The most they could do is try to arbitrarily make the licenses null and void, but there's no functional way to outlaw making code publicly available without also outlawing the entirety of HTML, CSS, and JavaScript.
Unfortunately, as I've learned recently, it doesn't look like Deepseek is actually open source.
You can download the model, but unless I'm misunderstanding, that feels comparable to calling Photoshop open source because you can download the .exe file on your computer.
Its MIT licensed. Meaning the code is open but the license is permissible in that copy's can be subsequently closed. This is unlike with the GPL most generally associated with open source code.
It's more open-sourced than I thought, but also seems debatable. I don't know enough about LLMs to properly judge. I would probably stay away from calling it "completely open-sourced" though.
Fair, but they gave quite a bit when compared to other leaders in the space such as "open"ai. I'm exciting for this project I stumbled across - https://github.com/huggingface/open-r1. There are gaps in what deepseek provided but others are trying to fill them in.
Of course! I think I've been particularly cynical about stuff being named open source because of OpenAI.
I use LLMs through Perplexity and GitHub CoPilot all the time, but I'm still too spiteful and petty to use anything from "Open"AI. I've been very happy with R1 so far.
