Nvidia and "open source" is like opposite things. Nvidia only ever opened stuff that helps their bottom line or improve vendor lock-in.
But yeah they are good shovel seller and competitor to actually evil companies that literally wants to eat all the world chips and energy supply.
In the open source space, the Nemotron models from nVidia are quite real. Including a Nemotron Ultra variety meant to be large enough for near-SOTA.
Nvidia not doing it out of goodness of their hearts and love to open source. If at anynpoint their CUDA vendor lock-in moat will faik because Intel or AMD manage to get working software they'll return to keep everything locked and proprietary ASAP.
Basically everything Nvidia does in open source is there to make sure their proprietary stack have a good moat and no competitor stack can catch up.
Strongly disagree: https://build.nvidia.com/models
Their license terms are also incredibly generous and allow commercial use, modification, etc, at no cost.
How soon do you think this generosity end if AMD or Intel or some chinese competitor would be able to provide price competetive hardware?
