OpenAI: o3 Mini High

OpenAI o3-mini-high, released on February 12, 2025, is a specialized language model designed for STEM reasoning, building upon the o3-mini with enhanced reasoning effort. It exhibits moderate speed performance, ranking in the 24th percentile across benchmarks, and is positioned at premium pricing levels, falling into the 12th percentile for cost. A standout feature is its exceptional reliability, achieving the 100th percentile with minimal technical failures, ensuring consistent response delivery. The model demonstrates strong performance across various benchmarks. It excels in Reasoning (98.0% accuracy, 94th percentile) and Coding (90.0% accuracy, 80th percentile), aligning with its STEM optimization. Its General Knowledge is perfect at 100.0% accuracy, notably being the most accurate model at its price point and among models of similar speed. While Instruction Following shows solid accuracy (62.0%, 72nd percentile), Email Classification (97.0%, 47th percentile) and Ethics (98.0%, 40th percentile) are competent but not top-tier compared to other models in their respective categories. Key strengths include its robust reasoning capabilities, high accuracy in coding and general knowledge, and unparalleled reliability. Its primary weakness lies in its premium pricing, which may be a consideration for cost-sensitive applications despite its performance.
