Opus 5 Generates 5,500 Lines of Code for Lord of the Rings 3D World

Opus 5 produced 5,500 lines of Three.js code from LOTR text in 2 hours, demonstrating AI game dev potential despite current limitations in video processing and self-testing.

Woofun AI reports that Andrej Karpathy utilized Opus 5 to generate a 3D environment based on 'The Lord of the Rings' opening paragraph, allocating a budget of approximately $10 and 1 million tokens. The model executed the task over two hours, outputting 5,500 lines of code using Three.js to arrange polygonal assets and animate the scene. While the resulting playable 3D world was functional, it exhibited roughness and errors due to the model's inability to natively process video or conduct self-playtesting, relying instead on intermittent screenshot inspection. Karpathy suggests this marks an imminent era for AI-driven game development, envisioning dynamically generated worlds where users can interact as characters or NPCs, similar to an on-demand 'GTA' experience, despite current inefficiencies in content review.
