Andrej Karpathy demonstrated the potential of large language models by tasking Claude Opus 5 with generating a 3D interpretation of the first paragraph of The Lord of the Rings. With a 1 million token budget, the model produced over 5,500 lines of code in approximately two hours, creating a playable 3D world. This experiment highlights a shift from simple Q&A to complex, autonomous agentic work, suggesting a future where LLMs can create bespoke, on-demand virtual environments at a low cost. However, Karpathy noted that current models lack native multimodal perception, hindering their ability to self-audit and refine complex visual outputs like games or 3D worlds. AI
