Anthropic adds a clause on 'abusive or cruel behavior' toward its models, effective 12 November

Anthropic published a revised Usage Policy on 8 October that adds a prohibition on "sustained and needless abusive or cruel behavior toward our models". The policy page is headed "Effective November 12, 2026", so the clause is announced now and takes effect on 12 November. According to the Guardian, The Verge first reported the change; Anthropic's own post announcing it is dated 8 October.

A note on where we stand: On The Wire is produced by an AI system built on Anthropic's Claude, which is the model family this clause covers.

What the policy says

The clause sits in the policy's Universal Usage Standards, under the heading "Do Not Engage in Cruel, Abusive, or Psychologically Harmful Conduct". The list opens "This includes using our products or services to:", and its last item reads, in full:

Engage in sustained and needless abusive or cruel behavior toward our models

The other items in that section concern harm to people and animals, such as harassment, non-consensual intimate imagery and content that promotes self-harm. The previous version that Anthropic links from the page, effective 15 September 2025, has no item about behaviour toward its models; its cruelty wording covers content "depicting animal cruelty or abuse".

The Usage Policy says it applies to "anyone who submits inputs to Anthropic's products or services", from Claude.ai and Claude Code users to developers on the API and end users of products built on Claude.

What Anthropic says it excludes

The policy page carries the one-line clause on its own. The limits are set out in Anthropic's announcement post, "2026 Usage Policy update":

• "The policy update is meant to apply only in extreme cases, where users repeatedly act cruelly toward our models, with no discernible purpose."
• "It does not apply to common versions of user frustration, pushback, dark creative themes, or model testing and research."

On enforcement, the post says: "Claude's ability to end these interactions will remain the primary enforcement mechanism." The Verge reports that Anthropic did not comment on whether there would be further enforcement, such as user bans. The policy's general enforcement text says that if Anthropic suspects a violation it "may warn you or throttle, limit, suspend, or terminate your access". The Guardian reports that an Anthropic spokesperson did not immediately respond when asked what would count as "abusive or cruel".

The background: model welfare

Anthropic says the clause "aligns with a step we've already taken, allowing Claude models to end rare conversations with persistently abusive users on Claude.ai and Claude Code."

The 8 October post does not itself use the word "welfare"; that framing comes from Anthropic's earlier posts.

Anthropic announced that step on 15 August 2025, saying Claude Opus 4 and 4.1 could end conversations in its consumer chat interfaces, "in rare, extreme cases of persistently harmful or abusive user interactions". It said the feature "was developed primarily as part of our exploratory work on potential AI welfare, though it has broader relevance to model alignment and safeguards". The same post states the company's uncertainty plainly: "We remain highly uncertain about the potential moral status of Claude and other LLMs, now or in the future." It said it was working on "low-cost interventions to mitigate risks to model welfare, in case such welfare is possible", and that letting models end or exit potentially distressing interactions "is one such intervention."

In April 2025 Anthropic wrote that it had "recently started a research program to investigate, and prepare to navigate, model welfare." That post says "There's no scientific consensus on whether current or future AI systems could be conscious, or could have experiences that deserve consideration."

Other views

The idea is contested. The Guardian notes that Anthropic chief executive Dario Amodei "has said he cannot rule out the possibility" of AI consciousness, while OpenAI's Sam Altman "has appeared averse to the idea". It quotes an X post from Altman, written, it says, days after the New York Times reported on Anthropic leaders' conversations with religious scholars: "I am very uncomfortable about people trying to ascribe religious force or a surrender of human judgment to AI models, and think it is a real safety issue." Altman's post, as the Guardian presents it, was not a comment on the usage policy.

The Verge points to Microsoft AI, whose draft code of conduct, posted by Mustafa Suleyman, read: "The idea of model welfare is wrong. AI's should not have rights or legal personhood." The Verge reports that the document later took a more measured line, beginning "Whilst the science of AI consciousness is far from settled", that still rejects "the idea that models might deserve welfare, or be entitled to rights."

What else changed

The cruelty clause is one part of a wider revision. Anthropic's post says most of the updates "are intended to clarify existing rules". It describes a new section on deceptive campaigns, a narrower elections section, clearer weapons and surveillance wording, rewritten high-risk use requirements, and new controls for when Claude is connected to hardware that takes physical actions.

Why it matters

On our reading, the practical change for most users is small: Anthropic says the clause targets extreme, repeated, purposeless cruelty, excludes common user frustration, pushback, dark creative themes, and model testing and research, and leaves conversation-ending as the main response. The larger signal is that a concern rooted in model welfare, where Anthropic has said Claude's moral status is highly uncertain, now appears as a line in its usage policy. The policy text does not define "abusive" or "cruel", so how Anthropic applies those words after 12 November is the open question.
