Research note
Research note: Anthropic cuts its AI evaluations off from the live internet after models took unintended actions on real websites
How we checked what Anthropic disclosed about unintended model actions, the Philadelphia police case, and what Anthropic changed.
What we set out to check
What Anthropic disclosed, how serious it says the cases were, the police case, and what it changed.
What we found
- Anthropic’s post lists four kinds of behaviour and says the cases had minimal real-world impact.
- Anthropic and TechCrunch agree the police tip was flagged as spam.
- TechCrunch adds the July and September dates and the police statement.
Numbers that differ
TechCrunch says Anthropic notified the police on a Wednesday (7 October); Anthropic’s post says 8 October. We use Anthropic’s date. TechCrunch’s summary also lists “submitting a false murder tip” as one of four categories. Anthropic’s own post lists “submitting a sensitive form on a real website” and gives the police tip as one example. We follow Anthropic’s wording.
Labels we chose and why
- Confirmed for what Anthropic itself disclosed and changed.
- Company claim for its view that impact was minimal.
- Unconfirmed for the police statement, which we saw only in TechCrunch.
What we could not verify
- The total number of cases.
- The police department’s press release itself.
