Valve made an official statement, which PC Gamer (and others) have reported on. https://www.pcgamer.com/valve-is-scrutinizing-games-with-ai-assets-on-steam-says-avoiding-copyright-violation-is-the-developers-responsibility/ https://www.pcgamer.com/valve-is-scrutinizing-games-with-ai-... > In its statement to PC Gamer, Valve said that "The introduction of AI can sometimes make it harder to show a developer has sufficient rights in using AI to create assets, including images, text, and music. In particular, there is some legal uncertainty relating to data used to train AI models. It is the developer's responsibility to make sure they have the appropriate rights to ship their game. > We know it is a constantly evolving tech, and our goal is not to discourage the use of it on Steam; instead, we're working through how to integrate it into our already-existing review policies. Stated plainly, our review process is a reflection of current copyright law and policies, not an added layer of our opinion. As these laws and policies evolve over time, so will our process."
