FAQPage Schema
How do I build a streaming chat backend with FastAPI?

You can build a streaming chat backend by subclassing ChatKitServer and exposing a FastAPI endpoint that streams responses. It uses AsyncIterator and StreamingResponse to handle real-time chat sessions and thread management asynchronously.

Does ChatKit work with the OpenAI Agents SDK for real-time conversations?

Yes, ChatKit works with the OpenAI Agents SDK to enable real-time conversations. The backend integrates with the SDK to stream assistant messages and progress events asynchronously to a ChatKit-integrated React frontend.

What is the best way to manage chat threads in an asynchronous streaming server?

The best way to manage chat threads in an asynchronous streaming server is using a Postgres-backed thread store. This approach provides modular integration and persistent thread management for streaming AI responses.

How do I stream AI responses to a React frontend using FastAPI?

You stream AI responses to a React frontend using FastAPI by implementing SSE-like streaming of assistant messages. The server uses AsyncIterator and StreamingResponse to push real-time progress events and messages to ChatKit-integrated frontends.

Can I add custom endpoints to a ChatKit streaming server?

Yes, you can add custom endpoints to a ChatKit streaming server. The backend provides expandable FastAPI endpoints for extensible task handling, allowing you to integrate additional logic alongside the OpenAI Agents SDK.
