Researchers have developed CrucibleBench, a novel method for evaluating large language models (LLMs) by placing them within a text-based Multi-User Dungeon (MUD) environment. This approach leverages the inherent constraints of MUDs, such as limited actions, explicit social feedback from non-player characters (NPCs), and persistent world states, to measure LLM behavior in scenarios requiring trust, information gathering, and adaptation. The study found that using an LLM judge for evaluation can significantly alter model rankings, highlighting the instability of such methods and suggesting the need for greater transparency in reporting agreement and stability under judge ablation.
