Leela Zero used some commercial providers for training. Mostly, we used the free offers for new GCP/AWS/etc members, so it's only a certain fraction of course.

To provide an order of magnitude: There are about 20m training games. Iirc a V100 could complete one game in something like a minute. So that's 300k-ish hours of value. Obviously, while V100 were the fastest, other GPUs were more cost efficient.
