Gemini 3.1 Pro

Google’s flagship. 1M context, native multimodal.

Temporarily unavailable

Our upstream lists gemini-3.1-pro-preview but is not currently serving it, so calls fail rather than bill. Upstream capacity moves around week to week and this one may well come back — we would rather show you the gap than take a signup for it today. For work you can run today, Gemini 3.5 Flash is live at $0.75/M input.
