Valve has updated its guidelines for developers publishing on the popular PC platform, specifically addressing AI disclosure and requiring developers to notify gamers if AI was used throughout development.

The changes were spotted by Simon Carless, the founder of GameDiscoverCo, which he outlined in a new report. According to Valve, developers aren't required to publish an AI disclaimer if AI-powered tools were used to help create the game. This is specifically in relation to code-aiding software. However, when it comes to generative AI, Valve requires developers to provide a disclaimer if generative AI was used to generate content for the game.
This requirement also covers any marketing material for the game and the Steam landing page for the title. Additionally, Valve requires developers to add a disclaimer if the title has "AI content generated during gameplay," which covers "images, audio, text, and other content." Ultimately, it will be up to the players to determine if AI content disclaimers are warranted or not, especially considering the ubiquitous nature of AI-powered tools assisting all kinds of software engineers, not just game developers.
