OpenAI’s recommended flagship for complex reasoning and coding.

Reasoning & coding
Documented reasoning controls (low, medium, high, xhigh, max) let you tune effort. Check results and cost on your own tasks.
The tradeoff
A larger context budget does not establish better recall or answer quality. Long prompts increase the rate for the whole request. Audio/video workflows need conversion unless documented separately by the provider.
Task guidance follows the documented capabilities. It is not an independent benchmark result.
