# Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking generally available (GA)

By Steven Van · 2026-09-15

Google's Live API gets two GA audio-to-audio models: a low-latency default and an extended-thinking option for heavier reasoning.

Two audio-to-audio models for the Live API are now generally available in [Gemini](<https://creatorstoolbox.com/tools/gemini>). Both are built for real-time voice applications rather than text chat.

- **Gemini 3.8 Live** (gemini-3.8-live) is the default model for low-latency voice agents and real-time dialogue without reasoning delays. It uses interleaved reasoning, asynchronous function calling by default, and full session client content updates.

- **Gemini 3.8 Live Extended Thinking** (gemini-3.8-live-extended-thinking) supports background reasoning during live audio interactions, for use cases that need higher reasoning quality than the default model provides.

Details on architecture and setup are in Google's [Live API thinking guide](<https://ai.google.dev/gemini-api/docs/live-api/thinking>).
