By OpenAI
Model family: GPT
Thinking is designed to plan steps, reconcile evidence, and return well-structured outputs for complex work. You can control depth in ChatGPT with Standard, Extended, Light, or Heavy thinking modes, and in the API by lowering reasoning effort when latency matters. The GPT-5 system routes to the thinking tier when prompts are complex or when you explicitly ask for deeper analysis.

Overview
The Thinking variant is the deeper-reasoning option. It adjusts how much thinking it does based on task difficulty, trading speed for accuracy when needed, and supports a user-visible thinking-time toggle in ChatGPT.
