Gemini 3.1 Pro

Gemini 3.1 Pro leads reasoning benchmarks as of mid-2026 and represents Google’s most capable general model. Its multimodal architecture natively handles video and audio alongside text, with a context window approaching 1M tokens. Pricing is $2/$12 per million tokens up to 200K context, doubling for longer contexts. It is the go-to choice for teams that need both frontier reasoning and rich media understanding in one model.
