- Claude now exceeds your 5-hour usage limits more quickly during weekday peak hours (5:00 a.m. to 11:00 a.m. PT)
- The change hasn’t been officially announced – it surfaced via an engineer’s post on X.
- Your weekly limits haven’t changed, but using Claude matters more than ever.
Anthropic is reducing message limits, even for Pro and Max customers during its peak hours, in a new effort to keep up with demand.
“To handle the growing demand for Claude, we are adjusting our 5-hour session limits for Free/Pro/Max subscriptions during peak hours. Your weekly limits remain unchanged,” said Thariq Shihipar, an engineer who works on Claude Code, in an article on X.
Unlike ChatGPT, which has a daily message limit, Claude operates in five-hour windows. Once you reach your limit in a five-hour window, you must use a less premium model or wait until the next refresh of your window to use it again.

An AI company changing the rules after you sign up is the kind of thing that usually causes a backlash from users, but it seems to happen quite often. OpenAI the abandonment of the AI Sora video generator without notice this week comes to mind as an example.
This time, however, it’s Anthropic that’s pulling the rug out from under its users by changing its rules regarding message limits.
To handle the increasing demand for Claude, we are adjusting our 5-hour session limits for Free/Pro/Max memberships during peak times. Your weekly limits remain unchanged. On weekdays, between 5:00 a.m. and 11:00 a.m. PT / 1:00 p.m. and 7:00 p.m. GMT, you’ll exceed your 5-hour session limits faster than before.March 26, 2026
Around 7% of users affected
Shihipar continues:
“On weekdays, between 5:00 a.m. and 11:00 a.m. PT / 1:00 p.m. and 7:00 p.m. GMT, you will exceed your 5-hour session limits faster than before.”
So if you’re in the Pacific Time Zone (PT), you may want to use Claude primarily in the late morning if you don’t want to exhaust your message allocation. For Greenwich Mean Time (GMT) users, it is best to avoid the afternoon and early evening.
If you live in another country, you will need to determine when Claude’s peak hours affect you.
According to Shihipar, “About 7% of users will hit session limits they wouldn’t have had before, especially at professional levels. If you’re running token-intensive background tasks, moving them to off-peak times will further stretch your session limits. »
Shihipar ends his series of tweets by saying, “I know it was frustrating. We continue to invest in efficient scaling. I will keep you posted on progress.”
Closely monitor your consumption
It seems curious to me that Anthropic let this announcement happen this way. It was quietly posted by one of his engineers on social media rather than from one of his official social accounts on X, or even through his website.
I understand that a company doesn’t want to shout bad news that might annoy customers, but this seems important, and it’s quite possible that many Claude users will simply ignore the changes.
Earlier this month, Claude temporarily usage rates doubled for all outside peak hours. On the other hand, this announcement was made via the official Claude sur X account, even if the increase in prices was only temporary, from March 13, 2026 to March 28, 2026.
Claude has always operated a pay-as-you-go system to get additional usage, provided you have a paid Claude plan (Pro, Max 5x or Max 20x), which allows you to continue working with Claude after you reach your plan’s usage limits. Details on how to enable this can be found on Claude’s website.
Practically speaking, the rule change means you need to start thinking more strategically about when you use your Claude account, especially since the time of day during peak hours varies significantly between countries.
This also means that we need to closely monitor how our AI companies deliver their services, because the boundaries are no longer set; they move.
