Gemini 3.1 Flash Live

Preview

Live API model for real-time audio-to-audio dialogue; Google calls it "our high-quality, low-latency audio-to-audio (A2A) model". Rates differ per input type: input $0.75 (text) / $3.00 or $0.005 per minute (audio) / $1.00 or $0.002 per minute (image/video); output $4.50 (text) / $12.00 or $0.018 per minute (audio). Values shown are the TEXT tier, matching how the catalog carries the other multi-tier Gemini rows. Grounding with Google Search: 5,000 free requests per month shared across Gemini 3.x, then $14 per 1,000 requests. Google states "No shutdown date announced". Google's current models page publishes no input/output token limits for this endpoint (read 2026-08-19), so context_window and max_output_tokens are null rather than carried over from a page that no longer states them. Lifecycle read first-party from Google's deprecations table on 2026-08-19.

Gemini 3.1 Flash Live by Google costs $0.75 per 1M input tokens and $4.50 per 1M output tokens ($1.69/1M blended). It is in preview.
