Gemini 3.8 Live Extended Thinking

by Google

Gemini 3.8 Live Extended Thinking is the higher-reasoning member of Google's Gemini 3.8 Live audio family, announced on September 15, 2026 and built for high-complexity tasks that need multi-step reasoning during a live voice conversation. It takes text, images, audio and video as input and returns text and audio, with a 131,072-token input limit and 65,536-token output limit. The model reasons in the background while it keeps talking, using natural verbal cues such as "Let me check that" and narrating progress on multi-step tasks. Background reasoning is set with thinking levels of low, medium or high, and function calling is asynchronous only, so tools keep running while audio continues to stream; search grounding is also supported. Google says it handles 97 languages, including switching language mid-conversation. On Google's numbers it scores 82.6 on Artificial Analysis' Speech to Speech Quality Index (the top overall rank at launch), 68.6% on the tau-Voice agentic task benchmark, 35.1% on Sierra's tau-Voice banking benchmark and 97.7% on Big Bench Audio. It fits voice agents and assistants that must complete complex, tool-heavy workflows without breaking conversational flow.
