LLM Learns to Play With Itself (and Gets Better?!)
This paper proposes Language Self-Play (LSP), a technique where a large language model (LLM) improves by generating its own training data through self-play in a competitive game. Experiments on instruction-following tasks showed LSP improved performance without external data, sometimes even exceeding models trained on real data.
Possible Conflicts of Interest
The authors are affiliated with Meta Superintelligence Labs, which may have a vested interest in the development of LLMs.
Identified Weaknesses
The evaluation is limited to instruction-following tasks on the AlpacaEval benchmark. The generalizability of LSP to other tasks and domains remains unclear.
Potential for Adversarial Nonsense
The self-play process can sometimes degenerate into generating nonsensical or adversarial queries, hindering learning. The paper uses self-rewards to mitigate this, but it may not be foolproof.
Dependence on Reward Model
The effectiveness of LSP hinges on the quality of the reward model used. A poor reward model could lead to suboptimal learning or undesirable behaviors.
Rating Explanation
Novel approach to LLM training with promising results on a specific benchmark. However, limited evaluation and potential pitfalls prevent a higher rating.
