To make Vercel AI SDK chat streams resumable, you persist AI chat responses in durable streams. This allows you to resume conversations and continue in-flight generations seamlessly after a browser refresh.

Durable streaming writes AI chat output to persistent streams that can be replayed or tail-tracked. It prevents the loss of generation progress during a web page reload by securely storing the response data.

Yes, durable streams integrate directly with the Vercel AI SDK useChat() hook in web apps. This integration enables resumable conversations across page reloads without losing active generation progress.

You secure write URLs and credentials by using server-side read proxy endpoints. This read proxy hides your write URLs while still allowing clients to safely resume conversations.

Yes, durable streaming works in serverless environments by supporting await mode alongside immediate response mode. Await mode is specifically designed to handle the execution constraints of serverless computing platforms.

Use immediate mode for instant response delivery or await mode for serverless environments. Await mode ensures the stream completes safely within serverless execution limits, while immediate mode prioritizes instant delivery.
