Valve previously implemented a rule that forced developers to disclose their use of generative AI in any games published on Steam. This new guidelines required developers to disclose generative AI use when it resulted in AI-generated content in the game itself—AI-generated images, textures, or 3D models, for example—or when the game was actively using AI to generate new content during gameplay. Now, Steam has apparently updated its generative-AI disclosure system (via Simon Carless on LinkedIn) to be clearer and to add nuance to the discussion, especially given the rise in popularity of AI code helpers and similar tools. Developers will still need to disclose all AI-generated content in their games, and Valve will still display the disclosure on the game’s Steam Store page.
