Anthropic Updates Claude to Prevent Game Cloning

Anthropic has implemented changes to its Claude AI model to restrict the generation of direct video game clones. Engineering leader Addy Osmani confirmed that two sentences were added to the Claude Code prompt on Opus 5.5 to steer the model away from recreating specific intellectual property, citing company usage policies.

The update remains focused on preventing copyright infringement while still allowing the creation of original games and genre-based projects. The change was announced on October 30, 2026.
