LiveKit and TheRouter
LiveKit offers different plugins for Chat Completions and Responses. TheRouter's HTTP Chat Completions endpoint has been tested with the official OpenAI client. A complete LiveKit voice pipeline and the LiveKit Responses WebSocket transport have not been verified against TheRouter.
For a Chat Completions integration, check that your LiveKit plugin version allows a custom OpenAI-compatible base URL, configure https://api.therouter.ai/v1 with a server-side TheRouter key, and test model, streaming, tool and audio behavior independently. A working text request does not establish voice or realtime support.
Read LiveKit's OpenAI plugin documentation, the tested Python API example, and the model catalog.
