Google launches Gemini 3.8 Live and Live Extended Thinking voice models
Google announced (Sept 15) Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking—its most advanced live dialogue / speech-to-speech models yet, with upgrades in conversational intelligence, parallel reasoning, near–real-time visual grounding, mid-conversation switching across 97 languages, and background tool/API execution while dialogue continues. 3.8 Live Extended Thinking ranks #1 on Artificial Analysis’ Speech-to-Speech Quality Index (82.6) and leads agentic voice benchmarks (68.6% on τ-Voice; 35.1% on Sierra τ-Voice-banking), with live progress narration for multi-step tasks. Both models roll out today via the Gemini API and Google AI Studio; 3.8 Live reaches Search Live, while Extended Thinking reaches Gemini Live plus Google AI Pro/Ultra Workspace Docs and all Google AI subscribers in Gmail and Keep (enterprise private preview in Gemini Enterprise). Audio is SynthID-watermarked. Distinct from Gemini 3.8 Flash Cyber, from the Gemini Windows desktop app, and from OpenAI GPT-Live-1.
