Calls it “Deepsneak”, failing to make it clear that the reason people love Deepseek is that you can download and it run it securely on any of your own private devices or servers - unlike most of the competing SOTA AIs.
I can’t speak for Proton, but the last couple weeks are showing some very clear biases coming out.
I haven’t looked into Deepseek specifically so I could be mistaken, but a lot of times when a model is called “open-source” it really is just open weights. You can download it or train other models off of it, but you can’t actually view any kind of source code on how the model works.
An audit isn’t really possible.
