Summary

Google has launched Gemini 3.1 Pro, a new model designed for complex tasks, demonstrating significant advancements in core reasoning. It achieved a 77.1% score on Arc AGI 2, more than doubling Gemini 3 Pro's performance, and shows state-of-the-art results across various benchmarks, though slightly behind Opus 4.6 in some areas. The model features a 1 million token context window, priced at $2 per 1 million input tokens and $12 per 1 million output tokens. Available via Gemini Studio, the Gemini app, CGA, and APIs, it excels in generating complex code for applications like Minecraft clones, browser-based macOS mimics, double wishbone suspension systems, and realistic city planner apps. It also demonstrates strong front-end capabilities, SVG generation, iOS app element replication, and interactive simulations like a solar system model.

Key takeaway

For engineering and product teams evaluating advanced AI models for complex, multi-step problem-solving, Gemini 3.1 Pro offers a compelling option due to its enhanced reasoning and strong performance in code generation and interactive simulations. Your team should explore its capabilities for front-end development, system design, and creating dynamic visualizations, especially given its competitive pricing and 1 million token context window, while being mindful of occasional hallucinations.
