Anthropic confirms it’s been ‘adjusting’ Claude usage limits

If it feels like you’ve been hitting your Claude usage limits much more quickly over the past week, you’re absolutely right.

Anthropic has confirmed that it has been “adjusting” the five-hour usage limits for Claude Free, Pro, and Max users during the peak hours of 5 a.m. to 11 a.m. Pacific time on weekdays, while leaving overall weekly limits unchanged.

The news comes via a Reddit post from an Anthropic representative. I reached out to Anthropic and confirmed the post is authentic.

The Anthropic post doesn’t specify when the usage limit adjustment took place, but my understanding is the new rate limits kicked in on Monday.

Claude users have been complaining bitterly about how quickly they’ve been hitting their usage limits over the past week or so, and many had suspected a silent reduction in their five-hour usage allotments. Turns out they were right.

Anthropic says it imposed the adjusted usage limits to “manage growing demand for Claude.”

“We’ve landed a lot of efficiency wins to offset this, but ~7% of users will hit session limits they wouldn’t have had before, particularly in Pro tiers,” the Anthropic post continues. “If you run token-intensive background jobs, shifting them to off-peak hours will stretch your session limits further.”

Anthropic acknowledged that the limit adjustment “was frustrating” and that it is “continuing to invest in scaling efficiently.”

Word of Anthropic throttling peak usage limits comes amid a surge of interest in Claude following its legal standoff with the Defense Department, which has sought to tag Anthropic as a “supply chain risk” after the company balked at signing a military contract. A judge recently stayed the Pentagon’s move to apply the “supply chain risk” label.

Anthropic’s move to adjust its five-hour usage limits speaks to a bigger issue: how the big AI providers treat subscribers on flat-rate plans.

In the past, AI users on “plus,” “pro,” or “max” plans (which cost anywhere from $10-250 a month, depending on the provider) rarely hit usage limits because they were simply chatting with models in a web-based chatbox.

But with the rise of agentic AI functionality such as vibe-coding applications and “computer use” abilities, flat-rate AI subscribers are burning far more tokens than ever before, and the big AI providers are struggling to keep up with the demand.

The problem is exacerbated by Claude’s enormous one-million token context window, which was rolled out earlier this month.

What’s happening now is that Anthropic and other AI companies are hitting the brakes on flat-rate usage, sometimes silently. 

And no, it’s not cool.
