Google: Gemini 3.1 Pro Preview

Google's Gemini 3.1 Pro Preview, a frontier reasoning model created on February 19, 2026, demonstrates a strong performance profile, particularly in reliability and specific accuracy benchmarks. While its speed performance is moderate, ranking in the 21st percentile, its pricing tends to be premium, positioned in the 5th percentile. A standout feature is its exceptional reliability, achieving a perfect 100% success rate across all 8 benchmarks, indicating minimal technical failures and consistent response delivery. The model excels in critical areas such as Hallucinations, Reasoning, and Ethics, achieving 100% accuracy in these categories, often at competitive costs and speeds within their respective benchmarks. It also shows high accuracy in Instruction Following (93.9%), Coding (96.0%), and Mathematics (95.9%), indicating robust capabilities in complex problem-solving and technical tasks. Its General Knowledge is solid at 99.5%. A relative weakness appears in Email Classification, where its 98.0% accuracy, while good, places it in the 53rd percentile, suggesting room for improvement compared to other models in this specific task. Designed for advanced development and agentic systems, Gemini 3.1 Pro Preview's strengths lie in its high-precision reasoning across multimodal inputs, enhanced software engineering performance, and efficient token usage for complex workflows, making it well-suited for autonomous agents and high-context enterprise tasks.
