I wanted to increase my rate limit and received an email from support that they don’t increase rate limit for Codex. So it’s not possible to create an application with many users based on Codex because when your application has more users, you will get stuck on rate limit.
Creating an application on top of Codex that is used by many users is impossible (due to rate limit)
But to be fair, other models are also great, so we can use other models.
But Codex seems to be the best for my use case, so it still would be nice, if it could be used with higher rate limits.
