OpenAI: o3 Mini

OpenAI o3 Mini is a text-and-file model with a 200,000-token context window and up to 100,000 completion tokens per response. It supports tool use and built-in reasoning, making it suited for multi-step tasks that benefit from structured problem-solving. Structured output support is unconfirmed from available data. At $1.10 per million input tokens and $4.40 per million output tokens, it sits in the mid-range tier, cheaper than flagship models but not a budget option. Its blended benchmark score of 46.6 covers only two benchmarks, so that figure is preliminary rather than a reliable cross-domain picture. Teams that need long-context reasoning with tool integration and can tolerate limited third-party benchmark coverage should shortlist it; those needing well-validated performance across diverse tasks may want to wait for broader evaluation data before committing.
