> Do you understand that adult bodies and child bodies look different?

SD-based models can generate child bodies just fine, based on lots of training with non-porn images.

> Please show me a model trained on adult humans being fine tuned to generate a child human (fully clothed).

That's going to be hard in the SD space since there are, AFAIK, no models trained exclusively on adult humans (not even the base models), so you'd have to scratch-train a new base model to do this. (A model fine-tuned on adult images is still going to have the influence of base-model training, and unless massively overfit—usually very much an anti-goal, the exception being age-filter models whose entire focus is controlling apparent age [0]—will not have lost much of the generalization capability of the base model.)

The generalization abilities of models are good enough in other contexts that its plausible that realistic nude children could be generated by a model with no nude children in its training data that was otherwise trained on both clothed children and nude adults. I have no plans on testing this, however.

I have not stated anything contrary.

Stable Diffusion has failed me for much simpler interpolations than the one you're describing. I don't believe this would work based on previous interpolations I have seen in Stable Diffusion. You can convince me by showing an example, but not by stating that it is possible without one.

Its succeeded for me in much more complex ones. SD (even with the same exact set of checkpoint, LoRa, etc., and other workflow elements) isn't consistent across apparent-to-humans complexity levels in its generalization ability, and there are a very large combination of potential combinations.

Yeah, I'm not going to try to make simulated child porn for you, and while I would have sided with you in the debate over whether your earlier proof request amounted to a request for that, this one very clearly does.

Jesus, what is wrong with you? I clearly asked for an example of complex interpolations. How am I "very clearly" asking for CP when we're talking about complex interpolations, not CP?

Please, explain how I am "very clearly" asking for it. Please. Literally both sentences preceding the one you quoted (as in, the entire paragraph containing this sentence) are talking about interpolation. How do you jump from interpolation to CP??
