OpenAI recently updated their limit documentation so there are tiers now. You automatically scale up through the tiers but you may be able to jump the line a bit by paying some extra. But I think you will have to wait 7-14 days since first payment before going to next tier. Try finding the usage and limits docs in your account.
Edit: Oh I see I'm in Tier 3 and the RPD limit on vision preview is still 100/day. Guess that's just it for now. It is labelled preview after all.
Thanks.
Yeah, it seems that even on Tier 5 the limit is 100/day, that's not enough for any production app.
I hope they go out of preview mode soon and therefore increase the limits
