We're making a small update to the model picker in ChatGPT! We know it's critical to a lot of people's work, and that we have a lot of paying users who care deeply about this one, so wanted to take some time to detail out the tweak. One important point upfront – you'll still have access to the same models and reasoning levels, besides the removal of thinking-light (used by less than 1% of our paid users). You'll see an updated list of options (similar to how Codex works): - Instant - Medium (Thinking-Standard) - High (Thinking-Extended) - Extra High (Thinking-Heavy) [for pro users] - Pro (with option to choose Pro-Standard or Pro-Extended) [for pro users] The intent is to make it easier to choose the balance of speed and effort that works best for your task. We also took into account community feedback to make sure: a) Thinking-heavy is easily accessible b) Pro standard and Pro extended are easily accessible c) We clearly communicate these changes Given that, here are some release notes detailing the updates - Give it a try, it's rolling out today, and we're always open to feedback, we know it's important to get it right!
