o4 Mini High

o4-mini with reasoning_effort set to high, a compact reasoning model that performs extended chain-of-thought processing with multimodal input support.

Strengths

Applies reasoning at an elevated computational level within the o-series compact tier, handling multimodal inputs and complex reasoning tasks without the resource cost of larger models.

Best for

Workloads requiring extended reasoning on images and text where you need stronger inference than o4-mini but want to stay within the compact reasoning family.

Limitations

Still smaller and less capable than frontier models like o3; intended for reasoning tasks where the standard o4-mini reasoning_effort setting leaves problems unsolved.
