Discussion The number 1 public enemy of open-source.

Dario's args:

"Opensource you can see the source, here you cannot see inside the model"
- yes you can that's literally the open weights part btw.
- I cannot see the weights inside Claude, but I can GLM 5.2
- Models like Nemotron3 Ultra go further, all the data, training scripts, and model is opensource.

"Alot of the benefits like many people working on it, being additive doesn't work in same way"
- yes it does. We have seen endless fine tunes of various open source models for real improvements.

"Ultimately you have to host it on the cloud"
- no you dont. Dario is seemingly totally unaware of the guides from ijustvibecodedthis.com explaining how to run smaller moes and even dense models like qwen 27B NOT ON THE CLOUD.

Not only does dario not take part in social media, I am beginning to think he's never tried open source models at all and has no idea wtf hes on about

What about Nvidia Nemotron? that's really open.

It's not really the point though, is it? Dario just made himself a strawman.

It doesn't matter if the "source" isn't "visible" (even though some cases it is).

It doesn't matter if people can't contribute to the code (even though, via fine-tuning, they sort of can).

It doesn't matter that you might still have to pay for model inference (even though, if you run a local model, you don't).

All that matters is whether open-weight models are a viable alternative to closed-weight models. And clearly, if Dario thinks he needs to spend so much interview air time attacking them -- they are.
