As we recently announced, our Plus plan comes with early access to new, experimental features. We are beginning to roll out the ability for Plus users 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.
