Is the python ag_ui_langgraph "thread" safe?

[marksmithson]

(Yes FastAPI uses asyncio, and uses a single thread, so not strictly thread safety, rather safe for concurrent use)

Looking at the Python FastAPI endpoint , this takes a LangGraphAgent as an argument.

This means that the agent is shared across all requests. The agent implementation appears to store state for each request in self.active_run.

Within the run function it calls await self.graph.aget_state(config) potentially yielding to another request

Doesn't this mean that concurrent requests to FastAPI may change this variable for different requests?

Or have I misunderstood how asyncio works in this case? (newish to python so not impossible)
