Gemini 3.1 Pro Preview: long context and multimodal input
Gemini 3.1 Pro targets long-document and multimodal API workloads. Check the current endpoint's release state, limits and account access before production use.
What changed
- Google positioned 3.1 Pro as the Pro tier with a 1.05M-token context window and multimodal input.
- Pricing steps up above 200K tokens, which matters for long-document workloads.
- Preview or production availability is endpoint- and account-specific; use Google's current model page for the intended API surface.
Best fit
- Very long documents
- Multimodal input
- Google Workspace integration
What to be careful about
- Do not infer agentic-coding quality from an unmatched or incomplete benchmark row; test the current API and configuration on your own tasks.
- Prompts above 200K tokens move to a higher rate card.
