Overview

  • OpenAI announced on X that Plus, Pro, and Business users can now adjust GPT-5's Thinking setting on the ChatGPT web client.
  • Modes include a new Standard default that balances speed and quality, an Extended option for deeper reasoning, and Pro-only Lightweight and Heavy choices.
  • The selected Thinking mode persists across new web conversations until users change it, making preferences stick by default.
  • ChatGPT lead Nick Turley said taking GPT-4o offline too quickly was a mistake and emphasized user attachment to model personalities and the need for expectation management.
  • OpenAI reopened GPT-4o access for Plus members and is developing personalization features such as selectable personalities, with IT之家 previously reporting a child-focused ChatGPT in development.
