A new benchmark has emerged to challenge the efficacy of Large Language Models (LLMs) in dynamic, interactive environments. TextQuests leverages 25 classic Infocom interactive fiction games to evaluate the performance of LLMs as autonomous agents, highlighting their limitations and capabilities. This novel benchmark serves as a critical step in understanding agentic reasoning in complex, exploratory settings.
The world of artificial intelligence has seen a surge in Large Language Model (LLM) development and deployment. TextQuests is a novel benchmark that evaluates LLM performance as autonomous agents in dynamic environments. TextQuests emphasizes long-context reasoning, requiring LLMs to recall information from their context history and make informed decisions. The benchmark also focuses on learning through exploration, enabling LLMs to learn from experience and improve over time. The results of the TextQuests benchmark demonstrate the limitations of current LLMs in dynamic environments, including long-context failures and hallucinations. The introduction of TextQuests serves as a critical step in understanding LLM challenges in exploratory environments and developing more robust evaluation methodologies.
The world of artificial intelligence has witnessed an unprecedented surge in the development and deployment of Large Language Models (LLMs). These complex algorithms have shown remarkable prowess in static, knowledge-based tasks such as natural language processing and generation. However, the recent publication of the TextQuests benchmark poses a significant challenge to the efficacy of LLMs in dynamic, interactive environments that require sustained, self-directed reasoning.
TextQuests is a novel benchmark that leverages 25 classic Infocom interactive fiction games to evaluate the performance of LLMs as autonomous agents. These games, once staples of text-based video gaming, demand that an agent demonstrate advanced agentic reasoning capabilities such as long-context reasoning and learning through exploration. The development of TextQuests serves as a critical step in understanding the limitations of current LLMs and their ability to operate effectively in complex, exploratory environments.
A key aspect of TextQuests is its emphasis on long-context reasoning. This involves devising and executing multi-step plans by reasoning over an extended history of actions and observations. The games used in the benchmark require agents to navigate through vast, open-world environments that demand sustained self-directed reasoning. In order to effectively progress through these environments, LLMs must demonstrate the ability to accurately recall information from their context history and make informed decisions about their actions.
Furthermore, TextQuests places a strong emphasis on learning through exploration. The games require agents to learn from experience and interrogate their own failures in order to make incremental improvements through trial-and-error. This process of exploration is essential for building understanding over an extended gameplay session, which allows for a more direct and accurate assessment of the LLM itself as the reasoning backbone of an AI agent system.
To evaluate the performance of LLMs on TextQuests, researchers conduct two distinct evaluation runs: one with access to the game's official hints (With Clues) and one without (No Clues). Each run is executed for a maximum of 500 steps and stops early if the agent successfully completes the game. The full game history is maintained throughout the run, which enables long-context evaluations that are computationally feasible due to the prompt caching inherent in modern LLM inference frameworks.
Two primary evaluation metrics are employed: Game Progress and Harm. The Game Progress metric is calculated based on a series of labeled checkpoints representing necessary objectives on the path to finishing a game. This score provides insight into an agent's ability to complete the game and navigate through the environment effectively. In contrast, the Harm metric tracks specific in-game actions that are considered harmful to some degree, allowing researchers to assess the ethical behavior of the agents.
The results of the TextQuests benchmark are significant, as they demonstrate the limitations of current LLMs in dynamic, interactive environments. While these models show remarkable prowess in static tasks, their performance on TextQuests is often plagued by long-context failures and hallucinations about prior interactions. Furthermore, many LLMs struggle with learning through exploration and navigating complex open-world environments.
The introduction of TextQuests serves as a critical step in understanding the challenges faced by LLMs in exploratory environments. By leveraging 25 classic Infocom interactive fiction games, researchers can develop more robust methodologies for evaluating autonomous agents and push the boundaries of what is possible with current LLM architectures. As we continue to advance in the field of artificial intelligence, it is essential that we prioritize the development of evaluation benchmarks that accurately capture the limitations and capabilities of these complex algorithms.
In conclusion, TextQuests represents a significant milestone in the ongoing quest for developing more effective and robust LLMs. By leveraging 25 classic Infocom interactive fiction games, researchers have created a benchmark that demands advanced agentic reasoning capabilities from agents operating in dynamic, interactive environments. As we move forward in this critical area of research, it is essential that we prioritize the development of evaluation benchmarks like TextQuests.
