Muon optimizer shows promise in agentic reinforcement learning tasks

A new research paper explores the effectiveness of the Muon optimizer in agentic reinforcement learning (RL) tasks, particularly when applied to sparse-reward environments. The study, using Qwen2.5-0.5B-Instruct on the ALFWorld benchmark, found that incorporating Muon into hidden weight matrices significantly improved success rates compared to the standard AdamW optimizer. The benefits of Muon were observed to be dependent on factors such as the advantage estimator and learning rate, with specific configurations leading to substantial gains in validation success and faster convergence.
