About Gemini 3.8 Live

Google started releasing Gemini 3.8 Live on 15 September 2026, a model for live spoken conversation. Google says it is built for scale and cost efficiency. It accepts audio, images, video and text and replies in audio or text, handling visual input in near real time during a conversation.

Main features

  • Voice conversation: speech-to-speech dialogue designed for voice agents.
  • Multilingual: detects and switches between 97 supported languages mid-conversation.
  • Tool features: function calling, Search grounding and thinking are supported; caching, structured outputs, code execution and batch are not.
  • Limits: it accepts 131,072 tokens in and returns up to 65,536 tokens out.

Who it serves

Developers through the Gemini API and Google AI Studio, Gemini Enterprise in private preview, and consumers through Search Live.
