OpenAI: o1-pro

OpenAI's o1-pro model, released on March 19, 2025, is designed for complex reasoning through reinforcement learning. This model exhibits significantly longer response times, ranking in the 4th percentile for speed across benchmarks, indicating it performs among the slowest models. Its pricing is positioned at premium levels, ranking in the 0th percentile, making it one of the most expensive options available. However, the o1-pro demonstrates strong reliability, achieving an 88% success rate across benchmarks, suggesting consistent delivery of usable responses with few technical issues. In terms of performance across categories, the o1-pro shows a notable strength in Instruction Following, achieving 84.0% accuracy (91st percentile), indicating a high capability for precision in complex directives. Its Email Classification accuracy is also respectable at 98.0% (49th percentile). However, the model struggles with Ethics (68.0% accuracy, 16th percentile) and Coding (75.0% accuracy, 31st percentile), suggesting these areas are notable weaknesses. The high cost and duration across all benchmarks, particularly for Ethics and Coding, further underscore its premium pricing and slower processing.
