An Anthropic research article states that early evidence shows its new distillation defense method reduces the amount of data obtained by distillers by approximately 90% to 99%, and the number of reasoning tokens extracted on the platform has dropped to 1/10 to 1/100 of the previous level. The defense falls into three categories: using preserved thinking to prevent new API accounts from editing Claude's prior context, and making reasoning records visible only to the organization that produced them; using a two-stage classifier to intercept extraction attempts, with a false positive rate below 0.1%; and tightening limits on and banning accounts that repeatedly attempt, with charges applied to intercepted requests starting September 24. Anthropic's official X account subsequently stated that over the past few months it has made clear progress in reducing the effectiveness of distillation attacks against Claude, and attached a link to the research article.
