Build and orchestrate generative AI applications with Amazon Bedrock and Step Functions

The following code example shows how to build and orchestrate generative AI applications with Amazon Bedrock and Step Functions.

Python
SDK for Python (Boto3)

The Amazon Bedrock Serverless Prompt Chaining scenario demonstrates how AWS Step Functions, Amazon Bedrock, and https://docs.aws.amazon.com/bedrock/latest/userguide/agents.html can be used to build and orchestrate complex, serverless, and highly scalable generative AI applications. It contains the following working examples:

  • Write an analysis of a given novel for a literature blog. This example illustrates a simple, sequential chain of prompts.

  • Generate a short story about a given topic. This example illustrates how the AI can iteratively process a list of items that it previously generated.

  • Create an itinerary for a weekend vacation to a given destination. This example illustrates how to parallelize multiple distinct prompts.

  • Pitch movie ideas to a human user acting as a movie producer. This example illustrates how to parallelize the same prompt with different inference parameters, how to backtrack to a previous step in the chain, and how to include human input as part of the workflow.

  • Plan a meal based on ingredients the user has at hand. This example illustrates how prompt chains can incorporate two distinct AI conversations, with two AI personas engaging in a debate with each other to improve the final outcome.

  • Find and summarize today's highest trending GitHub repository. This example illustrates chaining multiple AI agents that interact with external APIs.
