OpenAI: o4 Mini

OpenAI o4-mini, created on April 16, 2025, is a compact reasoning model designed for fast, cost-efficient performance with strong multimodal and agentic capabilities. It demonstrates competitive response times, ranking in the 41st percentile for speed, and offers moderate pricing, placing it in the 21st percentile. Notably, o4-mini exhibits exceptional reliability, achieving a perfect 100th percentile, indicating minimal technical failures. The model excels across various benchmarks. It achieved outstanding accuracy in Coding (94.0%, 95th percentile), Instruction Following (76.0%, 91st percentile), and Reasoning (99.0%, 97th percentile). Its General Knowledge performance was perfect at 100.0% accuracy, making it the most accurate model at its price point and among models of similar speed. While its Email Classification (98.0%, 59th percentile) and Ethics (99.0%, 54th percentile) scores are strong, they are not as exceptionally high in percentile ranking as its other categories. Overall, o4-mini's key strengths lie in its high accuracy across STEM tasks, visual problem-solving, and code editing, making it well-suited for high-throughput scenarios where latency and cost are critical.
