The InvokeWithResponseStream API lets functions send partial responses incrementally to clients, reducing time-to-first-byte latency. This is particularly useful for LLM-based applications and web/mobile apps. Streaming supports payloads up to 200 MB, works with Node.js and custom runtimes, and can be accessed via supported AWS SDKs or Amazon API Gateway REST APIs. Billing applies per bytes streamed beyond the first 6 MB. ## Full article daily.dev links to this article rather than hosting it.
