何が起きたか: Researchers tested Muon optimizer on reinforcement learning post-training for language models, finding it outperforms AdamW in sparse-reward agent tasks with proper hyperparameter tuning.
なぜ重要か: Matters for engineers optimizing language models for agentic RL tasks, especially when tuning learning rates and advantage estimators for policy training.
注意点: Results are single-seed experiments on one task and model size. Multi-seed validation and cross-task generalization remain unverified, limiting confidence in broad applicability.
