About the model
o3 is OpenAI's top model in the "o" series for deep step-by-step reasoning: math, logic, analysis and development, wherever a well-founded conclusion is needed. The model understands images, reliably calls tools (function-calling) and suits agents that need a detailed breakdown of the task. It holds a large context and does well where ordinary chat models get lost in the details. o3 works confidently with Russian.
