Thibault “Tibo” Sottiaux, OpenAI’s engineering lead for Codex and ChatGPT, announced tonight that a five-hour usage limit is returning to Codex and ChatGPT Work for Plus subscribers starting tomorrow (25).

After users reach either the five-hour or weekly limit, they can either wait for their usage to reset for the next cycle or purchase additional credits. OpenAI also occasionally resets users’ limits for free, while banked resets can be earned through certain promotions and referral offers.

Over the past few weeks, however, OpenAI temporarily lifted the five-hour usage limit for Codex and ChatGPT Work, leaving only the weekly cap in place.

During this period, the company also reset users’ weekly usage early on several occasions to celebrate milestones, including adding another million active users across the two (now unified) platforms.

However, as Tibo explained tonight on X:

Tomorrow we will bring back the 5h limit for Plus accounts across ChatGPT Work and Codex. I had mentioned this a while ago, but then postponed it.

This is necessary as (a) the 5h limit allows us to smoothen the load on our compute, allowing to keep the plan generous in terms of weekly usage and (b) users on the Plus plan are relatively casual and new users, but then also just accidentally eat through their whole weeks usage and then are confused, making it not a great experience.

We are for the upcoming months keeping the 5h limit not enabled for Pro $100 and Pro $200 subscriptions.

Tibo did not mention any changes for Enterprise or Edu accounts, which currently use a separate credit-based usage system.
