Due to shut down on 17 November 2026, so voice agent builders should go straight to Gemini 3.8 Live.

Kenning's take

What it does

Gemini 3.1 Flash Live is an audio-to-audio model for real-time voice conversations. It powered Gemini Live and Search Live and was offered to developers through the Live API for building voice agents. Google now labels it a legacy preview and recommends Gemini 3.8 Live; the preview is due to shut down on 17 November 2026.

• Real-time spoken dialogue
• Function calling during conversation
• Better handling of tone, pitch and pace
• Multilingual voice
• SynthID watermark on audio

Who it suits. Developers building voice agents and people using Gemini Live.
