Google released Gemini 3.1 Pro on February 19, 2026, reporting more than double the reasoning performance of its predecessor on key benchmarks. The model scored 77.1% on ARC-AGI-2, a test designed to measure general intelligence capabilities.

What Happened

Gemini 3.1 Pro builds on the Deep Think reasoning architecture introduced with Gemini 3, applying it to a broader range of tasks. The model shows significant improvements in coding, multimodal understanding, scientific reasoning, and mathematical problem-solving compared to Gemini 3 Pro.

Google launched the model in preview across the Gemini API, Vertex AI, the Gemini consumer app, and NotebookLM. The preview period lets Google validate performance and gather feedback before general availability, particularly for complex agentic workflows that require sustained reasoning across multiple steps.

The ARC-AGI-2 benchmark is notable because it measures a model's ability to solve novel problems it has never seen before, rather than pattern-matching against training data. Scoring 77.1% on this benchmark represents a meaningful step forward in generalized reasoning.

Why It Matters for Creators

Stronger reasoning directly impacts the quality of AI-assisted creative work. If you use Gemini for writing, code generation, or data analysis, the 3.1 Pro upgrade means fewer logical errors and better handling of multi-step tasks. The improvement is most noticeable in tasks that require the model to think through a problem rather than recall information.

For developers building AI-powered creative tools on Google's API, the reasoning upgrade means more reliable agent behavior. Complex workflows like automated content pipelines, multi-step editing processes, and research-to-draft systems will produce more consistent results. Google Flow already uses Gemini to power its unified creative workspace, and the 3.1 Pro upgrade directly improves how Flow interprets creative prompts.

What to Do Next

Access Gemini 3.1 Pro through the Gemini app, Google AI Studio, or the Vertex AI API. If you use NotebookLM for research, the model is already available there. Compare its output quality against your current model choice on a complex reasoning task to see the difference firsthand. Apple's upcoming Gemini-powered Siri will bring these reasoning improvements to iOS, making Gemini 3.1 Pro capabilities accessible through voice commands on iPhone.
