That is very strange. I havent seen that. It sounds like something leaking from its system prompt or something that its not handling well. Anthropic trying to prevent it from running longer or something.

I definitely have. It's like something in the system prompt has "keep the well-being of the human in mind" and of course the date and time, but something makes the model take that way way too literally.

Personally I think it's due to context length.

Whenever context gets towards the max length is when I've noticed it.
