Gemini 3.8 Live
Strong value for high-volume usage.
Overview
Gemini 3.8 Live has been available since 15 September 2026 in the Gemini Live API and Google AI Studio. It is an audio-to-audio model built for low-latency voice agents: it holds a spoken conversation, understands what the camera shows, switches language mid-sentence among 97 languages and runs tool calls in the background without breaking the conversation. Google presents it as the default choice for voice; an Extended Thinking variant exists for exchanges that need multi-step reasoning. Pricing: $0.75 / $4.50 per million text tokens, $3 / $12 per million audio tokens, about $1.38 per hour of conversation according to Google. 131,072-token context. It supports neither prompt caching nor structured output.
