OpenAI: o3 Mini High

OpenAI o3 Mini High is a text-and-file model with a 200,000-token context window and up to 100,000 tokens of completion output. It supports tool use and reasoning, making it applicable to multi-step tasks that require external calls or deliberate chain-of-thought processing. Structured output support is unconfirmed based on available data. At $1.1 per million input tokens and $4.4 per million output tokens, it sits in a mid-range price bracket. Its blended benchmark score of 54.0 covers only three benchmarks, so broad performance comparisons should be treated with caution. The coding-specific score of 69.4 gives it a clearer signal for development use cases, and teams prioritizing coding assistance alongside large-context document processing will find the most grounded reason to shortlist it here.
