Plain-English overview
What Gemini 3.8 Live actually is
Gemini 3.8 Live can discuss what a user says or shows on camera and call tools during a conversation. Unlike Gemini 3.8 Flash, which returns text, Live is built for spoken interaction.
Choose this version for everyday voice assistants. Its reasoning is interleaved with conversation, without an adjustable thinking level. Extended Thinking is a separate model for more involved tasks.
