Nvidia releases some of the most open open weights models, Nemotron 3, which have the full training code open, and most but not all of the training datasets.

Nvidia is a big company. They are good about some things and bad about others.

I think they really do like open weights because they make some of the best hardware for training, and the more open weights models there are, the more people are training and fine-tuning them, mostly on Nvidia hardware.

I feel like Nvidia is one of the better choices for buying Huggingface. Not perfect, but definitely far from the worst.
