Citing Anthropic's official research page, a Reddit user notes that Anthropic's deployed anti-distillation defenses may have reduced the volume of training data harvested from its Claude models by 90–99%.

Anti-distillation defenses aim to stop competitors from distilling a frontier model's capabilities through mass querying. If accurate, the measures are highly effective in practice—and signal that the "train small models on scraped closed-model outputs" route is being systematically closed off.
