That's kind of the problem, isn't it? How do you know which part of the model to put in memory? You have to make a per-parameter decision of whether or not it's worth it to have it in memory or whether the value should just be treated as zero. Then you have to "re-link" the layers of the model to the new positions of each of the weights. For billions of parameters, that's a lot of calculations. And it requires us to know what each parameter actually represents, which nobody does.
