But I thought Nvidia “loves open source” (they don’t) and they are now a supporter for open source and open weight models by acquiring Huggingface? (They don’t actually care)

But the line is drawn when it involves CUDA and any part of their closed source compilers (nvcc).

There are obvious reasons why they are closed source, but it’s becoming pointless since Deepseek have open sourced their AI compiler and compute libraries with DeepGEMM and eventually they will catch up.

They only care because open-weight helps to drive the GPU business notably thanks to inference providers (Baseten, Together, Mistral, ...).

At least their support helps the open-weight ecosystem.

They certainly do _care_. Embrace, extend, extinguish.

Depends on which open source you are talking about, like every single company contributing to FOSS.

They care when the agendas align, and they don't when they won't.

They don't. I got threatened with a lawsuit after I suggested (submitted patches) they fix some of their buggy kernel code.
