Operator guidance
Route here for the hardest reasoning/agentic-coding tasks once GA. While still in preview (no free tier, higher cost than 2.5 Pro), most production traffic should stay on Gemini 2.5 Pro until 3.1 Pro reaches general availability.
Use cases
- Frontier reasoning and complex problem-solving where 2.5 Pro's ceiling isn't enough
- Agentic coding and multi-step tool-use workflows (including a dedicated custom-tools endpoint)
Limitations
- Still in preview status as of 2026-07 — not yet generally available, per Google's own launch post
- No free tier on the API pricing page
- Tiered pricing: prompts above 200K tokens cost roughly double
- Capability ratings are qualitative, not a single cited benchmark run
