OpenAI: o4 Mini High

OpenAI's o4-mini-high, released on April 16, 2025, is a compact reasoning model optimized for speed and cost-efficiency, building upon the o4-mini with enhanced reasoning effort. It exhibits moderate speed performance, ranking in the 35th percentile, and is positioned at premium pricing levels, falling into the 14th percentile. A standout feature is its exceptional reliability, achieving a perfect 100% success rate across all benchmarks. The model demonstrates strong capabilities across several domains. It achieved perfect accuracy in General Knowledge, notably being the most accurate model at its price point and speed. Its Reasoning and Coding performance are also highly competitive, scoring 98.0% and 93.0% respectively, placing it in the 89th and 79th percentiles. Instruction Following and Email Classification also show solid results at 71.0% and 99.0%. A key weakness is observed in the Hallucinations benchmark, where it scored 62.0%, indicating a tendency to not always acknowledge uncertainty. Despite this, its high accuracy in STEM tasks, visual problem-solving, and code editing, coupled with its ability to chain tools and solve multi-step tasks quickly, positions it as a powerful tool for high-throughput scenarios.
