## Key points

- Epic says AI is writing much of Unreal Engine 6’s code.
- Engineers will guide and refine AI-generated features.
- The move has prompted concerns among developers.

## Summary

Epic has confirmed that it is using AI to write much of the code for Unreal Engine 6 and future Fortnite updates. Executive vice-president of development Marcus Wassmer said engineers guide AI tools and refine their output, while Epic sees the risk of adopting AI too slowly as greater than the risk of scepticism.

Wassmer said Epic is iterating with AI rather than generating the engine in one go, with engineers responsible for keeping it within memory, performance and scalability limits. The approach marks a change from a year ago, when chief executive Tim Sweeney denied AI was being used for Unreal Engine updates. The article notes developer concerns about understanding AI-written code, as well as reports of problems with Epic’s AI-coded launcher and a shift towards AI-first development on an unannounced crossover game.
