Anthropic has already been burned before on this. DeepSeek was trained on million of conversations with Claude. And DeepSeek created thousands of free accounts to burn all this compute at their expense.

And they're hilariously pissy about it for a megacorp that did the same with the entire Internet and every library book they could get their hands on.

Anthropic's claim was that Deepseek collected ~150k conversations.

I think the extent of distillation by Deepseek specifically is overstated. For comparison, Minimax collected over 13m 'exchanges', which starts to sound a lot more like large-scale distillation.
