Google Releases Gemini 3.1 Pro with Major Reasoning Gains
Narrative
Google releases Gemini 3.1 Pro, rolling it out across the Gemini app, NotebookLM, Gemini API/AI Studio, and Vertex AI. Google highlights a core reasoning jump (77.1% verified on ARC-AGI-2) and strong coding performance (80.6% on SWE-Bench Verified).
Reality
Released Feb 19, 2026. ARC-AGI-2 (77.1% verified) and SWE-Bench Verified (80.6%) are Google-reported figures. Availability across Gemini app, NotebookLM, Gemini API/AI Studio, and Vertex AI is confirmed by Google. Third-party assessments exist, but methodology and comparability vary.
Implication
Google is pushing “practical reasoning + distribution” as the wedge. If rollout stability holds, Gemini 3.1 Pro becomes an easy enterprise default: integrated, measurable, and broadly available. Benchmark debates will only get louder as the gap narrows.
