You already can with opensource models. Its kind of insane how good they're getting. There's all sorts of finetunes available on huggingface - with all sorts of weird behaviour and knowledge programmed in, if thats what you're after.

Do you mean each different AI model should have a preferences section for it? This might technically work too since fine-tuning is apparently cheap.

you can alter it with base instructions. but 99% won't actually do it. maybe they need to make user friendly toggles and advertise them to the users

Whould we be able to pick that PI == 4?

It'd be interesting if the rest of the model had to align itself to the universe where pi is indeed 4.
