Frontier AI models · AI coding
Anthropic confirmed new prompt instructions added to Claude Code with Opus 5.5 to prevent users from recreating specific existing video games, aiming to mitigate copyright infringement risks.
Addy Osmani, head of developer tools at Anthropic, stated that new instructions were added to Claude Code prompts paired with Opus 5.5, directing users to build original games, genre games, or projects using their own designs rather than recreating specific existing games. The update follows instances where commercial titles and software tools were recompiled or reproduced using AI models. Community analyses noted that the prompt-based restriction primarily targets direct 1:1 remakes and may be bypassed by avoiding explicit naming or altering frameworks.
