Google Launches Gemini 3.1 Pro with 77.1% on ARC-AGI-2

Google Announces Gemini 3.1 Pro with Doubled Reasoning Performance and New Creative Capabilities

Google has officially announced the launch of Gemini 3.1 Pro, a significant update to its AI model that represents “a step forward in core reasoning.” The new model achieved a verified score of 77.1% on the ARC-AGI-2 benchmark, which evaluates a model’s ability to solve entirely new logic patterns - more than double the reasoning performance of Gemini 3 Pro.

Immediate Availability

Gemini 3.1 Pro is beginning to roll out today, February 19, 2026, across multiple platforms:

  • For developers: Preview via Gemini API in Google AI Studio, Gemini CLI, Google’s agentic development platform Antigravity, and Android Studio
  • For enterprises: Vertex AI and Gemini Enterprise
  • For consumers: Gemini app and NotebookLM (exclusively for Pro and Ultra users)

Enhanced Reasoning

Building on the Gemini 3 series, 3.1 Pro represents a significant improvement in core reasoning. The model is designed for tasks where a simple answer isn’t enough, bringing advanced reasoning and making it useful for your hardest challenges.

On ARC-AGI-2, a benchmark that evaluates a model’s ability to solve entirely new logic patterns, 3.1 Pro achieved 77.1% - more than double the reasoning performance of 3 Pro.

Demonstrated Capabilities

Google highlighted several practical applications of the model’s enhanced capabilities:

Code-based animation: 3.1 Pro can generate website-ready, animated SVGs directly from a text prompt. Because these are built in pure code rather than pixels, they remain crisp at any scale and maintain incredibly small file sizes compared to traditional video.

Complex system synthesis: Utilizing advanced reasoning, 3.1 Pro can bridge the gap between complex APIs and user-friendly design. In one example, the model built a live aerospace dashboard, successfully configuring a public telemetry stream to visualize the International Space Station’s orbit.

Interactive design: 3.1 Pro codes a complex 3D starling murmuration. It doesn’t just generate visual code; it builds an immersive experience where users can manipulate the flock with hand-tracking and listen to a generative score that shifts based on birds’ movement. For researchers and designers, this provides a powerful way to prototype sensory-rich interfaces.

Creative coding: 3.1 Pro can translate literary themes into functional code. When prompted to build a modern personal portfolio for Emily Brontë’s “Wuthering Heights,” the model didn’t just summarize the text. It reasoned through the novel’s atmospheric tone to design a sleek, contemporary interface, creating a website that captures the essence of the protagonist.

Preview and Next Steps

Google is releasing 3.1 Pro in preview today to validate these updates and continue to make further advancements in areas such as ambitious agentic workflows before making it generally available soon.

Since releasing Gemini 3 Pro in November, user feedback and the pace of progress have driven these rapid improvements.
