The blog post details the author's successful attempt at getting OpenAI's language model, specifically GPT-3 (codenamed "o1"), to play the board game Codenames. The author found the AI remarkably adept at the game, demonstrating a strong grasp of word association, nuance, and even the ability to provide clues with appropriate "sneekiness" to mislead the opposing team. Through careful prompt engineering and a structured representation of the game state, the AI was able to both give and interpret clues effectively, leading the author to declare it a "super good" Codenames player. The author expresses excitement about the potential for AI in board games and the surprising level of strategic thinking exhibited by the language model.
Suveen Ellawal's blog post details their fascinating experiment using OpenAI's large language model, specifically the GPT-3 variant they identify as "o1", to play the popular board game Codenames. Ellawal meticulously describes the process of adapting the game for a text-based interface suitable for interaction with the AI. This involved representing the game board as a grid of words, clarifying the roles of the spymaster and the guesser, and establishing a clear communication protocol for giving and interpreting clues.
The core of the experiment was to test the AI's ability to perform both roles: generating effective one-word clues as the spymaster, and correctly guessing the target words as a guesser. Ellawal provides extensive examples of the AI's gameplay, showcasing its surprisingly adept performance. The AI demonstrated a capacity to understand not just the meanings of individual words but also the subtle relationships between them, allowing it to generate clues that connected multiple target words while avoiding association with the opposing team's words or the assassin word. Furthermore, the AI exhibited an understanding of the game's mechanics, such as the risk of guessing too many words based on a single clue.
Ellawal notes specific instances where the AI impressed them, such as generating clever and unexpected clues, accurately interpreting ambiguous clues, and strategically navigating the board to maximize points. The post also highlights some of the AI's limitations, including occasional misinterpretations of words and a tendency to generate clues that were technically valid but perhaps too abstract or complex for a human player to easily decipher. Despite these limitations, the overall assessment is that the AI exhibited a remarkably strong grasp of Codenames, suggesting a significant advancement in natural language processing and game-playing capabilities.
The author concludes by reflecting on the broader implications of this experiment, speculating on the potential for AI to excel in other complex games and tasks requiring nuanced understanding of language and strategy. They also express excitement about future developments in AI and the potential for even more sophisticated gameplay. Ellawal provides the entire interaction log as supplementary material, allowing readers to delve into the specifics of each turn and further appreciate the AI's performance.

HN users generally agreed that the demo was impressive, showcasing the model's ability to grasp complex word associations and game mechanics. Some expressed skepticism about whether the AI truly "understood" the game or was simply statistically correlating words, while others praised the author's clever prompting. Several commenters discussed the potential for future AI development in gaming, including personalized difficulty levels and even entirely AI-generated games. One compelling comment highlighted the significant progress in natural language processing, contrasting this demo with previous attempts at AI playing Codenames. Another questioned the fairness of judging the AI based on a single, potentially cherry-picked example, suggesting more rigorous testing is needed. There was also discussion about the ethics of using large language models for entertainment, given their environmental impact and potential societal consequences.
The Hacker News post discussing the author's experience getting OpenAI's models to play Codenames has generated a moderate number of comments, mostly focusing on the intricacies of prompting and the surprising effectiveness of large language models (LLMs) in complex games.
Several commenters delve into the specifics of the prompting techniques used. One commenter questions how the model handles the asymmetric information inherent in the game, specifically how the "spymaster" clues are conveyed and interpreted by the "guessers" (which are also instances of the LLM). They propose a more explicit prompt structure to ensure the model understands the roles and limitations of information access within the game. Another commenter highlights the importance of prompt engineering in eliciting the desired behavior from the LLM, suggesting that even slight modifications to the prompt can significantly impact the model's performance. This discussion underscores the crucial role of carefully crafted prompts in guiding LLMs towards successful outcomes in complex tasks.
Another thread explores the surprising capabilities of LLMs in understanding nuanced concepts like those present in Codenames. One commenter expresses astonishment at the model's ability to grasp the game's mechanics and generate relevant clues, even though it hasn't been explicitly trained on Codenames. This observation sparks a discussion about the emergent abilities of LLMs, suggesting that their vast training data allows them to adapt to novel situations and tasks without specific training.
Some commenters share their own experiences with using LLMs for similar game-playing scenarios. One relates an anecdote about using GPT-3 to play a collaborative storytelling game, highlighting the model's ability to maintain character consistency and contribute creatively to the narrative. This adds another dimension to the conversation, demonstrating the versatility of LLMs in different gaming contexts.
A few commenters express skepticism about the claims of the original post, questioning the methodology and the robustness of the results. They suggest that the apparent success of the LLM might be due to limited testing or cherry-picked examples. This critical perspective adds balance to the discussion, emphasizing the need for rigorous evaluation and further experimentation to validate the findings.
Finally, some commenters discuss the implications of LLMs for game design and the future of AI. They speculate about the potential of LLMs to create dynamic and engaging game experiences, potentially leading to a new era of AI-driven interactive entertainment.
Overall, the comments on the Hacker News post reflect a mixture of excitement, curiosity, and healthy skepticism about the potential of LLMs in complex game playing. The discussion delves into the technical details of prompting, explores the emergent capabilities of these models, and considers the broader implications for the future of gaming and AI.
