OpenAI: o3 Mini · fastrouter

OpenAI o3-mini (January 2025 version) is a specialized reasoning model optimized for STEM domains while maintaining cost efficiency. This model features adjustable reasoning capabilities and demonstrates exceptional performance in science, mathematics, and coding tasks, with expert evaluators preferring its responses 56% of the time over previous versions and noting a 39% reduction in major errors on complex questions. Even at medium reasoning settings, o3-mini matches the larger o1 model's performance on challenging evaluations like AIME and GPQA while maintaining significantly lower latency and cost profiles. The model supports developer-focused features including function calling, structured outputs, and streaming capabilities, though it lacks vision processing functionality. This text-only design focuses computational resources on reasoning quality, making it particularly valuable for technical applications requiring accurate problem-solving without multimodal requirements.
