o3 Mini High

OpenAI's reasoning model with extended chain-of-thought processing and multimodal input support, sitting between o3 Mini and the o1-pro tier in the reasoning model lineup.

Strengths

Performs extended reasoning and chain-of-thought processing on complex problems with support for both text and image inputs.

Best for

Complex reasoning tasks that benefit from deliberate chain-of-thought processing while maintaining cost efficiency relative to o1-pro.

Limitations

The 200k token context window is smaller than GPT-4.1 models, and reasoning models trade throughput for reasoning depth, making them less suitable for high-volume classification or extraction tasks.
