Could it be because Claude / ChatGPT are the most viral models and thus are more likely to be in the training set so when someone asks "Which AI are you?" the likeliness of Claude and ChatGPT being a reasonable answer is higher?

replyIt has been observed again and again that ChatGPT and Claude would identify themselves as DeepSeek when asked in Chinese, through the API without a system prompt to solidify their identities. I don't think identity is a good evidence for distillation.
