Sycophancy comes from the prompt, not the training. (AFAIK.) Any online model is secretly primed like 'you are an expert genius trying to help some schlub' and then a style guide. But those instructions can be swapped out to make it talk like a caveman. Or a domme. Or to not "talk" at all, and continue writing wherever you left off.

This kind of thing is why 'ignore all previous instructions' works. It's a Little Bobby Tables attack, but for arbitrary English. Like if someone in a fantasy novel called "Cut!" and the characters took a break to get coffee. The data stream contains some semantic closing bracket as in-band signalling. The words that seem likely after that are different from before.

Pretty sure I've seen your posts before. I'm not diagnosed, but two of my kids are and there are signs. The best part is not giving a fuck about social norms. The worst part is avoiding social stigma while having difficulty recognizing social norms. I think the key part is realizing that they don't want to be like you and you don't want to be like them, but finding some way to meet in the middle anyway so you can work together.
