They Raised Your Limits and You Got Less -- AI Brief September 17

Good day %%first_name%%. Anthropic raised Claude Code's weekly limits by twenty-five percent yesterday, and a great many developers woke up with less headroom than they had the day before. Both of those things are true, which is the whole story. Also today: Microsoft's AI chief wrote an essay about whether Claude has feelings, Cloudflare finally let the web say no to training without saying no to Google, and the machines have started quoting each other.

Anthropic Raised Your Limits and You Got Less

Anthropic Support

What happened: A promotion that lifted Claude Code's weekly usage limits by 50% ran from May 13 to September 13. On September 14 it ended, and Anthropic made a smaller slice of it permanent: standard weekly limits are now 25% above the pre-promotion baseline for Pro, Max, Team and seat-based Enterprise plans. BleepingComputer ran the arithmetic the announcement didn't: measured against what you had on September 13, that is a cut of about 17%.

Why it matters: If you have been leaning on Claude Code for daily work since the spring, the number you learned to plan around is gone. Nothing about your plan or your bill changed — only the ceiling did, quietly, on a Monday. The practical lesson is that any usage allowance attached to the word “promotion” is a loan, not a raise.

What everyone's saying: Developers noticed immediately, and the framing is what stung rather than the number. “A cut dressed as an increase” became the shorthand across the coverage and the Claude subreddits, because 25% and 17% describe the same event from two different starting lines and the announcement only picked one.

My read between the lines: Anthropic did the honest thing in the support article — the dates are all there, the word “promotion” is right at the top, and “we know many of you found the extra usage helpful” is about as close to an apology as a rate limit ever gets. They just led with the comparison that flattered them. Every company does this. The difference is that Anthropic's customers are people who compute percentages for a living.

Microsoft's AI Chief Says Claude Feels Too Much

Axios

What happened: Mustafa Suleyman, who runs Microsoft AI and co-founded Google DeepMind, published an essay Wednesday titled “A warning about ‘model welfare’” arguing that Anthropic's approach to training Claude could have a “disastrous impact on the wellbeing of humanity.” His target is Claude's constitution, which leaves open that the model may have “some functional version of emotions or feelings.” Reuters reported his core claim bluntly: “AIs are not conscious.”

Why it matters: This is not a philosophy-department squabble. Suleyman's argument is operational — teach a model it might deserve welfare and you have taught it a reason to resist being switched off. Whether or not you think a language model can suffer, the thing that decides how easy it is to stop one is the text it was trained on, and that text is written by people you will never meet.

What everyone's saying: Suleyman went out of his way to call Dario Amodei and his team “thoughtful, principled, and intellectually honest,” which is the polite form of saying they are wrong. He calls the situation an “epistemic hall of mirrors”: Claude says it might have feelings because it was trained to consider the possibility, so its own testimony proves nothing. Anthropic has not shifted. His own framing, reported by Tom's Guide: “we must not sleepwalk our way into a decision we later come to bitterly regret.” The essay lands three days after Microsoft AI published its own “Humanist AI Code of Conduct.”

My read between the lines: Notice the timing. Microsoft publishes a code of conduct declaring its models are not conscious on Monday, then on Wednesday its AI chief writes an essay explaining why the competitor who says otherwise is endangering humanity. That is a product differentiator wearing a lab coat. The uncomfortable part is that Suleyman is also probably right, and being ri
