## Live API model support

LiveKit supports both Gemini Live API on both Gemini Developer API as well as Vertex AI. However, be aware they have slightly different behavior and use different model names.

The following models are supported by Gemini Developer API:

- gemini-3.1-flash-live-preview
- gemini-2.5-flash-native-audio-preview-09-2025
- gemini-2.5-flash-native-audio-preview-12-2025

And these on Vertex AI:

- gemini-live-2.5-flash-native-audio
