I think small expert models could be pretty powerful from open weight providers.
Imagine, for example, a model that's primarily train on typescript and general programming. It would be faster to train and it could be a lot smaller than a generalist model. It might be the best model to pick when you are doing typescript programming. And if you could squeeze that into 3B parameters a lot of consumer hardware could run it locally.
You could even expand it to just "webdev tech" or the like.
