I'm using the Codex Business subscription (about 30€) already for multiple months. Even there they cut back on the quota. A few months back it was hard for me to reach the limit. Now it is easier.
Still, in comparison with Claude Code, the quota of Codex is a much better deal. However, they should not make it worse...
OpenAI had a promotion that gave everyone double their rate limits until April 2nd.
I have the exact opposite experience. I can run claude forever, my codex quota was done by Wednesday morning.
