## Summary

Epic Games has confirmed that it is using AI tools to write code for Unreal Engine, Fortnite and related projects. Executive vice-president Marcus Wassmer says engineers guide and refine the AI-generated code, while Epic argues that adopting the tools helps it deliver features and keep pace with development.

The tools include Claude Code and Codex. Epic says they helped eliminate long-standing non-deterministic cooking bugs, speed up shader compression work and rewrite much of its D3D12 rendering layer in about a week, compared with an estimate of three to six weeks for one engineer. Wassmer says most current development is happening in projects linked to Fortnite, Unreal Editor for Fortnite and Unreal Engine 6.
