Their nematron 320b model was released on what essentially is an open source licence (available for commercial use except if you are doing shady things like spamming and collecting biometric data).
Having a robust open source ecosystem directly benefits Nvidia since they sell more higher end consumer GPUs.
Obviously, there’s a real chance that this isn’t open sourced since it’s a video model and there’s huge money involved. Doesnt really change the fact that having YouTube and Netflix dictate who gets to make video models and at what cost isn’t a good idea.
