What is the License of DragGAN?
They used StyleGAN in all of the demo videos, I wouldn't think this could be commercialized unless it works on other non-StyleGAN models too. StyleGAN license by Nvidia says they own 'all derivative works' and that a 'derivative work' is defined as one that is not independently functional from using StyleGAN.
So, yes, they could maybe release a commercial version of this, but the software would need to provide significant function outside of the use of StyleGAN. That or they would have to arrange a deal with Nvidia ahead of time.
This includes anyone that uses this when it is released. If it is limited to only using StyleGAN models, and this is used in a country where Nvidia's IP is enforced, they can sue you to take ownership if you use it for profit or in a way they don't like.
They historically have not done this, and you can probably adapt the approach yourself to another GAN architecture, but that is how I interpret this.
If I were the people releasing this, and I had intent to commercialize it, I'd release the full StyleGAN version like they show in the demo, and simply apply the same approach to an in-house adaptation of another GAN that has some performance improvements over StyleGAN, and sell that one. It'd generate a ton of hype, would be really popular with AI art fans (we can start digging in and start having non-commercial fun with it right away), and you'd have all the advertisement you need for years as people adapt the non-commercial StyleGAN based release in parallel while a commercially-viable non-StyleGAN variant that the developers maintain, can absorb those enhancements in parallel.
As @WyattAutomation pointed out, since the code is developed based on https://github.com/NVlabs/stylegan3, it will include the Nvidia Source Code License, which does not permit commercial use.
