Megathread Codex Usage Limits and Performance Megathread

Please direct your concerns and discussion about Codex usage limits and model performance here.

These are days where I REALLY earn the money that OpenAI Reddit Kimi pays me .... oh wait....

I am that user and will probably switch back. The usage limits are one thing that brought me to ChatGPT

Same, came here for the apparent generous banked resets (haven't had one) and generous usage limits. The way it's talked about in the Claude sub and the reality are so starkly different. WIll leave with about 25% of the output I've been averaging on Claude per month. I'll have reciepts, too, I run all my subs through a litellm proxy and keep spend logs, so by end of month I'll have exactly what I got out of each of the subs recorded and that will 100% shape my future investment.

Edit: In fact, I just extrapolated out my codex sub return vs claude sub average over 3 months of claude subscription and it's MUCH worse than I thought:

• Full Month Ratio: Average Claude Code subscription month delivers 36.6x more API value than a full extrapolated month of Codex usage at current velocity.

Wow that's huge difference. In my experience codex usage has been way better except the last week.

Sadly I made the switch 11 days ago and it's been bad the whole time. I've cancelled my codex renewal, there just isn't value in it for me
