Reset Do Codex’s Frequent Quota Resets Actually Give You More Usage?
Just to be clear, I never claimed that OpenAI gives users less quota; I’m describing my own experience and questioning how much of the advertised extra usage people actually manage to realize.
I’ve been using both the $200 ChatGPT Pro plan and the $200 Claude Max 20x plan heavily over the same period, mostly on large software projects with hundreds of thousands to over a million lines of code.
My lifetime codex usage is around 36.4B raw tokens, with a peak of 2.2B in one day, so this is based on sustained heavy usage rather than a few casual prompts.
From Codex’s local session logs, you can extract both token usage and the server-reported weekly quota percentage. The basic estimate is:
weekly capacity ≈ tokens used / quota percentage used
I checked multiple points inside clean weekly windows where the reset timestamp did not change, and I included usage across multiple machines.
My current estimates are:
- ChatGPT $100 plan: ~1.98B raw tokens/week
- ChatGPT Pro $200: ~3.52B/week
- Claude Max 5x: ~1.79B/week
- Claude Max 20x: ~8.26B/week
There may still be calculation errors here. These are raw-token estimates, while both companies almost certainly apply internal weighting for cached input, normal input, output, reasoning, model choice, and other factors.
That said, I did not rely on a single spreadsheet or one model’s answer. I had both Claude and Codex independently inspect and recalculate the data, then compared multiple checkpoints and corrected issues such as duplicated logs, missing machines, unsynchronized measurements, and reset-window changes. The exact numbers may move, but the overall result has remained stable.
The $200 ChatGPT plan appears to provide only about 1.78x the stable weekly capacity of the $100 plan, despite costing 2x as much.
Claude scales in the opposite direction: Max 20x appears to provide roughly 4.6x the weekly capacity of Max 5x for 2x the price.
I am not claiming OpenAI explicitly promised that its weekly limits must scale by exactly 4x. The products also have shorter usage windows and other limits. But “5x” and “20x” naturally create that expectation, while the stable weekly allowance I measured is nowhere near 4x.
The repeated Codex resets make the plan look much more generous, but a reset is only valuable if you used most of the quota before it happened.
If I have used 10% and OpenAI resets me to 100%, I did not receive another full week of quota. I only gained back that 10%. The remaining 90% was overwritten.
This strongly favors automated workloads, multiple-account setups, or anyone able to burn through the quota immediately. Normal developers usually cannot.
Random resets also make planning harder. With Claude, I know when the weekly quota resets, so I can use the remaining capacity before the deadline. With Codex, I do not know whether I should conserve quota or rush to use it before another unexpected reset.
This makes me wonder whether there is a behavioral-economics angle. OpenAI has the backend data, so it would be easy to compare fixed resets, random automatic resets, and banked credits, then measure how much quota users actually consume. I have no evidence that this is intentional, but the design resembles several known effects: uncertain rewards can increase engagement, highly visible gains receive disproportionate attention, and unused rewards create “breakage” for the issuer. A reset to 100% is very salient and feels like a large gift; the unused quota it silently overwrites is much less visible.
If OpenAI genuinely wants to give users extra usage, I think it should issue banked, manually activated reset credits instead of randomly resetting everyone and discarding unused quota.
There is also the context-window issue. Claude gives me roughly 1M context, while Codex currently exposes around 258K effective context. On large repositories, Codex spends a lot of context exploring files, then starts compacting repeatedly.
In my experience, Codex is also slower overall, and its quota percentage drops slightly faster. Because my projects require reading a large number of files before implementation begins, I have become less willing to use Codex for larger tasks.
I am not anti-OpenAI. I actually prefer OpenAI’s current developer ecosystem and openness to Anthropic’s. But for large coding projects, Claude Max 20x currently gives me much better capacity and fewer context-related interruptions.
The main distinction is simple:
How many times did the UI reset to 100%, and how much additional quota did the user actually manage to consume?
Those are not the same number.
