OpenAI: o3 Mini
Analysis Summary
OpenAI o3 Mini is a compact reasoning model from OpenAI, released January 2025, with tool use, function calling, and a 200K context window. Its GPQA of 0.748 and LiveCodeBench of 0.717 are strong for its tier, and its intelligence index of 25.9 places it well above most lightweight models in the field.
For businesses, o3 Mini is well-suited to coding assistance, structured reasoning, and tool-augmented workflows where a full frontier model is not required. Its 200K context window supports long-document analysis, and function calling enables integration into agentic pipelines, though its agentic index of 17.7 is modest compared to top-tier agents.
At $1.10 input and $4.40 output per million tokens, it sits at a reasonable mid-market price for OpenAI's ecosystem. Development teams and technical users who want reliable OpenAI infrastructure with strong coding and reasoning at lower cost than GPT-5-class models will find o3 Mini a practical fit.
