Six October arXiv papers advance agent RL: GPPO, STEPGATE, SAG, LiRA, MoSDOT, CASTLE
New preprints unify PPO via f-divergence, add uncertainty-aware step-level handoff for SLMs, introduce gated critique for long-horizon agents, learn responsibility allocation in multi-agent constraints, preserve coordination modes in distillation, and equip decentralized agents with counterfactual world models.
