I ran into this rate limit recently when generating a logo in SVG. It's 45 messages per 5 hours (with some caveats). It's documented here [0].

> Your limit gets used up faster with longer conversations, notably with large attachments. For example, if you upload a copy of The Great Gatsby, you may only be able to send 15 messages in that conversation within 5 hours, as each time you send a message, Claude “re-reads” the entire conversation, including any large attachments.

Seems to also be limited by tokens. It’s still quite obscure.

Even moreso:

> Please note that these limits may vary depending on Claude’s current capacity.

Fine for the free tier of course, but not great for the paid version.

With a fixed capacity, someone’s traffic is going to be rejected. I think it makes sense to have a variable rate limit depending on available capacity and demand.

For what it's worth, I haven't run into any limitations while using the API side. Although I also haven't really had to use it so extensively that it would be a problem.

ChatGPT says the same about capacity for Pro I think.
