IT Home reported on October 31 that gaming outlet gamedeveloper published an article today (October 31) saying Anthropic has restricted the Opus 5.5 model in its AI coding tool Claude Code from helping users recreate specific existing games.
Developer @chasmmmmmmmmmmm posted on X yesterday (October 30), saying that around October 27, Claude Code added a rule for the Opus 5.5 model that cannot be turned off:
It may create original games, games in a particular genre, and games based on the user's own designs and assets; it may not recreate a specific existing game, even if it is renamed or described as original.
Anthropic technical staff member Addy Osmani subsequently responded that the company had added two sentences of guidance to Claude Code's prompt to prevent it from “recreating other people's specific games.” He stressed that using Claude to infringe intellectual property violates the platform's usage policy, while original games, genre-based games, and games developed using one's own assets remain permitted. IT Home included the relevant screenshot below:
Based on currently public information, the restriction on “recreating specific existing games” has been explicitly identified only for Claude Code with the Opus 5.5 model. Anthropic said it added “two sentences of guidance” to the Claude Code prompt for Opus 5.5 to keep the model from recreating other people's specific games. The report did not say that Anthropic had extended the same rule to other Claude models or all versions of Claude Code.
