AdvRole: adversarial closed-loop curriculum for RL role-playing agents
An arXiv paper (arXiv:2609.28609v1) introduces AdvRole, an adversarial context‑rewriting framework that alternates between an Actor (learning to role‑play) and a Rewriter (editing character profiles and dialogue contexts) to create a closed‑loop curriculum; the Rewriter is trained with a performance‑gap reward so scenarios evolve to target the Actor's weaknesses. The authors report consistent improvements over baselines on three English/Chinese benchmarks and release a new multilingual benchmark.
