- **Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking generally available
(GA)**: Released two new audio-to-audio models for real-time voice
applications using the Live API:

- **Gemini 3.8 Live** ([`gemini-3.8-live`](https://ai.google.dev/gemini-api/docs/models/gemini-3.8-live)): The default option for most low-latency voice agent experiences and real-time dialogue without reasoning delays. Features interleaved reasoning, default asynchronous function calling, and full session client content updates.
- **Gemini 3.8 Live Extended Thinking** ([`gemini-3.8-live-extended-thinking`](https://ai.google.dev/gemini-api/docs/models/gemini-3.8-live-extended-thinking)): High-reasoning audio-to-audio model supporting background reasoning during live audio interactions, recommended when higher background reasoning is required.
