Claude Code's weekly limits drop 17% on 14 September, even though Anthropic called it a 25% increase

The announcement came from Anthropic's @ClaudeDevs account on X, not a blog post or a support-page update. The first post read: "Starting September 14, we're permanently raising standard weekly limits in Claude Code by 25% for Pro, Max, Team, and seat-based Enterprise plans. Until then, the current 50% increase will be in place." BleepingComputer reported that the post was deleted and replaced after criticism mounted, a detail other outlets like Notebookcheck covered without confirming the deletion specifically; whether it was a literal delete-and-repost or a same-thread follow-up, the substance is not in dispute, since the second post's text is consistent across every source that quotes it: "Compared to today, this works out to a 17% reduction in weekly limits on Claude Code. We're working on exciting changes that will make it feel like you're getting more from Claude, while having more visibility and control of your usage."

The exact math behind "25%" and "17%"

Index the original, pre-boost standard weekly limit at 100. The temporary summer boost took it to 150 (100 × 1.5). The permanent level starting 14 September is 125 (100 × 1.25). From the 150 users have had since May down to the new 125, that's a drop of 25 out of 150, or 16.7%, which every outlet reporting this rounds to 17%. From the original 100 up to the new 125, that's a genuine 25% gain. Both percentages describe the same 150-to-125 move; they just measure it from different starting points. The arithmetic checks out cleanly across every primary source, so this isn't a case of Anthropic's numbers being wrong. The complaint is that the announcement led with the flattering comparison and left the reader to notice the other one.

The full timeline: one boost, extended four times

• 6 May 2026: Anthropic separately, permanently doubles Claude Code's *5-hour* rate limit and announces a new SpaceX compute deal. This is a different limit from the one changing in September; more on that below.
• 13 May 2026: the temporary +50% weekly boost begins, a week after the 5-hour change above.
• Mid-July 2026: the boost, originally slated to expire around 13 July, gets its first extension.
• Through 19 August 2026: second extension, confirmed in an @ClaudeDevs post at the time.
• Through 31 August 2026: third extension: "We hope to make this a permanent change to our plans, but strong demand for our models means that capacity may be tight over the coming weeks."
• 29 August 2026: fourth and final extension, through 13 September, announced in the same post that revealed the permanent 125-index level taking over on the 14th.
• 13 September 2026: the boost ends.
• 14 September 2026: the permanent +25% level takes effect.

Does this touch Claude.ai chat too, or only Claude Code?

The 25%/17% change itself is Claude-Code-specific. Anthropic's general support page, screenshotted above, states that "your usage of all different Claude product surfaces (claude.ai, Claude Code, Claude Desktop) counts towards the same usage limit" — but that page is a generic explainer, revision-dated 13 July, and doesn't mention the September change at all. Treat it as background context, not confirmation that the shared-pool mechanic still works identically under the new 125-index number: neither the 29 August post nor the help center spells out how the September change interacts with cross-surface usage, which is a gap in the official record, not something this article can resolve.

Is this the same as May's 5-hour rate-limit doubling? No

It's easy to conflate this with a different, genuinely positive change from the same week in May: on 6 May 2026, Anthropic permanently doubled Claude Code's 5-hour rolling rate limit for Pro, Max, Team, and seat-based Enterprise, funded partly by a new compute deal for SpaceX's Colossus 1 datacenter capacity. That change is untouched by the September update. What's changing now is a separate, longer-window metric: the *weekly* cap layered on top of the 5-hour window since August 2025. If you track only one number from this article, make it this: your 5-hour limit isn't moving on 14 September. Your weekly limit is dropping from where it's stood since May, even though it's still higher than it was a year ago.

What developers actually said

The most-cited public reaction came from Theo Browne (t3.gg), who replied on X: "Hey Anthropic. You guys have given me a lot of subsidized compute. In return, I'll give you an example of how to make announcements like this without burning all your good will with developers," then sketched a transparent version of the same post, opening with the May promotion instead of the permanent-increase framing. His critique was about disclosure, not the math. On Hacker News, commenters independently worked through the same 150-to-125 arithmetic before Anthropic's follow-up post confirmed it. Anthropic hasn't given an on-record reason for the change beyond "exciting changes... coming" for usage visibility, with no specifics or date attached.

What to actually do before 14 September

• Check your current usage now, so you have a real baseline before the cutover: run /usage inside Claude Code for a breakdown, or check the rate_limits.seven_day and used_percentage fields in the CLI's status-line JSON output.
• Don't assume this only affects heavy users. Anthropic's general usage-limit documentation says Claude Code shares a pool with claude.ai chat and Claude Desktop on the same account, though it doesn't confirm how that interacts with the new September figures — if you also chat heavily on the same login, that usage still counts against the same weekly cap.
• If you're a sporadic user, price out API pay-as-you-go as an alternative to a seat plan; whether that's cheaper depends entirely on your actual weekly usage, which the /usage check above will tell you.
• Front-load heavy work before 13 September if you have a large refactor or migration planned, since that's the last day of the boosted 150-index limit.
• Check Anthropic's support pages closer to the date for the authoritative numbers rather than relying only on the announcement's percentages, since a support page dedicated to this specific change may publish exact figures the X posts didn't.

People also ask

When does Claude Code's weekly limit actually go down?

The boosted (150-index) limit ends 13 September 2026. The new, lower permanent limit (125-index, still 25% above the original pre-May baseline) starts 14 September 2026.

Is this a 25% increase or a 17% decrease?

Both, depending on the comparison point. It's a 25% increase over the original baseline from before May 2026. It's a 17% decrease from the temporarily boosted limit users have had since 13 May 2026. Anthropic's initial announcement stated only the 25% figure; a follow-up post added the 17% figure after public criticism.

Which plans does this affect?

Pro, Max, Team, and seat-based Enterprise plans. The Free plan doesn't include Claude Code, so it isn't affected; consumption-based (usage-metered) Enterprise seats bill per token and were never on the weekly-limit system either.

Does this change Claude Code's 5-hour rate limit too?

No. The 5-hour rolling rate limit was permanently doubled back on 6 May 2026 in a separate announcement and isn't part of this September change. Only the weekly limit is affected.

Does this affect Claude.ai chat or just Claude Code?

The percentage change is specific to Claude Code's weekly allowance, but per Anthropic's own support documentation, usage across claude.ai, Claude Code, and Claude Desktop on the same account draws from one shared usage limit, not separate pools per surface.

Did Anthropic delete its original announcement?

BleepingComputer reported that Anthropic's original post was deleted and replaced after a Community Note and developer criticism; other outlets covered the backlash without confirming the deletion specifically. The exact mechanics (a deletion versus an in-thread follow-up) aren't independently confirmed here, but the wording of the follow-up post, which explicitly states the 17% reduction, is consistent across every source that quotes it.
