What I didn't realize though, is that the limit doesn't reset each 5 hours as is the case for claude. I hit the limit of the free tier about 2 hours in, and while I was expecting to be able to continue later today, it alerts me that I can continue in a week.
So my hype for the amount of tokens one gets compared to claude was a bit too eager. Hitting the limit and having to wait a week probably means that we get a comparable token amount vs the $20 claude plan. I wonder how much more I'd get when buying the $20 plus package. The pricing page doesn't make that clear (since there was no free plan before yesterday I guess): https://developers.openai.com/codex/pricing/
