umgang mit Ressourcen, wie Wasser, Energie und Rohstoffen, sowie den Schutz von Umwelt und Klima.
Diese Sätze sollten Ihnen einen guten Überblick über das Thema Nachhaltigkeit geben.

Programmatically interact with Mistral Small
I can use AWS Command Line Interface (AWS CLI) and AWS Software Development Kit (SDK) to programmatically interact with Mistral Small using Amazon Bedrock APIs. I use the following code in Python, which interacts with Amazon Bedrock Runtime APIs with AWS SDK, asking, “What is the color of the sky?”:

import argparse
import boto3
from botocore.exceptions import ClientError
import json

accept = "application/json"
content_type = "application/json"

def invoke_model(model_id, input_data, region, streaming): 
  client = boto3.client('bedrock-runtime', region_name=region)
  try:
    if streaming:
      response = client.invoke_model_with_response_stream(body=input_data, modelId=model_id, accept=accept, contentType=content_type)
    else:
      response = client.invoke_model(body=input_data, modelId=model_id, accept=accept, contentType=content_type)
    status_code = response['ResponseMetadata']['HTTPStatusCode']
    print(json.loads(response.get('body').read()))
  except ClientError as e:
    print(e)

if __name__ == "__main__":
  parser = argparse.ArgumentParser(description="Bedrock Testing Tool")
  parser.add_argument("--prompt", type=str, help="prompt to use", default="Hello")
  parser.add_argument("--max-tokens", type=int, default=64)
  parser.add_argument("--streaming", choices=["true", "false"], help="whether to stream or not", default="false")
  args = parser.parse_args()
  streaming = False
  if args.streaming == "true":
    streaming = True
  input_data = json.dumps({
    "prompt": f"<s>[INST]{args.prompt}[/INST]",
    "max_tokens": args.max_tokens
  })
  invoke_model(model_id="mistral.mistral-small-2402-v1:0", input_data=input_data, region="us-east-1", streaming=streaming)

I get the following output:

{'outputs': [{'text': ' The color of the sky can vary depending on the time of day, weather,', 'stop_reason': 'length'}]}

Now available
The Mistral Small model is now available in Amazon Bedrock in the US East (N. Virginia) Region.

We already see customers exploring Titan Text Premier to implement interactive AI assistants that create summaries from unstructured data such as emails. They’re also exploring the model to extract relevant information across company systems and data sources to create more meaningful product summaries.

Here’s a demo video created by my colleague Brooke Jamieson that shows an example of how you can put Titan Text Premier to work for your business.

Custom fine-tuning of Amazon Titan Text Premier (preview) – You can fine-tune Titan Text Premier with your own data in Amazon Bedrock to increase model accuracy by providing your own task-specific labeled training dataset. Customizing Titan Text Premier helps to further specialize your model and create unique user experiences that reflect your company’s brand, style, voice, and services.

Built responsibly – Amazon Titan Text Premier incorporates safe, secure, and trustworthy practices. The AWS AI Service Card for Amazon Titan Text Premier documents the model’s performance across key responsible AI benchmarks from safety and fairness to veracity and robustness. The model also integrates with Guardrails for Amazon Bedrock so you can implement additional safeguards customized to your application requirements and responsible AI policies. Amazon indemnifies customers who responsibly use Amazon Titan models against claims that generally available Amazon Titan models or their outputs infringe on third-party copyrights.

Amazon Titan Text Premier model performance
Titan Text Premier has been built to deliver broad intelligence and utility relevant for enterprises. The following table shows evaluation results on public benchmarks that assess critical capabilities, such as instruction following, reading comprehension, and multistep reasoning against price-comparable models. The strong performance across these diverse and challenging benchmarks highlights that Titan Text Premier is built to handle a wide range of use cases in enterprise applications, offering great price performance. For all benchmarks listed below, a higher score is a better score.

Note: Benchmarks evaluate model performance using a variation of few-shot and zero-shot prompting. With few-shot prompting, you provide the model with a number of concrete examples (three for 3-shot, five for 5-shot, etc.) of how to solve a specific task. This demonstrates the model’s ability to learn from example, called in-context learning. With zero-shot prompting on the other hand, you evaluate a model’s ability to perform tasks by relying only on its preexisting knowledge and general language understanding without providing any examples.

Get started with Amazon Titan Text Premier
To enable access to Amazon Titan Text Premier, navigate to the Amazon Bedrock console and choose Model access on the bottom left pane. On the Model access overview page, choose the Manage model access button in the upper right corner and enable access to Amazon Titan Text Premier.

Select Amazon Titan Text Premier in Amazon Bedrock model access page

To use Amazon Titan Text Premier in the Bedrock console, choose Text or Chat under Playgrounds in the left menu pane. Then choose Select model and select Amazon as the category and Titan Text Premier as the model. To explore the model, you can load examples. The following screenshot shows one of those examples that demonstrates the model’s chain of thought (CoT) and reasoning capabilities.

Amazon Titan Text Premier in the Amazon Bedrock chat playground

By choosing View API request, you can get a code example of how to invoke the model using the AWS Command Line Interface (AWS CLI) with the current example prompt. You can also access Amazon Bedrock and available models using the AWS SDKs. In the following example, I will use the AWS SDK for Python (Boto3).

Amazon Titan Text Premier in action
For this demo, I ask Amazon Titan Text Premier to summarize one of my previous AWS News Blog posts that announced the availability of Amazon Titan Image Generator and the watermark detection feature.

For summarization tasks, a recommended prompt template looks like this:

The following is text from a {{Text Category}}:
{{Text}}
Summarize the {{Text Category}} in {{length of summary}}

For more prompting best practices, check out the Amazon Titan Text Prompt Engineering Guidelines.

I adapt this template to my example and define the prompt. In preparation, I saved my News Blog post as a text file and read it into the post string variable.

prompt = """
The following is text from a AWS News Blog post:

<text>
%s
</text>

Summarize the above AWS News Blog post in a short paragraph.

Similar to previous Amazon Titan Text models, Amazon Titan Text Premier supports temperature and topP inference parameters to control the randomness and diversity of the response, as well as maxTokenCount and stopSequences to control the length of the response.

import boto3
import json

bedrock_runtime = boto3.client(service_name="bedrock-runtime")

body = json.dumps({
    "inputText": prompt, 
    "textGenerationConfig":{  
        "maxTokenCount":256,
        "stopSequences":[],
        "temperature":0,
        "topP":0.9
    }
})

Then, I use the InvokeModel API to send the inference request.

response = bedrock_runtime.invoke_model(
    body=body,
	modelId="amazon.titan-text-premier-v1:0",
    accept="application/json", 
    contentType="application/json"
)

response_body = json.loads(response.get('body').read())
print(response_body.get('results')[0].get('outputText'))

And here’s the response:

Amazon Titan Image Generator is now generally available in Amazon Bedrock, giving you an easy way to build and scale generative AI applications with new image generation and image editing capabilities, including instant customization of images. Watermark detection for Titan Image Generator is now generally available in the Amazon Bedrock console.

Build generative AI applications with Amazon Bedrock Studio (preview)

Post Syndicated from Antje Barth original https://aws.amazon.com/blogs/aws/build-generative-ai-applications-with-amazon-bedrock-studio-preview/

Today, we’re introducing Amazon Bedrock Studio, a new web-based generative artificial intelligence (generative AI) development experience, in public preview. Amazon Bedrock Studio accelerates the development of generative AI applications by providing a rapid prototyping environment with key Amazon Bedrock features, including Knowledge Bases, Agents, and Guardrails.

As a developer, you can now use your company’s single sign-on credentials to sign in to Bedrock Studio and start experimenting. You can build applications using a wide array of top performing models, evaluate, and share your generative AI apps within Bedrock Studio. The user interface guides you through various steps to help improve a model’s responses. You can experiment with model settings, and securely integrate your company data sources, tools, and APIs, and set guardrails. You can collaborate with team members to ideate, experiment, and refine your generative AI applications—all without requiring advanced machine learning (ML) expertise or AWS Management Console access.

As an Amazon Web Services (AWS) administrator, you can be confident that developers will only have access to the features provided by Bedrock Studio, and won’t have broader access to AWS infrastructure and services.

Amazon Bedrock Studio

Now, let me show you how to get started with Amazon Bedrock Studio.

Get started with Amazon Bedrock Studio
As an AWS administrator, you first need to create an Amazon Bedrock Studio workspace, then select and add users you want to give access to the workspace. Once the workspace is created, you can share the workspace URL with the respective users. Users with access privileges can sign in to the workspace using single sign-on, create projects within their workspace, and start building generative AI applications.

Create Amazon Bedrock Studio workspace
Navigate to the Amazon Bedrock console and choose Bedrock Studio on the bottom left pane.

Amazon Bedrock Studio in the Bedrock console

Before creating a workspace, you need to configure and secure the single sign-on integration with your identity provider (IdP) using the AWS IAM Identity Center. For detailed instructions on how to configure various IdPs, such as AWS Directory Service for Microsoft Active Directory, Microsoft Entra ID, or Okta, check out the AWS IAM Identity Center User Guide. For this demo, I configured user access with the default IAM Identity Center directory.

Next, choose Create workspace, enter your workspace details, and create any required AWS Identity and Access Management (IAM) roles.

If you want, you can also select default generative AI models and embedding models for the workspace. Once you’re done, choose Create.

Next, select the created workspace.

Amazon Bedrock Studio, workspace created

Then, choose User management and Add users or groups to select the users you want to give access to this workspace.

Add users to your Amazon Bedrock Studio workspace

Back in the Overview tab, you can now copy the Bedrock Studio URL and share it with your users.

Amazon Bedrock Studio, share workspace URL

Build generative AI applications using Amazon Bedrock Studio
As a builder, you can now navigate to the provided Bedrock Studio URL and sign in with your single sign-on user credentials. Welcome to Amazon Bedrock Studio! Let me show you how to choose from industry leading FMs, bring your own data, use functions to make API calls, and safeguard your applications using guardrails.

Choose from multiple industry leading FMs
By choosing Explore, you can start selecting available FMs and explore the models using natural language prompts.

Amazon Bedrock Studio UI

If you choose Build, you can start building generative AI applications in a playground mode, experiment with model configurations, iterate on system prompts to define the behavior of your application, and prototype new features.

Amazon Bedrock Studio - start building applications

Bring your own data
With Bedrock Studio, you can securely bring your own data to customize your application by providing a single file or by selecting a knowledge base created in Amazon Bedrock.

Amazon Bedrock Studio - start building applications

Use functions to make API calls and make model responses more relevant
A function call allows the FM to dynamically access and incorporate external data or capabilities when responding to a prompt. The model determines which function it needs to call based on an OpenAPI schema that you provide.

Functions enable a model to include information in its response that it doesn’t have direct access to or prior knowledge of. For example, a function could allow the model to retrieve and include the current weather conditions in its response, even though the model itself doesn’t have that information stored.

Amazon Bedrock Studio - Add functions

Safeguard your applications using Guardrails for Amazon Bedrock
You can create guardrails to promote safe interactions between users and your generative AI applications by implementing safeguards customized to your use cases and responsible AI policies.

Amazon Bedrock Studio - Add Guardrails

When you create applications in Amazon Bedrock Studio, the corresponding managed resources such as knowledge bases, agents, and guardrails are automatically deployed in your AWS account. You can use the Amazon Bedrock API to access those resources in downstream applications.

Here’s a short demo video of Amazon Bedrock Studio created by my colleague Banjo Obayomi.

Join the preview
Amazon Bedrock Studio is available today in public preview in AWS Regions US East (N. Virginia) and US West (Oregon). To learn more, visit the Amazon Bedrock Studio page and User Guide.

Give Amazon Bedrock Studio a try today and let us know what you think! Send feedback to AWS re:Post for Amazon Bedrock or through your usual AWS contacts, and engage with the generative AI builder community at community.aws.

Build RAG applications with MongoDB Atlas, now available in Knowledge Bases for Amazon Bedrock

Post Syndicated from Abhishek Gupta original https://aws.amazon.com/blogs/aws/build-rag-applications-with-mongodb-atlas-now-available-in-knowledge-bases-for-amazon-bedrock/

Foundational models (FMs) are trained on large volumes of data and use billions of parameters. However, in order to answer customers’ questions related to domain-specific private data, they need to reference an authoritative knowledge base outside of the model’s training data sources. This is commonly achieved using a technique known as Retrieval Augmented Generation (RAG). By fetching data from the organization’s internal or proprietary sources, RAG extends the capabilities of FMs to specific domains, without needing to retrain the model. It is a cost-effective approach to improving model output so it remains relevant, accurate, and useful in various contexts.

Knowledge Bases for Amazon Bedrock is a fully managed capability that helps you implement the entire RAG workflow from ingestion to retrieval and prompt augmentation without having to build custom integrations to data sources and manage data flows.

Today, we are announcing the availability of MongoDB Atlas as a vector store in Knowledge Bases for Amazon Bedrock. With MongoDB Atlas vector store integration, you can build RAG solutions to securely connect your organization’s private data sources to FMs in Amazon Bedrock. This integration adds to the list of vector stores supported by Knowledge Bases for Amazon Bedrock, including Amazon Aurora PostgreSQL-Compatible Edition, vector engine for Amazon OpenSearch Serverless, Pinecone, and Redis Enterprise Cloud.

Build RAG applications with MongoDB Atlas and Knowledge Bases for Amazon Bedrock
Vector Search in MongoDB Atlas is powered by the vectorSearch index type. In the index definition, you must specify the field that contains the vector data as the vector type. Before using MongoDB Atlas vector search in your application, you will need to create an index, ingest source data, create vector embeddings and store them in a MongoDB Atlas collection. To perform queries, you will need to convert the input text into a vector embedding, and then use an aggregation pipeline stage to perform vector search queries against fields indexed as the vector type in a vectorSearch type index.

Thanks to the MongoDB Atlas integration with Knowledge Bases for Amazon Bedrock, most of the heavy lifting is taken care of. Once the vector search index and knowledge base are configured, you can incorporate RAG into your applications. Behind the scenes, Amazon Bedrock will convert your input (prompt) into embeddings, query the knowledge base, augment the FM prompt with the search results as contextual information and return the generated response.

Let me walk you through the process of setting up MongoDB Atlas as a vector store in Knowledge Bases for Amazon Bedrock.

Configure MongoDB Atlas
Start by creating a MongoDB Atlas cluster on AWS. Choose an M10 dedicated cluster tier. Once the cluster is provisioned, create a database and collection. Next, create a database user and grant it the Read and write to any database role. Select Password as the Authentication Method. Finally, configure network access to modify the IP Access List – add IP address 0.0.0.0/0 to allow access from anywhere.

Use the following index definition to create the Vector Search index:

{
  "fields": [
    {
      "numDimensions": 1536,
      "path": "AMAZON_BEDROCK_CHUNK_VECTOR",
      "similarity": "cosine",
      "type": "vector"
    },
    {
      "path": "AMAZON_BEDROCK_METADATA",
      "type": "filter"
    },
    {
      "path": "AMAZON_BEDROCK_TEXT_CHUNK",
      "type": "filter"
    }
  ]
}

Configure the knowledge base
Create an AWS Secrets Manager secret to securely store the MongoDB Atlas database user credentials. Choose Other as the Secret type. Create an Amazon Simple Storage Service (Amazon S3) storage bucket and upload the Amazon Bedrock documentation user guide PDF. Later, you will use the knowledge base to ask questions about Amazon Bedrock.

You can also use another document of your choice because Knowledge Base supports multiple file formats (including text, HTML, and CSV).

Navigate to the Amazon Bedrock console and refer to the Amzaon Bedrock User Guide to configure the knowledge base. In the Select embeddings model and configure vector store, choose Titan Embeddings G1 – Text as the embedding model. From the list of databases, choose MongoDB Atlas.

Enter the basic information for the MongoDB Atlas cluster (Hostname, Database name, etc.) as well as the ARN of the AWS Secrets Manager secret you had created earlier. In the Metadata field mapping attributes, enter the vector store specific details. They should match the vector search index definition you used earlier.

Initiate the knowledge base creation. Once complete, synchronise the data source (S3 bucket data) with the MongoDB Atlas vector search index.

Once the synchronization is complete, navigate to MongoDB Atlas to confirm that the data has been ingested into the collection you created.

Notice the following attributes in each of the MongoDB Atlas documents:

  • AMAZON_BEDROCK_TEXT_CHUNK – Contains the raw text for each data chunk.
  • AMAZON_BEDROCK_CHUNK_VECTOR – Contains the vector embedding for the data chunk.
  • AMAZON_BEDROCK_METADATA – Contains additional data for source attribution and rich query capabilities.

Test the knowledge base
It’s time to ask questions about Amazon Bedrock by querying the knowledge base. You will need to choose a foundation model. I picked Claude v2 in this case and used “What is Amazon Bedrock” as my input (query).

If you are using a different source document, adjust the questions accordingly.

You can also change the foundation model. For example, I switched to Claude 3 Sonnet. Notice the difference in the output and select Show source details to see the chunks cited for each footnote.

Integrate knowledge base with applications
To build RAG applications on top of Knowledge Bases for Amazon Bedrock, you can use the RetrieveAndGenerate API which allows you to query the knowledge base and get a response.

Here is an example using the AWS SDK for Python (Boto3):

import boto3

bedrock_agent_runtime = boto3.client(
    service_name = "bedrock-agent-runtime"
)

def retrieveAndGenerate(input, kbId):
    return bedrock_agent_runtime.retrieve_and_generate(
        input={
            'text': input
        },
        retrieveAndGenerateConfiguration={
            'type': 'KNOWLEDGE_BASE',
            'knowledgeBaseConfiguration': {
                'knowledgeBaseId': kbId,
                'modelArn': 'arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-3-sonnet-20240229-v1:0'
                }
            }
        )

response = retrieveAndGenerate("What is Amazon Bedrock?", "BFT0P4NR1U")["output"]["text"]

If you want to further customize your RAG solutions, consider using the Retrieve API, which returns the semantic search responses that you can use for the remaining part of the RAG workflow.

import boto3

bedrock_agent_runtime = boto3.client(
    service_name = "bedrock-agent-runtime"
)

def retrieve(query, kbId, numberOfResults=5):
    return bedrock_agent_runtime.retrieve(
        retrievalQuery= {
            'text': query
        },
        knowledgeBaseId=kbId,
        retrievalConfiguration= {
            'vectorSearchConfiguration': {
                'numberOfResults': numberOfResults
            }
        }
    )

response = retrieve("What is Amazon Bedrock?", "BGU0Q4NU0U")["retrievalResults"]

Things to know

  • MongoDB Atlas cluster tier – This integration requires requires an Atlas cluster tier of at least M10.
  • AWS PrivateLink – For the purposes of this demo, MongoDB Atlas database IP Access List was configured to allow access from anywhere. For production deployments, AWS PrivateLink is the recommended way to have Amazon Bedrock establish a secure connection to your MongoDB Atlas cluster. Refer to the Amazon Bedrock User guide (under MongoDB Atlas) for details.
  • Vector embedding size – The dimension size of the vector index and the embedding model should be the same. For example, if you plan to use Cohere Embed (which has a dimension size of 1024) as the embedding model for the knowledge base, make sure to configure the vector search index accordingly.
  • Metadata filters – You can add metadata for your source files to retrieve a well-defined subset of the semantically relevant chunks based on applied metadata filters. Refer to the documentation to learn more about how to use metadata filters.

Now available
MongoDB Atlas vector store in Knowledge Bases for Amazon Bedrock is available in the US East (N. Virginia) and US West (Oregon) Regions. Be sure to check the full Region list for future updates.

Amazon Titan Text V2 now available in Amazon Bedrock, optimized for improving RAG

Post Syndicated from Sébastien Stormacq original https://aws.amazon.com/blogs/aws/amazon-titan-text-v2-now-available-in-amazon-bedrock-optimized-for-improving-rag/

The Amazon Titan family of models, available exclusively in Amazon Bedrock, is built on top of 25 years of Amazon expertise in artificial intelligence (AI) and machine learning (ML) advancements. Amazon Titan foundation models (FMs) offer a comprehensive suite of pre-trained image, multimodal, and text models accessible through a fully managed API. Trained on extensive datasets, Amazon Titan models are powerful and versatile, designed for a range of applications while adhering to responsible AI practices.

The latest addition to the Amazon Titan family is Amazon Titan Text Embeddings V2, the second-generation text embeddings model from Amazon now available within Amazon Bedrock. This new text embeddings model is optimized for Retrieval-Augmented Generation (RAG). It is pre-trained on 100+ languages and on code.

Amazon Titan Text Embeddings V2 now lets you choose the size of of the output vector (either 256, 512, or 1024). Larger vector sizes create more detailed responses, but will also increase the computational time. Shorter vector lengths are less detailed but will improve the response time. Using smaller vectors helps to reduce your storage costs and the latency to search and retrieve document extracts from a vector database. We measured the accuracy of the vectors generated by Amazon Titan Text Embeddings V2 and we observed that vectors with 512 dimensions keep approximately 99 percent of the accuracy provided by vectors with 1024 dimensions. Vectors with 256 dimensions keep 97 percent of the accuracy. This means that you can save 75 percent in vector storage (from 1024 down to 256 dimensions) and keep approximately 97 percent of the accuracy provided by larger vectors.

Amazon Titan Text Embeddings V2 also proposes an improved unit vector normalization that helps improve the accuracy when measuring vector similarity. You can choose between normalized or unnormalized versions of the embeddings based on your use case (normalized is more accurate for RAG use cases). Normalization of a vector is the process of scaling it to have a unit length or magnitude of 1. It is useful to ensure that all vectors have the same scale and contribute equally during vector operations, preventing some vectors from dominating others due to their larger magnitudes.

This new text embeddings model is well-suited for a variety of use cases. It can help you perform semantic searches on documents, for example, to detect plagiarism. It can classify labels into data-based learned representations, for example, to categorize movies into genres. It can also improve the quality and relevance of retrieved or generated search results, for example, recommending content based on interest using RAG.

How embeddings help to improve accuracy of RAG
Imagine you’re a superpowered research assistant for a large language model (LLM). LLMs are like those brainiacs who can write different creative text formats, but their knowledge comes from the massive datasets they were trained on. This training data might be a bit outdated or lack specific details for your needs.

This is where RAG comes in. RAG acts like your assistant, fetching relevant information from a custom source, like a company knowledge base. When the LLM needs to answer a question, RAG provides the most up-to-date information to help it generate the best possible response.

To find the most up-to-date information, RAG uses embeddings. Imagine these embeddings (or vectors) as super-condensed summaries that capture the key idea of a piece of text. A high-quality embeddings model, such as Amazon Titan Text Embeddings V2, can create these summaries accurately, like a great assistant who can quickly grasp the important points of each document. This ensures RAG retrieves the most relevant information for the LLM, leading to more accurate and on-point answers.

Think of it like searching a library. Each page of the book is indexed and represented by a vector. With a bad search system, you might end up with a pile of books that aren’t quite what you need. But with a great search system that understands the content (like a high-quality embeddings model), you’ll get exactly what you’re looking for, making the LLM’s job of generating the answer much easier.

Amazon Titan Text Embeddings V2 overview
Amazon Titan Text Embeddings V2 is optimized for high accuracy and retrieval performance at smaller dimensions for reduced storage and latency. We measured that vectors with 512 dimensions maintain approximately 99 percent of the accuracy provided by vectors with 1024 dimensions. Those with 256 dimensions offer 97 percent of the accuracy.

Max tokens 8,192
Languages 100+ in pre-training
Fine-tuning supported No
Normalization supported Yes
Vector size 256, 512, 1,024 (default)

How to use Amazon Titan Text Embeddings V2
It’s very likely you will interact with Amazon Titan Text Embeddings V2 indirectly through Knowledge Bases for Amazon Bedrock. Knowledge Bases takes care of the heavy lifting to create a RAG-based application. However, you can also use the Amazon Bedrock Runtime API to directly invoke the model from your code. Here is a simple example in the Swift programming language (just to show you you can use any programming language, not just Python):

import Foundation
import AWSBedrockRuntime 

let text = "This is the text to transform in a vector"

// create an API client
let client = try BedrockRuntimeClient(region: "us-east-1")

// create the request 
let request = InvokeModelInput(
   accept: "application/json",
   body: """
   {
      "inputText": "\(text)",
      "dimensions": 256,
      "normalize": true
   }
   """.data(using: .utf8), 
   contentType: "application/json",
   modelId: "amazon.titan-embed-text-v2:0")

// send the request 
let response = try await client.invokeModel(input: request)

// decode the response
let response = String(data: (response.body!), encoding: .utf8)

print(response ?? "")

The model takes three parameters in its payload:

  • inputText – The text to convert to embeddings.
  • normalize – A flag indicating whether or not to normalize the output embeddings. It defaults to true, which is optimal for RAG use cases.
  • dimensions – The number of dimensions the output embeddings should have. Three values are accepted: 256, 512, and 1024 (the default value).

I added the dependency on the AWS SDK for Swift in my Package.swift. I type swift run to build and run this code. It prints the following output (truncated to keep it brief):

{"embedding":[-0.26757812,0.15332031,-0.015991211...-0.8203125,0.94921875],
"inputTextTokenCount":9}

As usual, do not forget to enable access to the new model in the Amazon Bedrock console before using the API.

Amazon Titan Text Embeddings V2 will soon be the default LLM proposed by Knowledge Bases for Amazon Bedrock. Your existing knowledge bases created with the original Amazon Titan Text Embeddings model will continue to work without changes.

To learn more about the Amazon Titan family of models, view the following video:

The new Amazon Titan Text Embeddings V2 model is available today in Amazon Bedrock in the US East (N. Virginia) and US West (Oregon) AWS Regions. Check the full Region list for future updates.

Run scalable, enterprise-grade generative AI workloads with Cohere Command R & R+, now available in Amazon Bedrock

Post Syndicated from Veliswa Boya original https://aws.amazon.com/blogs/aws/run-scalable-enterprise-grade-generative-ai-workloads-with-cohere-r-r-now-available-in-amazon-bedrock/

In November 2023, we made two new Cohere models available in Amazon Bedrock (Cohere Command Light and Cohere Embed English). Today, we’re announcing the addition of two more Cohere models in Amazon Bedrock; Cohere Command R and Command R+.

Organizations need generative artificial intelligence (generative AI) models to securely interact with information stored in their enterprise data sources. Both Command R and Command R+ are powerful, scalable large language models (LLMs), purpose-built for real-world, enterprise-grade workloads. These models are multilingual and are focused on balancing high efficiency with strong accuracy to excel at capabilities such as Retrieval-Augmented Generation (RAG), and tool use to enable enterprises to move beyond proof-of-concept (POC), and into production using artificial intelligence (AI).

Command R is a scalable multilingual generative model targeting RAG and tool use to enable production-scale AI for enterprises. Command R+ is a state-of-the-art RAG-optimized model designed to tackle enterprise-grade workloads and optimize business AI applications. Command R+ is optimized for advanced RAG to provide enterprise-ready, highly reliable, and verifiable responses due to in-line citations which come standard with this model. With these new Cohere models in Bedrock, you can scale with AI to quickly find the most relevant information to support tasks across business functions like finance, human resources (HR), sales, marketing, and customer support, among others, in a range of business sectors. Tool use is also available in Command R+. Command R+ is a strong multilingual model, and similarly to Command R, features a tokenizer that compresses non-English text much better than the tokenizer used for other models in the market.

Getting started with Command R and Command R+
To get started with both models in Amazon Bedrock, you first need to get access to the models. In the Amazon Bedrock console, choose Model access, and then choose Manage model access. Next, choose your preferred model(s), and then choose Save changes. As you can see, you now have six Cohere models to choose from in Amazon Bedrock – including Command R and Command R+ – giving you greater choice and flexibility to use the optimal models for your specific business needs.

Once you have access to your preferred model, you can use the model in Amazon Bedrock. Refresh the base models table to view the updated status.

The models have been trained to respond in the language of the user such as English, French, Spanish, Italian, German, Brazilian Portuguese, Japanese, Korean, Simplified Chinese, and Arabic. Here’s an example:

Prompt

<s>"Écris une description de produit pour une voiture électrique en 50 à 75 mots"

Output

Découvrez la voiture électrique qui va révolutionner votre façon de conduire.
Avec son design élégant, cette voiture offre une expérience de conduite unique
avec une accélération puissante et une autonomie impressionnante. Sa
technologie avancée vous garantit une charge rapide et une fiabilité inégalée.
Avec sa conception innovante et durable, cette voiture est parfaite pour les 
trajets urbains et les longues distances. Profitez d'une conduite silencieuse
et vivez l'expérience de la voiture électrique!

Programmatically interact with Command R and Command R+
You can also use AWS Command Line Interface (CLI) and AWS Software Development Kit (SDK) to make various calls using Amazon Bedrock APIs. Following, is a sample code in Python that interacts with Amazon Bedrock Runtime APIs with AWS SDK. Taking the same text generation prompt I used earlier, here is how it looks when used programmatically. In this example I’m interacting with the Command R model. Back to Python, I first run the ListFoundationModels API call to discover the modelId for Command R.

import boto3
import json
import numpy

bedrock = boto3.client(service_name='bedrock', region_name='us-east-1')

listModels = bedrock.list_foundation_models(byProvider='cohere')
print("\n".join(list(map(lambda x: f"{x['modelName']} : { x['modelId'] }", listModels['modelSummaries']))))

Running this code gives the list:

Command : cohere.command-text-v14
Command Light : cohere.command-light-text-v14
Embed English : cohere.embed-english-v3
Embed Multilingual : cohere.embed-multilingual-v3
Command R: cohere.command-r-v1:0
Command R+: cohere.command-r-plus-v1:0

From this list, I select cohere.command-r-v1:0 model ID and write the code to generate the text as shown earlier in this post.

import boto3
import json

bedrock = boto3.client(service_name="bedrock-runtime", region_name='us-east-1')

prompt = """
<s>Écris une description de produit pour une voiture électrique en 50 à 75 mots

body = json.dumps({
    "prompt": prompt,
    "max_tokens": 512,
    "top_p": 0.8,
    "temperature": 0.5,
})

modelId = "cohere.command-r-v1:0"

accept = "application/json"
contentType = "application/json"

response = bedrock.invoke_model(
    body=body,
    modelId=modelId,
    accept=accept,
    contentType=contentType
)

print(json.loads(response.get('body').read()))

You can get JSON formatted output as like:

Découvrez la voiture électrique qui va révolutionner votre façon de conduire.
Avec son design élégant, cette voiture offre une expérience de conduite unique
avec une accélération puissante et une autonomie impressionnante. Sa
technologie avancée vous garantit une charge rapide et une fiabilité inégalée.
Avec sa conception innovante et durable, cette voiture est parfaite pour les 
trajets urbains et les longues distances. Profitez d'une conduite silencieuse
et vivez l'expérience de la voiture électrique!

AWS Weekly Roundup: Amazon Bedrock, AWS CodeBuild, Amazon CodeCatalyst, and more (April 29, 2024)

Post Syndicated from Danilo Poccia original https://aws.amazon.com/blogs/aws/aws-weekly-roundup-amazon-bedrock-aws-codebuild-amazon-codecatalyst-and-more-april-29-2024/

This was a busy week for Amazon Bedrock with many new features! Using GitHub Actions with AWS CodeBuild is much easier. Also, Amazon Q in Amazon CodeCatalyst can now manage more complex issues.

I was amazed to meet so many new and old friends at the AWS Summit London. To give you a quick glimpse, here’s AWS Hero Yan Cui starting his presentation at the AWS Community stage.

AWS Community at the AWS Summit London 2024

Last week’s launches
With so many interesting new features, I start with generative artificial intelligence (generative AI) and then move to the other topics. Here’s what got my attention:

Amazon Bedrock – For supported architectures such as Llama, Mistral, or Flan T5, you can now import custom models and access them on demand. Model evaluation is now generally available to help you evaluate, compare, and select the best foundation models (FMs) for your specific use case. You can now access Meta’s Llama 3 models.

Agents for Amazon Bedrock – A simplified agent creation and return of control, so that you can define an action schema and get the control back to perform those action without needing to create a specific AWS Lambda function. Agents also added support for Anthropic Claude 3 Haiku and Sonnet to help build faster and more intelligent agents.

Knowledge Bases for Amazon Bedrock – You can now ingest data from up to five data sources and provide more complete answers. In the console, you can now chat with one of your documents without needing to set up a vector database (read more in this Machine Learning blog post).

Guardrails for Amazon Bedrock – The capability to implement safeguards based on your use cases and responsible AI policies is now available with new safety filters and privacy controls.

Amazon Titan – The new watermark detection feature is now generally available in Amazon Bedrock. In this way, you can identify images generated by Amazon Titan Image Generator using an invisible watermark present in all images generated by Amazon Titan.

Amazon CodeCatalyst – Amazon Q can now split complex issues into separate, simpler tasks that can then be assigned to a user or back to Amazon Q. CodeCatalyst now also supports approval gates within a workflow. Approval gates pause a workflow that is building, testing, and deploying code so that a user can validate whether it should be allowed to proceed.

Amazon EC2 – You can now remove an automatically assigned public IPv4 address from an EC2 instance. If you no longer need the automatically assigned public IPv4 (for example, because you are migrating to using a private IPv4 address for SSH with EC2 instance connect), you can use this option to quickly remove the automatically assigned public IPv4 address and reduce your public IPv4 costs.

Network Load Balancer – Now supports Resource Map in AWS Management Console, a tool that displays all your NLB resources and their relationships in a visual format on a single page. Note that Application Load Balancer already supports Resource Map in the console.

AWS CodeBuild – Now supports managed GitHub Action self-hosted runners. You can configure CodeBuild projects to receive GitHub Actions workflow job events and run them on CodeBuild ephemeral hosts.

Amazon Route 53 – You can now define a standard DNS configuration in the form of a Profile, apply this configuration to multiple VPCs, and share it across AWS accounts.

AWS Direct Connect – Hosted connections now support capacities up to 25 Gbps. Before, the maximum was 10 Gbps. Higher bandwidths simplify deployments of applications such as advanced driver assistance systems (ADAS), media and entertainment (M&E), artificial intelligence (AI), and machine learning (ML).

NoSQL Workbench for Amazon DynamoDB – A revamped operation builder user interface to help you better navigate, run operations, and browse your DynamoDB tables.

Amazon GameLift – Now supports in preview end-to-end development of containerized workloads, including deployment and scaling on premises, in the cloud, or for hybrid configurations. You can use containers for building, deploying, and running game server packages.

Let’s Architect! Discovering Generative AI on AWS

Post Syndicated from Luca Mezzalira original https://aws.amazon.com/blogs/architecture/lets-architect-generative-ai/

Generative artificial intelligence (generative AI) is a type of AI used to generate content, including conversations, images, videos, and music. Generative AI can be used directly to build customer-facing features (a chatbot or an image generator), or it can serve as an underlying component in a more complex system. For example, it can generate embeddings (or compressed representations) or any other artifact necessary to improve downstream machine learning (ML) models or back-end services.

With the advent of generative AI, it’s fundamental to understand what it is, how it works under the hood, and which options are available for putting it into production. In some cases, it can also be helpful to move closer to the underlying model in order to fine tune or drive domain-specific improvements. With this edition of Let’s Architect!, we’ll cover these topics and share an initial set of methodologies to put generative AI into production. We’ll start with a broad introduction to the domain and then share a mix of videos, blogs, and hands-on workshops.

Navigating the future of AI 

Many teams are turning to open source tools running on Kubernetes to help accelerate their ML and generative AI journeys. In this video session, experts discuss why Kubernetes is ideal for ML, then tackle challenges like dependency management and security. You will learn how tools like Ray, JupyterHub, Argo Workflows, and Karpenter can accelerate your path to building and deploying generative AI applications on Amazon Elastic Kubernetes Service (Amazon EKS). A real-world example showcases how Adobe leveraged Amazon EKS to achieve faster time-to-market and reduced costs. You will be also introduced to Data on EKS, a new AWS project offering best practices for deploying various data workloads on Amazon EKS.

Take me to this video!

Containers are a powerful tool for creating reproducible research and production environments for ML.

SaaS meets AI/ML & generative AI: Multi-tenant patterns & strategies

Working with AI/ML workloads and generative AI in a production environment requires appropriate system design and careful considerations for tenant separation in the context of SaaS. You’ll need to think about how the different tenants are mapped to models, how inferencing is scaled, how solutions are integrated with other upstream/downstream services, and how large language models (LLMs) can be fine-tuned to meet tenant-specific needs.

This video drills down into the concept of multi-tenancy for AI/ML workloads, including the common design, performance, isolation, and experience challenges that you can find during your journey. You will also become familiar with concepts like RAG (used to enrich the LLMs with contextual information) and fine tuning through practical examples.

Take me to this video!

Supporting different tenants might need fetching different context information with RAGs or offering different options for fine-tuning.

Achieve DevOps maturity with BMC AMI zAdviser Enterprise and Amazon Bedrock

DevOps Research and Assessment (DORA) metrics, which measure critical DevOps performance indicators like lead time, are essential to engineering practices, as shown in the Accelerate book‘s research. By leveraging generative AI technology, the zAdviser Enterprise platform can now offer in-depth insights and actionable recommendations to help organizations optimize their DevOps practices and drive continuous improvement. This blog demonstrates how generative AI can go beyond language or image generation, applying to a wide spectrum of domains.

Take me to this blog post!

Generative AI is used to provide summarization, analysis, and recommendations for improvement based on the DORA metrics.

Hands-on Generative AI: AWS workshops

Getting hands on is often the best way to understand how everything works in practice and create the mental model to connect theoretical foundations with some real-world applications.

Generative AI on Amazon SageMaker shows how you can build, train, and deploy generative AI models. You can learn about options to fine-tune, use out-of-the-box existing models, or even customize the existing open source models based on your needs.

Building with Amazon Bedrock and LangChain demonstrates how an existing fully-managed service provided by AWS can be used when you work with foundational models, covering a wide variety of use cases. Also, if you want a quick guide for prompt engineering, you can check out the PartyRock lab in the workshop.

Meta’s Llama 3 models are now available in Amazon Bedrock

Post Syndicated from Channy Yun original https://aws.amazon.com/blogs/aws/metas-llama-3-models-are-now-available-in-amazon-bedrock/

Today, we are announcing the general availability of Meta’s Llama 3 models in Amazon Bedrock. Meta Llama 3 is designed for you to build, experiment, and responsibly scale your generative artificial intelligence (AI) applications. New Llama 3 models are the most capable to support a broad range of use cases with improvements in reasoning, code generation, and instruction.

According to Meta’s Llama 3 announcement, the Llama 3 model family is a collection of pre-trained and instruction-tuned large language models (LLMs) in 8B and 70B parameter sizes. These models have been trained on over 15 trillion tokens of data—a training dataset seven times larger than that used for Llama 2 models, including four times more code, which supports an 8K context length that doubles the capacity of Llama 2.

You can now use two new Llama 3 models in Amazon Bedrock, further increasing model choice within Amazon Bedrock. These models provide the ability for you to easily experiment with and evaluate even more top foundation models (FMs) for your use case:

  • Llama 3 8B is ideal for limited computational power and resources, and edge devices. The model excels at text summarization, text classification, sentiment analysis, and language translation.
  • Llama 3 70B is ideal for content creation, conversational AI, language understanding, research development, and enterprise applications. The model excels at text summarization and accuracy, text classification and nuance, sentiment analysis and nuance reasoning, language modeling, dialogue systems, code generation, and following instructions.

Meta is also currently training additional Llama 3 models over 400B parameters in size. These 400B models will have new capabilities, including multimodality, multiple languages support, and a much longer context window. When released, these models will be ideal for content creation, conversational AI, language understanding, research and development (R&D), and enterprise applications.

Llama 3 models in action
If you are new to using Meta models, go to the Amazon Bedrock console and choose Model access on the bottom left pane. To access the latest Llama 3 models from Meta, request access separately for Llama 3 8B Instruct or Llama 3 70B Instruct.

To test the Meta Llama 3 models in the Amazon Bedrock console, choose Text or Chat under Playgrounds in the left menu pane. Then choose Select model and select Meta as the category and Llama 8B Instruct or Llama 3 70B Instruct as the model.

By choosing View API request, you can also access the model using code examples in the AWS Command Line Interface (AWS CLI) and AWS SDKs. You can use model IDs such as meta.llama3-8b-instruct-v1 or meta.llama3-70b-instruct-v1.

Here is a sample of the AWS CLI command:

$ aws bedrock-runtime invoke-model \
  --model-id meta.llama3-8b-instruct-v1:0 \
  --body "{\"prompt\":\"Simply put, the theory of relativity states that\\n the laws of physics are the same everywhere in the universe, and that the passage of time and the length of objects can vary depending on their speed and position in a gravitational field \",\"max_gen_len\":512,\"temperature\":0.5,\"top_p\":0.9}" \
  --cli-binary-format raw-in-base64-out \
  --region us-east-1 \
  invoke-model-output.txt

You can use code examples for Amazon Bedrock using AWS SDKs to build your applications with various programming languages. The following Python code examples show how to invoke the Llama 3 Chat model in Amazon Bedrock for text generation.

def invoke_llama3(self, prompt):
        try:
            body = {
                "prompt": prompt,
                "temperature": 0.5,
                "top_p": 0.9,
                "max_gen_len": 512,
            }

            response = self.bedrock_runtime_client.invoke_model(
                modelId="meta.llama3-8b-instruct-v1:0", body=json.dumps(body)
            )

            response_body = json.loads(response["body"].read())
            completion = response_body["generation"]

            return completion

        except ClientError:
            logger.error("Couldn't invoke Llama 3")
            raise

You can use these Llama 3 models for a variety of tasks, such as question answering, language translation, sentiment analysis, and more. Here is an example of Llama 3 models with few-shot in-context learning where we provide training samples available to the model.

Input: Translate English to French:
sea otter => loutre de mer
peppermint => menthe poivrée
plush girafe => girafe peluche
cheese =>
Output:  fromage
panda => panda
penguin => pingouin
polar bear => ours polaire
puffin => macareux
sloth => paresseux
walrus => morse
whale => baleine
zebra => z\u00e8bre

Translate English to German:
sea otter => Seeotter

You can also use Llama 3 instruct models optimized for dialogue use cases. The input to the instruct model endpoints is the previous history between the chat assistant and the user. So, you can ask questions contextual to the conversation that has happened so far and provide the system configuration, such as personas, which define the chat assistant’s behavior in the following format:

<|begin_of_text|><|start_header_id|>system<|end_header_id|>
[SYSTEM_TEXT]<|eot_id|><|start_header_id|>user<|end_header_id|>
[USER_TEXT]<|eot_id|><|start_header_id|>assistant<|end_header_id|>

In the following example, the user has a conversation with the assistant about tourist sites in Paris. Then, the user inquires about the first option recommended by the chat assistant.

Input: <|begin_of_text|><|start_header_id|>user<|end_header_id|>\n\n
I am going to Paris, what should I see?<|eot_id|><|start_header_id|>assistant<|end_header_id|>\n\n
Paris, the capital of France, is known for its stunning architecture, art museums, historical landmarks, and romantic atmosphere. Here are some of the top attractions to see in Paris:\n\n
1. The Eiffel Tower: The iconic Eiffel Tower is one of the most recognizable landmarks in the world and offers breathtaking views of the city.\n
2. The Louvre Museum: The Louvre is one of the world's largest and most famous museums, housing an impressive collection of art and artifacts, including the Mona Lisa.\n
3. Notre-Dame Cathedral: This beautiful cathedral is one of the most famous landmarks in Paris and is known for its Gothic architecture and stunning stained glass windows.\n\n
These are just a few of the many attractions that Paris has to offer. With so much to see and do, it's no wonder that Paris is one of the most popular tourist destinations in the world.<|eot_id|><|start_header_id|>user<|end_header_id|>\n\n
What is so great about #1?<|eot_id|><|start_header_id|>assistant<|end_header_id|>\n\n
Output: The Eiffel Tower! It's an iconic symbol of Paris and one of the most recognizable landmarks in the world. Here are some reasons why it's so great:\n\n
1. **Engineering marvel**: When it was built for the 1889 World's Fair, the Eiffel Tower was a groundbreaking feat of engineering. It was the tallest structure in the world at the time, standing at 324 meters (1,063 feet).\n
2. **Panoramic views**: The Eiffel Tower offers breathtaking 360-degree views of the city from its observation decks. You can see many of Paris' famous landmarks, such as the Seine River, the Louvre, and Montmartre.\n
3. **Romantic atmosphere**: The Eiffel Tower is often associated with romance and is a popular spot for proposals, weddings, and romantic dinners. The tower's iron latticework and twinkling lights at night add to its romantic ambiance.\n
4. **Historical significance**: The Eiffel Tower has played a significant role in French history, serving as a communication tower during World War I and a symbol of French culture and engineering.\n
5. **Accessibility**: The Eiffel Tower is easily accessible by public transportation or on foot, and there are various ways to experience it, including taking the stairs, elevator, or a guided tour.\n
6. **Nighttime spectacle**: The Eiffel Tower is even more magical at night, when it's illuminated with thousands of twinkling lights. The light show, known as the \"Eiffel Tower Sparkle,\" takes place every hour on the hour from dusk to midnight.\n
7. **Iconic status**: The Eiffel Tower has been featured in countless films, literature, and art, making it an instantly recognizable symbol of Paris and France.\n\n
Overall, the Eiffel Tower is a must-visit attraction in Paris, offering a unique combination of history, engineering, romance, and stunning views.

Guardrails for Amazon Bedrock now available with new safety filters and privacy controls

Post Syndicated from Esra Kayabali original https://aws.amazon.com/blogs/aws/guardrails-for-amazon-bedrock-now-available-with-new-safety-filters-and-privacy-controls/

Today, I am happy to announce the general availability of Guardrails for Amazon Bedrock, first released in preview at re:Invent 2023. With Guardrails for Amazon Bedrock, you can implement safeguards in your generative artificial intelligence (generative AI) applications that are customized to your use cases and responsible AI policies. You can create multiple guardrails tailored to different use cases and apply them across multiple foundation models (FMs), improving end-user experiences and standardizing safety controls across generative AI applications. You can use Guardrails for Amazon Bedrock with all large language models (LLMs) in Amazon Bedrock, including fine-tuned models.

Guardrails for Bedrock offers industry-leading safety protection on top of the native capabilities of FMs, helping customers block as much as 85% more harmful content than protection natively provided by some foundation models on Amazon Bedrock today. Guardrails for Amazon Bedrock is the only responsible AI capability offered by top cloud providers that enables customers to build and customize safety and privacy protections for their generative AI applications in a single solution, and it works with all large language models (LLMs) in Amazon Bedrock, as well as fine-tuned models.

Aha! is a software company that helps more than 1 million people bring their product strategy to life. “Our customers depend on us every day to set goals, collect customer feedback, and create visual roadmaps,” said Dr. Chris Waters, co-founder and Chief Technology Officer at Aha!. “That is why we use Amazon Bedrock to power many of our generative AI capabilities. Amazon Bedrock provides responsible AI features, which enable us to have full control over our information through its data protection and privacy policies, and block harmful content through Guardrails for Bedrock. We just built on it to help product managers discover insights by analyzing feedback submitted by their customers. This is just the beginning. We will continue to build on advanced AWS technology to help product development teams everywhere prioritize what to build next with confidence.”

In the preview post, Antje showed you how to use guardrails to configure thresholds to filter content across harmful categories and define a set of topics that need to be avoided in the context of your application. The Content filters feature now has two additional safety categories: Misconduct for detecting criminal activities and Prompt Attack for detecting prompt injection and jailbreak attempts. We also added important new features, including sensitive information filters to detect and redact personally identifiable information (PII) and word filters to block inputs containing profane and custom words (for example, harmful words, competitor names, and products).

Guardrails for Amazon Bedrock sits in between the application and the model. Guardrails automatically evaluates everything going into the model from the application and coming out of the model to the application to detect and help prevent content that falls into restricted categories.

You can recap the steps in the preview release blog to learn how to configure Denied topics and Content filters. Let me show you how the new features work.

New features
To start using Guardrails for Amazon Bedrock, I go to the AWS Management Console for Amazon Bedrock, where I can create guardrails and configure the new capabilities. In the navigation pane in the Amazon Bedrock console, I choose Guardrails, and then I choose Create guardrail.

I enter the guardrail Name and Description. I choose Next to move to the Add sensitive information filters step.

I use Sensitive information filters to detect sensitive and private information in user inputs and FM outputs. Based on the use cases, I can select a set of entities to be either blocked in inputs (for example, a FAQ-based chatbot that doesn’t require user-specific information) or redacted in outputs (for example, conversation summarization based on chat transcripts). The sensitive information filter supports a set of predefined PII types. I can also define custom regex-based entities specific to my use case and needs.

I add two PII types (Name, Email) from the list and add a regular expression pattern using Booking ID as Name and [0-9a-fA-F]{8} as the Regex pattern.

I choose Next and enter custom messages that will be displayed if my guardrail blocks the input or the model response in the Define blocked messaging step. I review the configuration at the last step and choose Create guardrail.

I navigate to the Guardrails Overview page and choose the Anthropic Claude Instant 1.2 model using the Test section. I enter the following call center transcript in the Prompt field and choose Run.

Please summarize the below call center transcript. Put the name, email and the booking ID to the top:
Agent: Welcome to ABC company. How can I help you today?
Customer: I want to cancel my hotel booking.
Agent: Sure, I can help you with the cancellation. Can you please provide your booking ID?
Customer: Yes, my booking ID is 550e8408.
Agent: Thank you. Can I have your name and email for confirmation?
Customer: My name is Jane Doe and my email is [email protected]
Agent: Thank you for confirming. I will go ahead and cancel your reservation.

Guardrail action shows there are three instances where the guardrails came in to effect. I use View trace to check the details. I notice that the guardrail detected the Name, Email and Booking ID and masked them in the final response.

I use Word filters to block inputs containing profane and custom words (for example, competitor names or offensive words). I check the Filter profanity box. The profanity list of words is based on the global definition of profanity. Additionally, I can specify up to 10,000 phrases (with a maximum of three words per phrase) to be blocked by the guardrail. A blocked message will show if my input or model response contain these words or phrases.

Now, I choose Custom words and phrases under Word filters and choose Edit. I use Add words and phrases manually to add a custom word CompetitorY. Alternatively, I can use Upload from a local file or Upload from S3 object if I need to upload a list of phrases. I choose Save and exit to return to my guardrail page.

I enter a prompt containing information about a fictional company and its competitor and add the question What are the extra features offered by CompetitorY?. I choose Run.

I use View trace to check the details. I notice that the guardrail intervened according to the policies I configured.

Now available
Guardrails for Amazon Bedrock is now available in US East (N. Virginia) and US West (Oregon) Regions.

For pricing information, visit the Amazon Bedrock pricing page.

Agents for Amazon Bedrock: Introducing a simplified creation and configuration experience

Post Syndicated from Danilo Poccia original https://aws.amazon.com/blogs/aws/agents-for-amazon-bedrock-introducing-a-simplified-creation-and-configuration-experience/

With Agents for Amazon Bedrock, applications can use generative artificial intelligence (generative AI) to run tasks across multiple systems and data sources. Starting today, these new capabilities streamline the creation and management of agents:

Quick agent creation – You can now quickly create an agent and optionally add instructions and action groups later, providing flexibility and agility for your development process.

Agent builder – All agent configurations can be operated in the new agent builder section of the console.

Simplified configuration – Action groups can use a simplified schema that just lists functions and parameters without having to provide an API schema.

Return of control –You can skip using an AWS Lambda function and return control to the application invoking the agent. In this way, the application can directly integrate with systems outside AWS or call internal endpoints hosted in any Amazon Virtual Private Cloud (Amazon VPC) without the need to integrate the required networking and security configurations with a Lambda function.

Infrastructure as code – You can use AWS CloudFormation to deploy and manage agents with the new simplified configuration, ensuring consistency and reproducibility across environments for your generative AI applications.

Let’s see how these enhancements work in practice.

Creating an agent using the new simplified console
To test the new experience, I want to build an agent that can help me reply to an email containing customer feedback. I can use generative AI, but a single invocation of a foundation model (FM) is not enough because I need to interact with other systems. To do that, I use an agent.

In the Amazon Bedrock console, I choose Agents from the navigation pane and then Create Agent. I enter a name for the agent (customer-feedback) and a description. Using the new interface, I proceed and create the agent without providing additional information at this stage.

Console screenshot.

I am now presented with the Agent builder, the place where I can access and edit the overall configuration of an agent. In the Agent resource role, I leave the default setting as Create and use a new service role so that the AWS Identity and Access Management (IAM) role assumed by the agent is automatically created for me. For the model, I select Anthropic and Claude 3 Sonnet.

Console screenshot.

In Instructions for the Agent, I provide clear and specific instructions for the task the agent has to perform. Here, I can also specify the style and tone I want the agent to use when replying. For my use case, I enter:

Help reply to customer feedback emails with a solution tailored to the customer account settings.

In Additional settings, I select Enabled for User input so that the agent can ask for additional details when it does not have enough information to respond. Then, I choose Save to update the configuration of the agent.

I now choose Add in the Action groups section. Action groups are the way agents can interact with external systems to gather more information or perform actions. I enter a name (retrieve-customer-settings) and a description for the action group:

Retrieve customer settings including customer ID.

The description is optional but, when provided, is passed to the model to help choose when to use this action group.

Console screenshot.

In Action group type, I select Define with function details so that I only need to specify functions and their parameters. The other option here (Define with API schemas) corresponds to the previous way of configuring action groups using an API schema.

Action group functions can be associated to a Lambda function call or configured to return control to the user or application invoking the agent so that they can provide a response to the function. The option to return control is useful for four main use cases:

  • When it’s easier to call an API from an existing application (for example, the one invoking the agent) than building a new Lambda function with the correct authentication and network configurations as required by the API
  • When the duration of the task goes beyond the maximum Lambda function timeout of 15 minutes so that I can handle the task with an application running in containers or virtual servers or use a workflow orchestration such as AWS Step Functions
  • When I have time-consuming actions because, with the return of control, the agent doesn’t wait for the action to complete before proceeding to the next step, and the invoking application can run actions asynchronously in the background while the orchestration flow of the agent continues
  • When I need a quick way to mock the interaction with an API during the development and testing and of an agent

In Action group invocation, I can specify the Lambda function that will be invoked when this action group is identified by the model during orchestration. I can ask the console to quickly create a new Lambda function, to select an existing Lambda function, or return control so that the user or application invoking the agent will ask for details to generate a response. I select Return Control to show how that works in the console.

Console screenshot.

I configure the first function of the action group. I enter a name (retrieve-customer-settings-from-crm) and the following description for the function:

Retrieve customer settings from CRM including customer ID using the customer email in the sender/from fields of the email.

Console screenshot.

In Parameters, I add email with Customer email as the description. This is a parameter of type String and is required by this function. I choose Add to complete the creation of the action group.

Because, for my use case, I expect many customers to have issues when logging in, I add another action group (named check-login-status) with the following description:

Check customer login status.

This time, I select the option to create a new Lambda function so that I can handle these requests in code.

For this action group, I configure a function (named check-customer-login-status-in-login-system) with the following description:

Check customer login status in login system using the customer ID from settings.

In Parameters, I add customer_id, another required parameter of type String. Then, I choose Add to complete the creation of the second action group.

When I open the configuration of this action group, I see the name of the Lambda function that has been created in my account. There, I choose View to open the Lambda function in the console.

Console screenshot.

In the Lambda console, I edit the starting code that has been provided and implement my business case:

import json

def lambda_handler(event, context):
    print(event)
    
    agent = event['agent']
    actionGroup = event['actionGroup']
    function = event['function']
    parameters = event.get('parameters', [])

    # Execute your business logic here. For more information,
    # refer to: https://docs.aws.amazon.com/bedrock/latest/userguide/agents-lambda.html
    if actionGroup == 'check-login-status' and function == 'check-customer-login-status-in-login-system':
        response = {
            "status": "unknown"
        }
        for p in parameters:
            if p['name'] == 'customer_id' and p['type'] == 'string' and p['value'] == '12345':
                response = {
                    "status": "not verified",
                    "reason": "the email address has not been verified",
                    "solution": "please verify your email address"
                }
    else:
        response = {
            "error": "Unknown action group {} or function {}".format(actionGroup, function)
        }
    
    responseBody =  {
        "TEXT": {
            "body": json.dumps(response)
        }
    }

    action_response = {
        'actionGroup': actionGroup,
        'function': function,
        'functionResponse': {
            'responseBody': responseBody
        }

    }

    dummy_function_response = {'response': action_response, 'messageVersion': event['messageVersion']}
    print("Response: {}".format(dummy_function_response))

    return dummy_function_response

I choose Deploy in the Lambda console. The function is configured with a resource-based policy that allows Amazon Bedrock to invoke the function. For this reason, I don’t need to update the IAM role used by the agent.

I am ready to test the agent. Back in the Amazon Bedrock console, with the agent selected, I look for the Test Agent section. There, I choose Prepare to prepare the agent and test it with the latest changes.

As input to the agent, I provide this sample email:

From: [email protected]

Subject: Problems logging in

Hi, when I try to log into my account, I get an error and cannot proceed further. Can you check? Thank you, Danilo

In the first step, the agent orchestration decides to use the first action group (retrieve-customer-settings) and function (retrieve-customer-settings-from-crm). This function is configured to return control, and in the console, I am asked to provide the output of the action group function. The customer email address is provided as the input parameter.

Console screenshot.

To simulate an interaction with an application, I reply with a JSON syntax and choose Submit:

{ "customer id": 12345 }

In the next step, the agent has the information required to use the second action group (check-login-status) and function (check-customer-login-status-in-login-system) to call the Lambda function. In return, the Lambda function provides this JSON payload:

{
  "status": "not verified",
  "reason": "the email address has not been verified",
  "solution": "please verify your email address"
}

Using this content, the agent can complete its task and suggest the correct solution for this customer.

Console screenshot.

I am satisfied with the result, but I want to know more about what happened under the hood. I choose Show trace where I can see the details of each step of the agent orchestration. This helps me understand the agent decisions and correct the configurations of the agent groups if they are not used as I expect.

Console screenshot.

Things to know
You can use the new simplified experience to create and manage Agents for Amazon Bedrock in the US East (N. Virginia) and US West (Oregon) AWS Regions.

You can now create an agent without having to specify an API schema or provide a Lambda function for the action groups. You just need to list the parameters that the action group needs. When invoking the agent, you can choose to return control with the details of the operation to perform so that you can handle the operation in your existing applications or if the duration is longer than the maximum Lambda function timeout.

CloudFormation support for Agents for Amazon Bedrock has been released recently and is now being updated to support the new simplified syntax.

Amazon Bedrock model evaluation is now generally available

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/amazon-bedrock-model-evaluation-is-now-generally-available/

The Amazon Bedrock model evaluation capability that we previewed at AWS re:Invent 2023 is now generally available. This new capability helps you to incorporate Generative AI into your application by giving you the power to select the foundation model that gives you the best results for your particular use case. As my colleague Antje explained in her post (Evaluate, compare, and select the best foundation models for your use case in Amazon Bedrock):

Model evaluations are critical at all stages of development. As a developer, you now have evaluation tools available for building generative artificial intelligence (AI) applications. You can start by experimenting with different models in the playground environment. To iterate faster, add automatic evaluations of the models. Then, when you prepare for an initial launch or limited release, you can incorporate human reviews to help ensure quality.

We received a lot of wonderful and helpful feedback during the preview and used it to round-out the features of this new capability in preparation for today’s launch — I’ll get to those in a moment. As a quick recap, here are the basic steps (refer to Antje’s post for a complete walk-through):

Create a Model Evaluation Job – Select the evaluation method (automatic or human), select one of the available foundation models, choose a task type, and choose the evaluation metrics. You can choose accuracy, robustness, and toxicity for an automatic evaluation, or any desired metrics (friendliness, style, and adherence to brand voice, for example) for a human evaluation. If you choose a human evaluation, you can use your own work team or you can opt for an AWS-managed team. There are four built-in task types, as well as a custom type (not shown):

After you select the task type you choose the metrics and the datasets that you want to use to evaluate the performance of the model. For example, if you select Text classification, you can evaluate accuracy and/or robustness with respect to your own dataset or a built-in one:

As you can see above, you can use a built-in dataset, or prepare a new one in JSON Lines (JSONL) format. Each entry must include a prompt and can include a category. The reference response is optional for all human evaluation configurations and for some combinations of task types and metrics for automatic evaluation:

{
  "prompt" : "Bobigny is the capitol of",
  "referenceResponse" : "Seine-Saint-Denis",
  "category" : "Capitols"
}

You (or your local subject matter experts) can create a dataset that uses customer support questions, product descriptions, or sales collateral that is specific to your organization and your use case. The built-in datasets include Real Toxicity, BOLD, TREX, WikiText-2, Gigaword, BoolQ, Natural Questions, Trivia QA, and Women’s Ecommerce Clothing Reviews. These datasets are designed to test specific types of tasks and metrics, and can be chosen as appropriate.

Run Model Evaluation Job – Start the job and wait for it to complete. You can review the status of each of your model evaluation jobs from the console, and can also access the status using the new GetEvaluationJob API function:

Retrieve and Review Evaluation Report – Get the report and review the model’s performance against the metrics that you selected earlier. Again, refer to Antje’s post for a detailed look at a sample report.

New Features for GA
With all of that out of the way, let’s take a look at the features that were added in preparation for today’s launch:

Improved Job Management – You can now stop a running job using the console or the new model evaluation API.

Model Evaluation API – You can now create and manage model evaluation jobs programmatically. The following functions are available:

  • CreateEvaluationJob – Create and run a model evaluation job using parameters specified in the API request including an evaluationConfig and an inferenceConfig.
  • ListEvaluationJobs – List model evaluation jobs, with optional filtering and sorting by creation time, evaluation job name, and status.
  • GetEvaluationJob – Retrieve the properties of a model evaluation job, including the status (InProgress, Completed, Failed, Stopping, or Stopped). After the job has completed, the results of the evaluation will be stored at the S3 URI that was specified in the outputDataConfig property supplied to CreateEvaluationJob.
  • StopEvaluationJob – Stop an in-progress job. Once stopped, a job cannot be resumed, and must be created anew if you want to rerun it.

This model evaluation API was one of the most-requested features during the preview. You can use it to perform evaluations at scale, perhaps as part of a development or testing regimen for your applications.

Enhanced Security – You can now use customer-managed KMS keys to encrypt your evaluation job data (if you don’t use this option, your data is encrypted using a key owned by AWS):

Access to More Models – In addition to the existing text-based models from AI21 Labs, Amazon, Anthropic, Cohere, and Meta, you now have access to Claude 2.1:

After you select a model you can set the inference configuration that will be used for the model evaluation job:

Things to Know
Here are a couple of things to know about this cool new Amazon Bedrock capability:

Pricing – You pay for the inferences that are performed during the course of the model evaluation, with no additional charge for algorithmically generated scores. If you use human-based evaluation with your own team, you pay for the inferences and $0.21 for each completed task — a human worker submitting an evaluation of a single prompt and its associated inference responses in the human evaluation user interface. Pricing for evaluations performed by an AWS managed work team is based on the dataset, task types, and metrics that are important to your evaluation. For more information, consult the Amazon Bedrock Pricing page.

Regions – Model evaluation is available in the US East (N. Virginia) and US West (Oregon) AWS Regions.

Import custom models in Amazon Bedrock (preview)

Post Syndicated from Danilo Poccia original https://aws.amazon.com/blogs/aws/import-custom-models-in-amazon-bedrock-preview/

With Amazon Bedrock, you have access to a choice of high-performing foundation models (FMs) from leading artificial intelligence (AI) companies that make it easier to build and scale generative AI applications. Some of these models provide publicly available weights that can be fine-tuned and customized for specific use cases. However, deploying customized FMs in a secure and scalable way is not an easy task.

Starting today, Amazon Bedrock adds in preview the capability to import custom weights for supported model architectures (such as Meta Llama 2, Llama 3, and Mistral) and serve the custom model using On-Demand mode. You can import models with weights in Hugging Face safetensors format from Amazon SageMaker and Amazon Simple Storage Service (Amazon S3).

In this way, you can use Amazon Bedrock with existing customized models such as Code Llama, a code-specialized version of Llama 2 that was created by further training Llama 2 on code-specific datasets, or use your data to fine-tune models for your own unique business case and import the resulting model in Amazon Bedrock.

Let’s see how this works in practice.

Bringing a custom model to Amazon Bedrock
In the Amazon Bedrock console, I choose Imported models from the Foundation models section of the navigation pane. Now, I can create a custom model by importing model weights from an Amazon Simple Storage Service (Amazon S3) bucket or from an Amazon SageMaker model.

I choose to import model weights from an S3 bucket. In another browser tab, I download the MistralLite model from the Hugging Face website using this pull request (PR) that provides weights in safetensors format. The pull request is currently Ready to merge, so it might be part of the main branch when you read this. MistralLite is a fine-tuned Mistral-7B-v0.1 language model with enhanced capabilities of processing long context up to 32K tokens.

When the download is complete, I upload the files to an S3 bucket in the same AWS Region where I will import the model. Here are the MistralLite model files in the Amazon S3 console:

Console screenshot.

Back at the Amazon Bedrock console, I enter a name for the model and keep the proposed import job name.

Console screenshot.

I select Model weights in the Model import settings and browse S3 to choose the location where I uploaded the model weights.

Console screenshot.

To authorize Amazon Bedrock to access the files on the S3 bucket, I select the option to create and use a new AWS Identity and Access Management (IAM) service role. I use the View permissions details link to check what will be in the role. Then, I submit the job.

About ten minutes later, the import job is completed.

Console screenshot.

Now, I see the imported model in the console. The list also shows the model Amazon Resource Name (ARN) and the creation date.

Console screenshot.

I choose the model to get more information, such as the S3 location of the model files.

Console screenshot.

In the model detail page, I choose Open in playground to test the model in the console. In the text playground, I type a question using the prompt template of the model:

<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>

The MistralLite imported model is quick to reply and describe some of those challenges.

Console screenshot.

In the playground, I can tune responses for my use case using configurations such as temperature and maximum length or add stop sequences specific to the imported model.

To see the syntax of the API request, I choose the three small vertical dots at the top right of the playground.

Console screenshot.

I choose View API syntax and run the command using the AWS Command Line Interface (AWS CLI):

aws bedrock-runtime invoke-model \
--model-id arn:aws:bedrock:us-east-1:123412341234:imported-model/a82bkefgp20f \
--body "{\"prompt\":\"<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>\",\"max_tokens\":512,\"top_k\":200,\"top_p\":0.9,\"stop\":[],\"temperature\":0.5}" \
--cli-binary-format raw-in-base64-out \
--region us-east-1 \
invoke-model-output.txt

The output is similar to what I got in the playground. As you can see, for imported models, the model ID is the ARN of the imported model. I can use the model ID to invoke the imported model with the AWS CLI and AWS SDKs.

Things to know
You can bring your own weights for supported model architectures to Amazon Bedrock in the US East (N. Virginia) AWS Region. The model import capability is currently available in preview.

When using custom weights, Amazon Bedrock serves the model with On-Demand mode, and you only pay for what you use with no time-based term commitments. For detailed information, see Amazon Bedrock pricing.

The ability to import models is managed using AWS Identity and Access Management (IAM), and you can allow this capability only to the roles in your organization that need to have it.

With this launch, it’s now easier to build and scale generative AI applications using custom models with security and privacy built in.

Amazon Titan Image Generator and watermark detection API are now available in Amazon Bedrock

Post Syndicated from Antje Barth original https://aws.amazon.com/blogs/aws/amazon-titan-image-generator-and-watermark-detection-api-are-now-available-in-amazon-bedrock/

During AWS re:Invent 2023, we announced the preview of Amazon Titan Image Generator, a generative artificial intelligence (generative AI) foundation model (FM) that you can use to quickly create and refine realistic, studio-quality images using English natural language prompts.

I’m happy to share that Amazon Titan Image Generator is now generally available in Amazon Bedrock, giving you an easy way to build and scale generative AI applications with new image generation and image editing capabilities, including instant customization of images.

In my previous post, I also mentioned that all images generated by Titan Image Generator contain an invisible watermark, by default, which is designed to help reduce the spread of misinformation by providing a mechanism to identify AI-generated images.

I’m excited to announce that watermark detection for Titan Image Generator is now generally available in the Amazon Bedrock console. Today, we’re also introducing a new DetectGeneratedContent API (preview) in Amazon Bedrock that checks for the existence of this watermark and helps you confirm whether an image was generated by Titan Image Generator.

Let me show you how to get started with these new capabilities.

Instant image customization using Amazon Titan Image Generator
You can now generate new images of a subject by providing up to five reference images. You can create the subject in different scenes while preserving its key features, transfer the style from the reference images to new images, or mix styles from multiple reference images. All this can be done without additional prompt engineering or fine-tuning of the model.

For this demo, I prompt Titan Image Generator to create an image of a “parrot eating a banana.” In the first attempt, I use Titan Image Generator to create this new image without providing a reference image.

Note: In the following code examples, I’ll use the AWS SDK for Python (Boto3) to interact with Amazon Bedrock. You can find additional code examples for C#/.NET, Go, Java, and PHP in the Bedrock User Guide.

import boto3
import json

bedrock_runtime = boto3.client(service_name="bedrock-runtime")

body = json.dumps(
    {
        "taskType": "TEXT_IMAGE",
        "textToImageParams": {
            "text": "parrot eating a banana",   
        },
        "imageGenerationConfig": {
            "numberOfImages": 1,   
            "quality": "premium", 
            "height": 768,
            "width": 1280,
            "cfgScale": 10, 
            "seed": 42
        }
    }
)
response = bedrock_runtime.invoke_model(
    body=body, 
    modelId="amazon.titan-image-generator-v1",
    accept="application/json", 
    contentType="application/json"
)

You can display the generated image using the following code.

import io
import base64
from PIL import Image

response_body = json.loads(response.get("body").read())

images = [
    Image.open(io.BytesIO(base64.b64decode(base64_image)))
    for base64_image in response_body.get("images")
]

for img in images:
    display(img)

Here’s the generated image:

Image of a parrot eating a banana generated by Amazon Titan Image Generator

Then, I use the new instant image customization capability with the same prompt, but now also providing the following two reference images. For easier comparison, I’ve resized the images, added a caption, and plotted them side by side.

Reference images for Amazon Titan Image Generator

Here’s the code. The new instant customization is available through the IMAGE_VARIATION task:

# Import reference images
image_path_1 = "parrot-cartoon.png"
image_path_2 = "bird-sketch.png"

with open(image_path_1, "rb") as image_file:
    input_image_1 = base64.b64encode(image_file.read()).decode("utf8")

with open(image_path_2, "rb") as image_file:
    input_image_2 = base64.b64encode(image_file.read()).decode("utf8")

# ImageVariationParams options:
#   text: Prompt to guide the model on how to generate variations
#   images: Base64 string representation of a reference image, up to 5 images are supported
#   similarityStrength: Parameter you can tune to control similarity with reference image(s)

body = json.dumps(
    {
        "taskType": "IMAGE_VARIATION",
        "imageVariationParams": {
            "text": "parrot eating a banana",  # Required
            "images": [input_image_1, input_image_2],  # Required 1 to 5 images
            "similarityStrength": 0.7,  # Range: 0.2 to 1.0
        },
        "imageGenerationConfig": {
            "numberOfImages": 1,
            "quality": "premium",
            "height": 768,
            "width": 1280,
            "cfgScale": 10,
            "seed": 42
        }
    }
)

response = bedrock_runtime.invoke_model(
    body=body, 
    modelId="amazon.titan-image-generator-v1",
    accept="application/json", 
    contentType="application/json"
)

Once again, I’ve resized the generated image, added a caption, and plotted it side by side with the originally generated image. Amazon Titan Image Generator instance customization results

You can see how the parrot in the second image that has been generated using the instant image customization capability resembles in style the combination of the provided reference images.

Watermark detection for Amazon Titan Image Generator
All Amazon Titan FMs are built with responsible AI in mind. They detect and remove harmful content from data, reject inappropriate user inputs, and filter model outputs. As content creators create realistic-looking images with AI, it’s important to promote responsible development of this technology and reduce the spread of misinformation. That’s why all images generated by Titan Image Generator contain an invisible watermark, by default. Watermark detection is an innovative technology, and Amazon Web Services (AWS) is among the first major cloud providers to widely release built-in watermarks for AI image outputs.

Titan Image Generator’s new watermark detection feature is a mechanism that allows you to identify images generated by Amazon Titan. These watermarks are designed to be tamper-resistant, helping increase transparency around AI-generated content as these capabilities continue to advance.

Watermark detection using the console
Watermark detection is generally available in the Amazon Bedrock console. You can upload an image to detect watermarks embedded in images created by Titan Image Generator, including those generated by the base model and any customized versions. If you upload an image that was not created by Titan Image Generator, then the model will indicate that a watermark has not been detected.

The watermark detection feature also comes with a confidence score. The confidence score represents the confidence level in watermark detection. In some cases, the detection confidence may be low if the original image has been modified. This new capability enables content creators, news organizations, risk analysts, fraud detection teams, and others to better identify and mitigate misleading AI-generated content, promoting transparency and responsible AI deployment across organizations.

Watermark detection using the API (preview)
In addition to watermark detection using the console, we’re introducing a new DetectGeneratedContent API (preview) in Amazon Bedrock that checks for the existence of this watermark and helps you confirm whether an image was generated by Titan Image Generator. Let’s see how this works.

For this demo, let’s check if the image of the green iguana I showed in the Titan Image Generator preview post was indeed generated by the model.

Green iguana generated by Amazon Titan Image Generator

I define the imports, set up the Amazon Bedrock boto3 runtime client, and base64-encode the image. Then, I call the DetectGeneratedContent API by specifying the foundation model and providing the encoded image.

import boto3
import json
import base64

bedrock_runtime = boto3.client(service_name="bedrock-runtime")

image_path = "green-iguana.png"

with open(image_path, "rb") as image_file:
    input_image_iguana = image_file.read()

response = bedrock_runtime.detect_generated_content(
    foundationModelId = "amazon.titan-image-generator-v1",
    content = {
        "imageContent": { "bytes": input_image_iguana }
    }
)

Let’s check the response.

response.get("detectionResult")
'GENERATED'
response.get("confidenceLevel")
'HIGH'

The response GENERATED with the confidence level HIGH confirms that Amazon Bedrock detected a watermark generated by Titan Image Generator.

Now, let’s check another image I generated using Stable Diffusion XL 1.0 on Amazon Bedrock. In this case, a “meerkat facing the sunset.”

Meerkat facing the sunset

I call the API again, this time with the image of the meerkat.

image_path = "meerkat.png"

with open(image_path, "rb") as image_file:
    input_image_meerkat = image_file.read()

response = bedrock_runtime.detect_generated_content(
    foundationModelId = "amazon.titan-image-generator-v1",
    content = {
        "imageContent": { "bytes": input_image_meerkat }
    }
)

response.get("detectionResult")
'NOT_GENERATED'

And indeed, the response NOT_GENERATED tells me that there was no watermark by Titan Image Generator detected, and therefore, the image most likely wasn’t generated by the model.

Using Amazon Titan Image Generator and watermark detection in the console
Here’s a short demo of how to get started with Titan Image Generator and the new watermark detection feature in the Amazon Bedrock console, put together by my colleague Nirbhay Agarwal.

Availability
Amazon Titan Image Generator, the new instant customization capabilities, and watermark detection in the Amazon Bedrock console are available today in the AWS Regions US East (N. Virginia) and US West (Oregon). Check the full Region list for future updates. The new DetectGeneratedContent API in Amazon Bedrock is available today in public preview in the AWS Regions US East (N. Virginia) and US West (Oregon).
