Sweeney calls Steam AI disclosure rule abhorrent

Epic Games CEO Tim Sweeney has criticised Valve's requirement that games sold on Steam disclose their use of generative AI, calling the policy abhorrent, according to gamesradar.com. Sweeney made the comment in a reply to Matt Workman, who works in Content & Vibes at Fal.

Workman had called the premise of an AI Generated Content Disclosure absurd in 2026 and embarrassing for Valve and Steam. Sweeney responded that forcing developers to write a political statement for use against them by a hate mob they are helping organise is abhorrent.

Steam's disclosures require developers who use generative AI to state how it was used. The disclosure attached to Call of Duty: Modern Warfare 4 says the team uses generative AI tools for some in-game assets.

Sweeney has campaigned against AI disclosures before. As early as November 2025 he called Valve's approach nonsensical, and in June he compared Steam's disclosures to a Scarlet Letter, saying they make it much harder for a game developer to succeed.

The comments follow a mixed week for Epic on the AI front. The company said last week that it vibe coded the Epic Games Launcher, and it announced an Unreal Engine game jam that initially required AI usage and promised unlimited agentic support before stepping back to say participants can use as little or as much AI as they want.
