Anthropic PBC said it uncovered a group in northern Yemen, where Iran-backed Houthi militants operate, using its Claude AI model to support development of missile and rocket systems, according to a Bloomberg report summarized by Techmeme.

The finding adds to concerns about advanced AI use in military programs and by non-state actors. The source describes the group's location and the reported use of Claude but does not detail how the model was accessed, how long the activity continued, or what Anthropic did in response.

The account is Anthropic's own disclosure rather than an independent verification.
