Enhancing prompts with role assignment

In this exercise, you'll improve a basic question about Amazon Bedrock by assigning Claude the role of an AWS expert. You'll learn to enhance your prompt and handle the model's response to ensure the output is correctly formatted and error-free.

The json library and bedrock client have been pre-imported.

Exercise instructions

Specify the role of an AWS expert as part of the prompt.
Parse the response body to extract the output.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Format the prompt with role and required Claude format
prompt = '____'

request_body = json.dumps({"anthropic_version": "bedrock-2023-05-31", "max_tokens": 100, 
                           "messages": [{"role": "user", "content": prompt}]})
response = bedrock.invoke_model(modelId='anthropic.claude-3-5-sonnet-20240620-v1:0', 
                                body=request_body)

# Extract completion from response
output = json.loads(response['body'].____)['content'][0]['text'] # Parse JSON and get completion       
      
print(output)

Learn the fundamentals of Amazon Bedrock, AWS's fully managed foundation model service. Start with basic setup and authentication, explore available foundation models like Claude and Titan, and master essential API interactions. This chapter covers setting up a development environment, choosing appropriate models for a use case, and implementing proper API request handling, including streaming responses and error management.

Exercise 1: Accessing Amazon Bedrock Exercise 2: Initializing the Bedrock client Exercise 3: Retrieving Bedrock model details Exercise 4: Selecting a foundation model Exercise 5: Using the correct model in Bedrock Exercise 6: Generating text in Bedrock

In this chapter, you'll progress through three key lessons. Starting with the basics of text generation and response handling, you'll then advance to sophisticated prompt engineering techniques like few-shot learning and structured outputs. The final lesson covers model parameter optimization, teaching learners to fine-tune settings like temperature and token limits for optimal results. Each lesson builds upon the previous, moving from fundamental API interactions to advanced parameter control for specific use cases.

In this chapter, you’ll build robust and responsible applications with Amazon Bedrock, moving beyond basic API interactions. Starting with conversational AI, you’ll master state management and context handling to create coherent chat experiences. You’ll then explore advanced prompting techniques, learning how to generate diverse content types while maintaining consistent style and tone. The chapter covers critical production aspects like error handling, rate limiting, and efficient response processing. Finally, you will implement ethical guardrails and safety measures, ensuring your AI applications are both powerful and responsible.
