Update on thinking time settings for GPT-5.2 Thinking in ChatGPT

Series of updates to thinking time settings for GPT-5.2 Thinking:

• January 10, 2026: Lowered Standard and Light thinking time as users prefer faster responses. Extended thinking setting was unintentionally changed to be lower, which was then fixed.
• February 3, 2026: Made another small reduction to Standard thinking time based on testing.
• February 4, 2026: Restored Extended thinking level for GPT-5.2 Thinking to its prior setting, correcting the inadvertent reduction from January.

Thinking time is not directly comparable across different models. Each model is tuned independently to what works best for users.
