TL;DR
A team has created a $99 proof of concept using a text-based Multi-User Dungeon (MUD) to evaluate large language models (LLMs). This approach aims to provide a low-cost alternative for assessing AI performance, sparking interest in unconventional evaluation methods.
Researchers have developed a $99 proof of concept that uses a classic text-based Multi-User Dungeon (MUD) to evaluate large language models (LLMs). This approach aims to provide a low-cost, accessible alternative to traditional AI evaluation methods, which often require extensive resources and specialized setups. The project was shared by the authors in early 2024, sparking discussions about novel assessment techniques for AI systems.
The team, composed of AI researchers and enthusiasts, spent several months exploring whether a MUD—a genre of text-based multiplayer games originating in the 1970s—could serve as an evaluation platform for LLMs. They built a minimal setup costing approximately $99, integrating the LLMs into the game’s environment to perform tasks, answer questions, and interact with game elements. The core idea is that the complexity and interactivity of a MUD can serve as a proxy for evaluating AI capabilities in understanding, reasoning, and adapting to dynamic scenarios.
According to the authors, initial tests showed that the MUD-based evaluation could differentiate between models of varying sizes and training levels. They argue this method could democratize AI evaluation by reducing costs and hardware requirements, making assessments more accessible to smaller labs and independent researchers. The proof of concept is currently in early stages, with ongoing experiments to refine the approach and validate its effectiveness compared to standard benchmarks.
Potential Impact of a Low-Cost Evaluation Method
This development could significantly lower the barriers to evaluating large language models, enabling broader participation in AI research and development. Traditional evaluation methods often involve expensive hardware, proprietary datasets, and extensive computational resources. A MUD-based approach offers a lightweight, flexible alternative that can be deployed with minimal costs, potentially accelerating innovation and testing in the field. However, it remains uncertain how well this method correlates with established benchmarks and whether it can replace or complement existing evaluation standards.

Background on AI Evaluation Challenges and MUDs
Evaluating large language models typically involves standardized benchmarks like GLUE, SuperGLUE, or custom datasets that measure accuracy, reasoning, and language understanding. These assessments often require significant compute resources and access to proprietary data. In contrast, MUDs are text-based multiplayer games that simulate interactive environments, historically used for entertainment and social interaction since the 1970s. Recent interest has emerged in repurposing such environments for AI testing, leveraging their complexity and interactivity as proxy evaluation environments. The idea of using a MUD for AI evaluation is novel and still experimental, with this proof of concept representing one of the earliest formal attempts.

Limitations and Validation of the MUD Evaluation Method
It is not yet clear how well the MUD-based evaluation correlates with traditional benchmarks or real-world performance. The approach is still in early testing phases, and further validation is needed to establish its reliability and scope. Additionally, questions remain about how adaptable the method is across different types of LLMs and tasks, and whether it can be standardized for broader use.

Next Steps for Developing MUD-Based AI Evaluation
The researchers plan to expand their experiments, comparing MUD-based assessments with conventional benchmarks across multiple models. They aim to refine the environment, automate scoring mechanisms, and conduct larger-scale testing to evaluate consistency and validity. If successful, this could lead to broader adoption and further research into interactive environments as evaluation tools for AI systems.
