OpenAI Brought the 5-Hour Limit Back for ChatGPT Plus. Pro Keeps Its Pass.
Quick verdict
OpenAI turned the rolling 5-hour usage cap back on for ChatGPT Plus. It applies to Codex and ChatGPT Work, it started August 25, and it hits every $20-a-month Plus account. The $100 and $200 Pro plans stay exempt for the next few months. If you code against a Plus plan, you now bump into two ceilings again instead of one: the weekly quota and the 5-hour window.
Thibault Sottiaux, who leads Codex and ChatGPT Work at OpenAI, announced it directly. The reasoning is compute, and the effect is a sharper line between the cheap tier and the expensive one.
What actually changed
- The 5-hour rolling limit is back on Plus accounts for both Codex and ChatGPT Work, effective August 25.
- Plus users now sit under a short-window cap plus their weekly allowance, not the weekly allowance alone.
- The $100 and $200 Pro plans keep the 5-hour gate switched off "for the upcoming months," which sounds temporary.
- Enterprise and Edu plans run on a separate credit system and were never inside this change.
- OpenAI had lifted the same 5-hour cap on July 12, so this is a reversal of a six-week-old loosening.
Sottiaux framed the cap as load management. The short window stops a burst of activity from draining a full week of quota in one sitting, which lets OpenAI keep the weekly number generous. His words: casual and newer Plus users sometimes "accidentally eat through their whole week's usage," and the 5-hour limit smooths that out.
Why it matters
The plain reading on the Plus side is that heavy usage on the cheapest paid tier is the thing OpenAI most wants to shape. A weekly quota alone lets a motivated user front-load everything into a Monday coding spree. A 5-hour rolling window forces that same work to spread out. For a casual user that's invisible. For anyone running Codex as a daily driver on Plus, it's a real interruption.
The tier split is the part worth sitting with. The people who pay the least now get the tightest throttle, and the exemption for Pro is explicitly time-boxed. Commenters on the r/OpenAI thread read it as a nudge toward the $100 and $200 plans rather than a neutral policy tweak, and it's hard to argue the incentive isn't there.
There's a second-order cost that one practitioner flagged: when limits, quotas, and pricing tiers move this often, it gets harder to build on top of any single provider. If you sell or deploy AI tooling for clients, a cap that appears in July, disappears mid-July, and reappears in late August turns into a budgeting problem as much as a usage one.
Who's exempt, and for how long
Right now the map looks like this. Plus at $20 gets the 5-hour cap plus the weekly quota. Pro at $100 and $200 gets the weekly quota only, with the 5-hour gate off "for the upcoming months." Enterprise and Edu sit outside on credits. The load-bearing phrase is "for the upcoming months." OpenAI has already shown it will flip this switch both ways inside a single quarter, so the Pro exemption is a current state, not a guarantee.

A short walkthrough of the coding-limit shift and the reasoning behind it.
What to do about it
If you're on Plus and you actually hit the wall, the honest question is whether you're paying $20 for a tier that no longer fits how you work. Jumping to $100 to escape one cap is a real cost jump, and it's worth checking whether you'd use the headroom or just feel better having it.
Before you upgrade a single provider, price out the alternative of spreading work across models. A lot of what pushes people into a higher OpenAI tier is capacity, not capability, and capacity is exactly what you can hedge by not routing everything through one plan. Our guide to cutting AI subscription costs covers when that math beats a straight upgrade, and the aggregator breakdown covers running several models under one roof so a single provider's cap stops being a hard stop.
If you code specifically, the capacity question is the same one that's been driving the Claude Code vs Cursor vs Codex comparison all year. The tool that lets you keep working when one provider throttles is worth more than a few benchmark points.
FAQ
Does the 5-hour cap apply to regular ChatGPT chat on Plus?
The announcement names Codex and ChatGPT Work specifically. It's aimed at the coding and agentic surfaces where a single session can burn a lot of compute, not casual chat.
Are the $100 and $200 Pro plans safe from this?
For now. OpenAI says the 5-hour gate stays off for Pro "for the upcoming months," which is a current exemption with a shelf life, not a permanent promise.
Wasn't this limit removed already?
Yes. OpenAI lifted the 5-hour cap on July 12 and left the weekly quota as the only constraint. This August 25 change puts the 5-hour window back for Plus.
Is this a price increase?
Not directly. The $20 price is unchanged. What changed is how much you can do inside it, which is a squeeze on value rather than a change on the sticker.
Should I upgrade to Pro because of this?
Only if you were already brushing against the weekly quota. If the 5-hour window is your only pain point, spreading work across models is usually cheaper than a five-times price jump. See our breakdown of what AI subscriptions really cost.
