Gemini 3.1 Pro Launched: Smarter AI for Complex Tasks

2/19/2026

The frontier of artificial intelligence continues to expand. Following last week's major update to Gemini 3 Deep Think, Google has now released the upgraded core intelligence powering those breakthroughs: Gemini 3.1 Pro. Designed specifically for scenarios where simple answers are insufficient, this model brings advanced, real-world reasoning to the hardest engineering and scientific challenges. https://storage.googleapis.com/gweb-uniblog-publish-prod/original_images/gemini_3-1-pro__benchmarks.gif The performance metrics are a testament to this leap. On the ARC-AGI-2 benchmark, which evaluates a model's ability to solve entirely new abstract logic patterns, Gemini 3.1 Pro achieved a verified score of 77.1%. This not only more than doubles the reasoning performance of Gemini 3 Pro (31.1%), but also comfortably outpaces rivals like Claude Opus 4.6 (68.8%) and GPT-5.2 (52.9%). https://storage.googleapis.com/gweb-uniblog-publish-prod/original_videos/SVGs_keyword_v3.mp4#t=0.001 The provided benchmark charts reveal a model built for high-level technical tasks. Gemini 3.1 Pro dominates competitive coding with a LiveCodeBench Pro score of 2887 Elo and shines in scientific knowledge with a 94.3% on GPQA Diamond. It also showcases robust agentic search capabilities, hitting 85.9% on BrowseComp, beating out Opus 4.6. https://storage.googleapis.com/gweb-uniblog-publish-prod/original_videos/Gemini_3.1_Demo_GC_V6-lr.mp4#t=0.001 Starting today, the model is rolling out in preview across Google's entire ecosystem. Developers can access it via the Gemini API in Google AI Studio, Gemini CLI, Android Studio, and the agentic platform Google Antigravity. Enterprise clients can utilize it through Vertex AI and Gemini Enterprise, while consumers on the Google AI Pro and Ultra plans can experience the upgraded intelligence natively in the Gemini app and exclusively on NotebookLM. https://storage.googleapis.com/gweb-uniblog-publish-prod/original_videos/Mumuration_SIM_v2_SMALL.mp4#t=0.001 https://storage.googleapis.com/gweb-uniblog-publish-prod/original_videos/catherineearnshaw_web_design_v1_SMALL.mp4#t=0.001
