TL;DR
Researchers have developed a $99 proof of concept using text-based MUD games to evaluate large language models. This approach offers a low-cost, accessible alternative to traditional AI testing methods, though its effectiveness remains under investigation.
Researchers have introduced a $99 proof of concept that uses text-based Multi-User Dungeon (MUD) games to evaluate large language models (LLMs). This approach aims to provide an accessible, low-cost alternative to traditional AI testing methods, which often require expensive infrastructure or proprietary tools.
The project was led by an independent researcher and his team, who spent several months developing the concept. They used classic MUDs—text-based multiplayer games originating in the 1970s—as a testing environment for LLMs. The core idea is that these games, which require complex language understanding and decision-making, can serve as a benchmark for AI performance.
The team built a prototype costing approximately $99, leveraging open-source MUD platforms and publicly available LLMs. They tested the models’ ability to interpret game prompts, make decisions, and respond coherently within the MUD environment. The results, while preliminary, suggest that such low-cost setups could complement existing evaluation frameworks.
While the proof of concept demonstrates technical feasibility, the researchers emphasize that it is an initial step and not a definitive assessment tool. They note that further validation and comparison against standard benchmarks are needed to determine its reliability and scope.
Implications of Low-Cost AI Evaluation Using MUDs
This development is significant because it introduces a cost-effective, accessible method for evaluating large language models. Traditional benchmarks often involve expensive hardware, proprietary datasets, or complex setups, which can limit testing to well-funded labs or organizations.
By contrast, using classic MUD text games—widely available and simple to deploy—could democratize AI evaluation, enabling smaller teams and individual researchers to assess model capabilities without significant investment. This could accelerate innovation and transparency in AI development, especially for open-source models.
However, the approach’s effectiveness and accuracy in measuring model performance remain to be fully validated. If proven reliable, it could complement existing benchmarks, offering a quick, engaging way to gauge language understanding and decision-making.

Background on MUDs and AI Evaluation Challenges
Multi-User Dungeon (MUD) games are text-based multiplayer environments that originated in the 1970s and have long served as a platform for interactive storytelling and social interaction. Recently, researchers have explored their potential beyond entertainment, considering them as testing grounds for AI language understanding.
Traditional evaluation of large language models relies on standardized benchmarks like GLUE, SuperGLUE, or custom datasets, which can be costly and resource-intensive. There is growing interest in alternative, more accessible methods that can be deployed easily and at scale.
This project builds on the idea that MUDs, with their complex language interactions and decision-making requirements, could serve as practical environments for AI testing, especially if they can be implemented cheaply and efficiently.
“Using classic MUDs as evaluation environments could democratize AI testing, making it accessible to a broader community.”

Next Steps for Validating and Expanding MUD AI Evaluation
The researchers plan to conduct more extensive testing, comparing their MUD-based assessments with traditional benchmarks to evaluate accuracy. They also intend to explore different types of MUD environments and expand the approach to larger models. Further peer review and community feedback will be critical to determine whether this low-cost method can be adopted broadly.
