LLM Zelda Level Generator Hits Diversity Metric but Produces Visually Boring Rooms

The author shares a paper on LLM-driven game level generation (PCG), co-authored with uTheProdigy, MatthewSiper, Steven James, and Togelius.
An honest limitation: high fitness ≠ visual diversity. Their Zelda generator learned to clear the room and shuffle key/door/player positions — scoring well on shortest-path diversity metrics while being boring to look at.
The proposed next step is quality-diversity (QD) search, to maintain genuinely diverse outputs while still optimizing objectives.
