This comment here seems to summarize it well: https://github.com/deepseek-ai/DeepSeek-V3/issues/457#issuecomment-2627016777
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.
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.
