Valve Has 'Significantly' Rewritten Steam's Rules For How Developers Must Disclose AI Use (videogameschronicle.com) 1
Valve has substantially overhauled its guidelines for how game developers must disclose the use of generative AI on Steam, making explicit that tools like code assistants and other development aids do not fall under the disclosure requirement. The updated rules clarify that Valve's focus is not on "efficiency gains through the use of AI-powered dev tools."
Developers must still disclose two specific categories: AI used to generate in-game content, store page assets, or marketing materials, and AI that creates content like images, audio, or text during gameplay itself. Steam has required AI disclosures since 2024, and an analysis from July 2025 found nearly 8,000 titles released in the first half of that year had disclosed generative AI use, compared to roughly 1,000 for all of 2024. The disclosures remain voluntary, so actual usage is likely higher.
