If you have openrouter do this little experiment: Go to https://openrouter.ai/chat https://openrouter.ai/chat. Select a few models, but customize them to have an empty system prompt.

The second time around Sonnet said it was Anthropic Claude. Are Chinese companies currently complaining about Anthropic distilling their models?
