As we recently announced, our Plus plan comes with early access to new, experimental features. We are beginning to roll out a way for Plus users the ability to choose between different versions of ChatGPT:
Default: the standard ChatGPT modelTurbo: optimized for speed (alpha)
Version selection is made easy with a dedicated dropdown menu at the top of the page. Depending on feedback, we may roll out this feature (or just Turbo) to all users soon.
