Pro mode for the toughest questions
Pro mode is now available for GPT-5.6 variants and GPT-6 Astra. It is intended for the hardest questions that call for especially thorough reasoning. Use it, for example, to analyse a complex case or compare several interdependent arguments.
After choosing your model, select Pro as the reasoning mode. Reasoning effort is a separate setting. In the Czech interface, these fields are labelled Režim uvažování and Úsilí při uvažování. The screenshot shows Pro mode with the effort set to Maximální (maximum).
