AI rate limits: meaning and free-plan examples

Answer in brief

AI rate limits restrict how much you can request within a time window. They can count messages, tokens or a particular action such as image creation. ChatGPT's free tools have separate limits, so hitting an upload cap doesn't necessarily mean every feature is unavailable.

AI rate limits: what changes your decision

A daily allowance is only one kind of restriction. Developer APIs can also limit requests per minute or tokens per minute. A request can fail because you're sending too quickly even when there's money or credits left in the account.

Look for both a usage allowance and a rate limit. If an API returns a rate-limit error, slow retries rather than sending the same request repeatedly.
