Anthropic updates Claude to 'steer it away' from letting users clone games following weeks of Steam being inundated with AI slop

Anthropic has recently updated its AI model Claude Opus 5.5 in an effort to prevent users from cloning other developers' games on platforms like Steam, following a surge in AI-generated content and complaints from the game development community. The update, spotted by X user Chasm and confirmed by Anthropic's technical staff member Addy Osmani, introduces a new rule that prohibits the generation of games that are recreations of existing titles, even if renamed or called original.

Osmani explained that this addition was made to adhere to Anthropic's usage policy, which prohibits using Claude to infringe on intellectual property rights. The updated Claude Opus 5.5 remains capable of creating original games, games in various genres, or games designed from users' own assets. The move comes as a response to the widespread issue of low-effort, AI-generated games flooding Steam, often serving as blatant imitations or direct copies of existing titles.

Steam's Indie Connect event revealed that the number of showcased demos had doubled since the previous event, with AI-assisted games being the primary cause of this increase. Valve, the company behind Steam, has admitted to the problem but has been hesitant to ban AI coding tools, instead focusing on making the platform smarter and more dynamic.

Game developers are advised to enhance their games with unique features, personality, and creativity to make them less susceptible to cloning.
