Gemini 3.1 Pro
Google's most capable AI model — with major advances in reasoning, coding, and agentic intelligence
2× the reasoning of Gemini 3 Pro • #1 on 12 of 18 benchmarks • Native SVG & 3D code rendering
What's New in Gemini 3.1 Pro
Every dimension reimagined — reasoning, coding, multimodal understanding, and speed
2× Abstract Reasoning
Scores 77.1% on ARC-AGI-2 — more than double Gemini 3 Pro. Solves novel visual-logic puzzles requiring multi-step abstraction that previous models could not.
1M Token Context, 65K Output
Process entire codebases, 8.4 hours of audio, 900-page PDFs, or 1 hour of video in a single prompt. Output expanded to 65,536 tokens — no more truncation.
Elite Software Engineering
80.6% SWE-Bench Verified pass rate. LiveCodeBench Pro Elo of 2887 — outperforming GPT-5.2. Handles real-world software issues autonomously.
Native SVG & 3D Code Rendering
Generates, animates, and visually renders SVG graphics and 3D code directly from natural language descriptions — a capability not commonly found in other models.
Long-Horizon Agentic Workflows
Scores 33.5% on APEX-Agents, 69.2% on MCP Atlas for tool coordination, and 85.9% on BrowseComp for autonomous web research. Strong performance across agentic benchmarks.
Three-Tier Thinking System
Choose between Low, Medium, or High compute modes. Balance output speed vs. reasoning depth for every task — from quick answers to complex problem solving.
