Earlier quoted context omitted.
This is purely a function of everyone remembering the RIAA's decade-long campaign to prevent people from taking the music they had rightfully stolen. As far as I'm aware LLaMA was trained on "publicly available data"[0], not "licensed data". Furthermore, MusicGen's weights are licensed CC-BY-NC, which is effectively a nonlicense as there is no noncommercial use you could make of an art generator[1]. This is not only…
> MusicGen's weights are licensed CC-BY-NC, which is effectively a nonlicense as there is no noncommercial use you could make of an art generator How do you figure? Have you never just...made stuff to make stuff?
- If I use AudioCraft to post freely-downloadable tracks on my SoundCloud, I still get the benefit of having a large audio catalog in my name, even if I'm not selling the individual tracks. I could later compose tracks on my own and ride off the exposure I got from posting "noncommercially".
- If I run AudioCraft as a background music generator in my store, I save money by not having to license music for public performance.
- If I host AudioCraft on a website and put ads on it, I'm making money by making the work available, even though I'm not charging a fee for entry.
I suspect that a lot of people reading this are going to have different arguments for each. My point is that if you don't think that all of these situations are equally infringing of CC-BY-NC, then you need to explain why some are commercial and some are not. Keep in mind that every exception you make can be easily exploited to strip the NC clause off of the license.
If you're angry at the logic on display here, keep in mind that this is how judges will construe the license, and probably also how Facebook will if you find a way to make any use of their AI. The only thing that stops them from rugpulling you later is explicit guidance in CC-BY-NC. Unfortunately, the only such guidance is that they don't consider P2P filesharing to be a commercial use.
So, absent any other clarifications from Facebook, all you can do without risking a lawsuit is share the weights on BitTorrent.
EDIT: And yes, I have made stuff just to make stuff. I license all of that under copyleft licenses because they express the underlying idea of 'noncommercial' better than actual noncommercial clauses do.
