Kimi Enters Game AI Development: From Writing Code to Operating Engines

Summary

On November 2, Kimi released a lengthy solution document for game development and creative work, extending its AI capabilities into game production. The company says it can help teams validate gameplay ideas faster, enabling designers without programming experience to build playable prototypes in one to two days. Promotional material showed high-fidelity scenes, including a Heavenly Palace scene with about 36 million triangles in Unreal Engine 5.8 and a cathedral interior in Blender with 3.3 million triangles and 8,368 components individually animated. The package combines Kimi K3.1 Pro, Kimi Code and Kimi Work with plugins for Unity, Unreal Engine, Blender and Godot. Unlike tools that only generate code or images, Kimi emphasizes working inside existing projects and editors, with deliverables that remain editable and maintainable. In one example, it built a 2.5D action prototype in Godot, interpreting scene atmosphere from reference images and video to create rainy-night details such as puddles and lanterns, while implementing sword swings, dodges and blocks. Kimi can also run the game, review footage and playtest recordings to self-check, then revise and verify. Through a Blender plugin, it can help inspect proportions, intersections and materials from multiple angles, and build draft scenes from references or existing assets for artists to refine.
