Artificial intelligence research company Anthropic has introduced advanced security measures to curb illicit model distillation attacks against its Claude models, reporting an estimated 90 to 99 per cent drop in data harvested by unauthorized entities.

The developments, detailed in an Anthropic blog post, address growing concerns over large-scale industrial campaigns designed to siphon proprietary reasoning capabilities from frontier systems to train competitor models without authorization.
