What is the weekly reserve limit for ChatGPT? Does anyone know?
Does this mean the limit is doubled? Is it also a regular limit?
I saw it in the backend too—waiting here for someone who knows the specific calculation rules to explain.
Thought for 14s
The gpt-reserve weekly limit shown in your image can be understood as a “backup weekly allowance.” It and the regular “weekly limit” are two separate allowances.
Simply put:
Regular weekly limit: the primary allowance you consume when using Codex / ChatGPT Work normally, which can be used with the standard models included in your plan.
gpt-reserve weekly limit: a fallback allowance pool provided to some accounts after the primary allowance is restricted or exhausted. The official name for it is currently Luna Reserve, and its main purpose is to let you downgrade to GPT-5.6 Luna and keep working. It cannot restore your regular allowance or let you continue using higher-tier models such as Sol without limits.
They are tracked and reset separately, so it’s quite possible for the regular weekly limit to have dropped significantly while gpt-reserve is still at 100%, and for their reset dates to be different. The 100% / 09/09 07:13 shown in your screenshot indicates the remaining amount and reset time for this backup pool itself.
Reserve isn’t available to every account. It’s currently being rolled out gradually to some Plus / Pro accounts, mainly for Codex and ChatGPT Work.
So you can think of it like this:
Regular weekly limit = main fuel tank
gpt-reserve = backup fuel tank, but the backup fuel can only let you drive “the Luna car”
Therefore, its greatest value isn’t “doubling your regular weekly allowance,” but preventing you from having to stop working completely once the primary allowance is used up.
If you’d like, I can also explain the specific order in which the “5-hour limit, regular weekly limit, and gpt-reserve” are consumed. Thought for 14s

Plus Users: The GPT-5 series Thinking inference model and the o3 model have a basic weekly limit of 3,000 uses per week. The o3 model alone has a weekly limit of 100 uses. The Work+Codex Agent mode shares a separate reserved weekly quota.
Team/Business Users: The GPT-5 Thinking model’s weekly limit is also 3,000 uses per week, with support for custom quota adjustments. Compared to regular Plus users, Team/Business users enjoy more flexible quotas.
Pro Users: Most advanced inference models do not have a hard weekly limit; restrictions are only triggered in cases of extreme high-frequency abuse.
I haven’t heard anything about the quota being doubled.
So isn’t this reserve weekly quota extra?
This answer is very detailed 
Regular weekly limit: The main quota you consume when using Codex / ChatGPT Work normally, which can be used for the standard models included in your plan.
gpt-reserve weekly limit: A fallback quota pool available to some accounts after the main quota is restricted or exhausted. The official name is currently Luna Reserve. It mainly lets you downgrade to GPT-5.6 Luna and keep working. It cannot restore your regular quota or let you continue using higher-tier models like Sol indefinitely.
