Hi there! Good question, it's one I get a lot and don't mind.
First off, I am not a lawyer but have consulted them. A lot of this is a gray area and not well defined. As you mention, there is the code, the given models, models fine-tuned on those models, models trained from scratch, using styelgan reimplementations, etc. Even with the license being included there does not mean that the output of a model trained from scratch counts as derivative work. And technically I just sell things like upscaling, keeping images private, google sync etc and provide unlimited image creating for free (not sure if that would hold up in court but I think it's relevant). So, no I do not think I am violating the license. But some lawyers may feel differently.
Also, I try hard to cite everything involved. Google was thrilled by my use of the biggan model and how it showed off the model. With the amount of money I have spent on Nvidia cards, I hope they are happy too :)
and then image ownership is a whole other question. Everything in arbreeder is CC0 to keep things simple https://artbreeder.com/terms.pdf
Are you saying that Artbreeder is using a model trained from scratch?
If so, was that a recent change? When I checked several months ago, your latent space sliders were compatible with nVidia's FFHQ model: https://news.ycombinator.com/item?id=23149739
The only explanation seemed to be that Artbreeder was fine-tuned from nVidia's released FFHQ model.
To rephrase the question: It seems like you were using nVidia's model (or a fine-tuned version) at some point in the past. At the time, you were also selling subscriptions via your pricing page. Do you just sort of ignore the legal implications and hope that it never becomes an issue?
