Another one of these daily reminders that we live in a two-tiered justice system, everything you ever created is fair game to them, but don't you dare use a leak of their weights lest you want to be thrown in jail.
According to OpenAI you're not even allowed to use GPT output to train a competing model, so they believe that AI models are the only thing worthy of protection from being trained on. Llama used to have a similar clause, which was partially walked back to "you must credit us if you train on Llama output" in later versions, but that's still a double standard since they don't credit anything that Llama was trained on. For obvious reasons now we know that Zuck personally greenlit feeding it pirated books.
Well that hasn't stopped Deepseek.
Honestly, good for them. This whole "we can use your output for our input, but don't even think about doing the same" is just absurd.
