Gemini 3.8 Live is a natively multimodal audio model built for cost-efficient, high-volume voice interactions. It processes visual inputs in near real time, automatically detects and transitions between 97 supported languages mid-conversation, and executes tool calls in the background without interrupting dialogue. Based on Gemini 3 Pro, it delivers fluid conversational intelligence with visual grounding.
