Being able to learn within context, without updating weights is amazing. Imagine how much more efficient and/or powerful it could be if we found a way to update the weights in real time.

Maybe even more powerful would be reducing the number of examples needed to learn, eg less than one shot

updating weights in real time is useless if each update basically does nothing because it takes an insurmountable amount of training, on the other hand if i can give my model a succinct “lesson” i’d then be very willing to wait a while for it to “process”

As I understand, that's basically what fine-tuning is?

What sort of performance difference can you expect from in context Vs fine tuning, any relevant papers on this ?

Yeah, that's why just updating the weights on the models such as they are doesn't work. But they're right that it's desirable to have some sort of online learning, whether on top of a frozen language model, or through some not yet invented way to do it end to end.

Yeah I've been thinking about that a lot within the context of self-driving cars. What if we could take the rare but significant examples of model confusion, and then... explain to the model what it did wrong just as we would to a human. If it could then incorporate that information into future weights, that would be game changer in a LOT of fields where it's been hard to bridge the gap.
