Nah, nobody's begging for people to A) come use time on their GPUs B) come watch them train their biggest models. Nor does it make sense to spend $X00M training a big model using an experimental technique before you announce it, nor does it make sense to hold back breakthroughs as an academic until someone commercializes it at scale. Category error.
I do ML research at a small industrial lab. I’ll gladly provide some compute to people with a cool idea if that results in my company name listed on a paper in a top conference. Especially if the people are from a top university.
