A company wants an AI assistant that can evaluate specific data sources, call external APIs, generate multiple response options, and then compare and prioritize those options. Which Amazon Bedrock capability best fits these requirements?

Amazon Bedrock Agents are designed to orchestrate complex tasks by breaking them down into smaller steps. They can invoke APIs, retrieve information from knowledge bases, and use reasoning to generate and refine responses, making them ideal for scenarios requiring multi-step processing, external tool use, and response prioritization. Prompt Management is a broader concept for organizing and optimizing prompts, not a specific execution capability. Response streaming is a feature for delivering responses incrementally, not for task orchestration. Knowledge Bases provide retrieval augmented generation (RAG) capabilities but do not inherently handle multi-step reasoning, API calls, or response prioritization on their own; they serve as a data source for agents or models.
