o4-mini is a compact, fast OpenAI model from the "o" series: deep reasoning at a noticeably lower cost. It lays out step-by-step reasoning for complex tasks but answers faster than the larger models in the series, which is handy at high volume. The model is strong in math, logic and code, understands images and reliably calls tools (function-calling). It holds context well and works as an affordable foundation for agents and analytics. Its Russian is average.
