For a voice agent it handles everything around the models: realtime transport, turn detection, interruption handling, telephony, and deployment on LiveKit Cloud.
LiveKit Inference is the managed way to reach the models themselves from inside LiveKit Agents.
You name a model instead of holding an account with each provider, LiveKit runs it on its own infrastructure to keep the round trip short, and usage and rate limits are handled through LiveKit Cloud.
