@Clashluke This is not true - we reverted that and only ever fall back loudly.

@Clashluke I think that's outdated, they got backlash because of exactly that, and then said "okok we'll loudly fallback or refuse instead", and that's what people are seeing now. Not me though.

@_sholtodouglas appreciate the correction, but it's still in the model card https://www-cdn.anthropic.com/d00db56fa754a1b115b6dd7cb2e3c342ee809620.pdf

@_sholtodouglas appreciate the correction, i'll take the post down
the screenshot is directly from the model card and beyond "more prompts stop chats" there seems little evidence of improved results
