Ce qui s'est passé: When Does Muon Help Agentic Reinforcement Learning?

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.

Pourquoi ça compte: When Does Muon Help Agentic Reinforcement Learning?

Matters for engineers optimizing language models for agentic RL tasks, especially when tuning learning rates and advantage estimators for policy training.

Vigilance: When Does Muon Help Agentic Reinforcement Learning?

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.
