One thing I read on this topic on reddit is never EVER use the word "girl" when prompting H3. So CSAM probably.
But I haven't seen anything reliable about H3 being particularly special in ther regard.
even a Chinese model that thinks its Claude when asked would have inherited this association
And no, including the word "girl" in H3 does not lead to CSAM in any way, shape or form, but it's a great example how FUD quickly spreads.
One thing that I had experience with, that led me to believe this might be true: it seems one of the earlier llama models was over-tuned to resist generating CSAM. Once I tried a somewhat sensitive prompt containing the word "girl" in it. Llama only ever generated refusals for this prompt, citing I was prompting for CSAM. GPTs and Claudes of that era had no issues with the same prompt.
