## Definition

Gemini 3.1 Pro is Google DeepMind's flagship reasoning model, released [February 19, 2026](https://blog.google/innovation-and-ai/models-and-research/gemini-models/gemini-3-1-pro/). It introduces a "thinking" inference mode with three configurable effort levels, a 1-million-token context window, and native multimodal input across text, image, video, audio, and PDF.

The model debuted with a 77.1% score on ARC-AGI-2 — more than double Gemini 3 Pro's result — and a record 94.3% on GPQA Diamond graduate-level science. Priced at $2 input / $12 output per million tokens (standard context), it undercuts comparable frontier models by roughly half while leading 13 of 16 major benchmarks on launch.

## Analogy

Think of it as Gemini's turbo mode: same engine, but with a configurable amount of 'thinking time' before every answer.

## Why it's emerging now

Gemini 3.1 Pro launched February 19 with record ARC-AGI-2 and GPQA scores, immediately available in GitHub Copilot and Vertex AI. Google Cloud Next on April 22 promoted it as the backbone of Deep Research agents — putting it at the center of the enterprise agentic AI wave at under half the cost of comparable frontier models.
