Key Findings
Methodology
The study employs a self-playing adversarial language game, Adversarial Taboo, to enhance LLM reasoning through reinforcement learning. The attacker induces the defender to unconsciously speak the target word, while the defender tries to infer it. Experiments use LLaMA-2-7B and Baichuan-2-13B models with target words selected from a 50K high-frequency vocabulary.
Key Results
- SPAG improved LLaMA-2-7B's performance by 5% on reasoning benchmarks, showing significant gains on datasets like MMLU and BBH.
- Baichuan-2-13B saw a 3% reasoning improvement post-SPAG training, especially on the ARC-e dataset.
- Compared to non-adversarial games, adversarial games show superior reasoning enhancement.
Significance
This research demonstrates the potential of self-playing adversarial games to enhance LLM reasoning, overcoming the dependency on additional data and human annotation in traditional methods. It holds significant implications for both academia and industry by providing a new pathway for model capability enhancement.
Technical Contribution
Introduced a self-playing adversarial training framework that significantly enhances LLM reasoning without human intervention, combining reinforcement and imitation learning. The method automates game outcome judgment, reducing human involvement and increasing training efficiency.
Novelty
First to apply self-playing adversarial games to enhance LLM reasoning, breaking traditional method limitations and offering a new training approach without additional data.
Limitations
- In specific language tasks, models may overfit to game rules, reducing generalization ability.

Imagine playing a guessing game with a friend. One person knows a secret word, and the other has to guess it through conversation. This game is like training a large language model, which learns to understand and reason better through continuous dialogue and guessing. Just as you get smarter playing the game, the model improves its reasoning ability through this process.

Abstract
We explore the potential of self-play training for large language models (LLMs) in a two-player adversarial language game called Adversarial Taboo. In this game, an attacker and a defender communicate around a target word only visible to the attacker. The attacker aims to induce the defender to speak the target word unconsciously, while the defender tries to infer the target word from the attacker's utterances. To win the game, both players must have sufficient knowledge about the target word and high-level reasoning ability to infer and express in this information-reserved conversation. Hence, we are curious about whether LLMs' reasoning ability can be further enhanced by Self-Playing this Adversarial language Game (SPAG). With this goal, we select several open-source LLMs and let each act as the attacker and play with a copy of itself as the defender on an extensive range of target words. Through reinforcement learning on the game outcomes, we observe that the LLMs' performances uniformly improve on a broad range of reasoning benchmarks. Furthermore, iteratively adopting this self-play process can continuously promote LLMs' reasoning abilities. The code is available at https://github.com/Linear95/SPAG.
