Today, AWS announced support for response streaming in Amazon API Gateway to significantly improve the responsiveness of your REST APIs by progressively streaming response payloads back to the client. With this new capability, you can use streamed responses to enhance user experience when building LLM-driven applications (such as AI agents and chatbots), improve time-to-first-byte (TTFB) performance for web and mobile applications, stream large files, and perform long-running operations while reporting incremental progress using protocols such as server-sent events (SSE).
In this post you will learn about this new capability, the challenges it addresses, and how to use response streaming to improve the responsiveness of your applications.
Consider this scenario – you’re running an AI-powered agentic application that uses an Amazon Bedrock foundation model. Your users interact with the application through an API, asking complex questions that…
