Opt-out = 500 Premium Request, The old pro plan.
New Pro Plan = Unlimited Request but with Rate limits.
As a customer, Many people saying can’t use new pro plan because after 5 request getting insanely rate limit time. If you gonna buy Pro plan, think about it.
I’m concerned that going back to the Opt-out plan would be a downgrade compared to the previous version (before the change to the current ‘PRO’ plan), for me—and many others—the current ‘PRO’ plan feels underwhelming, making us wonder, ‘Why this change?’, I know there are heavy and casual users, but I’d bet many users barely hit 500 requests a month (casual users)
The additional difference between old and new plan is that the old plan doesn’t depend on tokens usage - an empty context request counts equally to a request that fills almost all available context window.
ALSO on old plan there are some (naturally weaker) free models that you can use without worrying that you’ll suddenly hit rate limits and have to wait for hours. Suitable for quite a lot of tasks.
