A researcher created a $99 proof of concept using classic text-based MUD games to evaluate large language models. The development suggests low-cost, alternative methods for AI evaluation are possible, but many details remain uncertain.
A researcher has developed a $99 proof of concept that uses text-based MUD (Multi-User Dungeon) games to evaluate large language models (LLMs). This approach questions the necessity of expensive, complex evaluation frameworks and suggests a possible low-cost alternative. The project, still in early stages, aims to explore whether classic text games can serve as effective benchmarks for AI capabilities.
The researcher, who authored a recent paper on this topic, spent several months experimenting with MUD environments as a testing ground for LLMs. The proof of concept involves running LLMs through a MUD interface, where their ability to understand, respond, and navigate is assessed based on predefined tasks and interactions. The entire setup was built with a budget of approximately $99, primarily covering hosting and basic development tools.
According to the researcher, initial results show that LLMs can be evaluated based on their performance in these text-based environments, which simulate complex, interactive scenarios. The approach leverages the simplicity and accessibility of MUDs, which have been around since the 1970s, to create a scalable, low-cost testing framework. The researcher emphasizes that this is a proof of concept and not yet a comprehensive evaluation method.
Potential Impact of Low-Cost AI Evaluation Methods
This development is significant because it challenges the prevailing notion that evaluating large language models requires expensive, resource-intensive benchmarks. If MUD-based testing proves effective, it could democratize AI evaluation, making it accessible to smaller labs and individual researchers. It also raises questions about the adequacy of current benchmarks, which often focus on specific tasks rather than general interactive capabilities. The approach could lead to more diverse and flexible assessment tools for AI performance, potentially accelerating innovation and understanding in the field.

Background on AI Evaluation and MUD Environments
Traditional methods for evaluating large language models involve complex benchmarks, such as standardized tests, question-answering datasets, and performance metrics that often require significant computational resources. These methods can be costly and may not fully capture a model’s ability to interact in dynamic, real-world scenarios.
Meanwhile, MUDs are text-based multiplayer games originating in the 1970s, designed for interactive storytelling and exploration. While historically used for entertainment, their structure—rich in language, problem-solving, and interaction—makes them an intriguing candidate for AI testing. Prior research has explored using game environments for AI training, but using them as evaluation tools remains relatively unexplored.
The recent proof of concept builds on this background, aiming to see if such environments can serve as a low-cost, flexible alternative to traditional benchmarks.
“Using classic MUD environments, we can assess LLMs’ understanding and interaction skills at a fraction of the cost of conventional benchmarks.”

Limitations and Validation Challenges of MUD-Based Evaluation
It is not yet clear how well MUD environments can measure the full range of LLM capabilities, such as reasoning, creativity, or long-term consistency. The current results are preliminary, and the evaluation framework has not been widely tested across different models or tasks. Additionally, questions remain about how to standardize assessments and compare results across different implementations. The researcher acknowledges that more rigorous testing and validation are needed before this approach can be considered a reliable evaluation method.
Next Steps for MUD-Based AI Evaluation Development
The researcher plans to expand testing to include more complex MUD scenarios and different LLM architectures. Future work will focus on developing standardized metrics, conducting comparative studies with existing benchmarks, and publishing detailed results. Collaborations with other AI researchers and institutions are also anticipated to validate and refine this approach. The goal is to establish whether MUD environments can become a practical, scalable tool for AI evaluation in the near future.
Key Questions
Can a MUD effectively evaluate all aspects of an LLM?
Currently, it is uncertain whether MUDs can assess all capabilities of large language models, such as reasoning or creativity. The proof of concept primarily tests interaction and understanding within text-based environments.
How much did the project cost to develop?
The entire setup was developed for approximately $99, covering hosting, basic tools, and minimal development expenses.
Is this approach ready to replace traditional benchmarks?
No, this is an early-stage proof of concept. Further testing and validation are required before it can be considered a reliable alternative.
What advantages do MUD environments offer for AI evaluation?
They are low-cost, accessible, and capable of simulating complex, interactive scenarios that may better reflect real-world AI capabilities.
