## Summary

Anthropic has updated its Claude model to prevent users from generating AI recreations of specific, existing video games. The change was first spotted by an X user and confirmed by Addy Osmani, a member of Anthropic's technical staff. Osmani stated that the company wants to steer the model away from infringing on intellectual property, which violates its usage policy. The new code explicitly instructs Claude to build original games, genre-based games, or games based on user-provided designs and assets, while refusing requests to replicate specific titles, even if they are renamed.

This update arrives amid a surge in AI-assisted decompilation of AAA titles, with recent examples including Halo: Combat Evolved, Call of Duty: Modern Warfare 2, and Grand Theft Auto V being made available as browser-based fan projects. Anthropic has faced significant legal pressure regarding copyright in the past, including a $1.5 billion settlement with 500,000 authors over training data usage and a recent lawsuit filed by the estate of Elvis Presley. The company says it will continue to iterate on these restrictions to balance creative freedom with IP protection.

## Key points

- Anthropic updated Claude to refuse building recreations of specific existing video games.
- Addy Osmani confirmed the change aims to prevent IP infringement against usage policy.
- Original, genre-based, or user-designed games remain allowed under the new guidelines.

## Why it matters

This move signals a stricter enforcement of IP boundaries in generative AI, potentially impacting how developers use LLMs for game prototyping and addressing legal risks associated with training on copyrighted media.
