Screw Open AI for these terms. I hope there is a lawsuit so this gets ironed out in the court of law. It is so high and mighty for them to train on copyright material produced by other people without explicit consent but then to deny other people from doing the same thing.
If OpenAI wins, and successfully manages to stop alpaca/gpt4all type datasets, then they should be counter-sued for doing the same with upstream data.
At the end of the day proving in a court of law whether a particular LLM was trained from an open ai model derived dataset may also present to be very challenging if not impossible.
I for one would love to see more alpaca like datasets being used for commercial applications.
