The evaluation shows trajectory-level RL advantages depend on sufficient interaction depth, indicating that reported gains for LLM agents hinge on how many turns and samples the agent is allowed.", "body_md": "While multi-turn agentic reinforcement learning (RL) excels on long-horizon tasks, its performance gains remain highly sensitive to interaction constraints.
