  "title": "UnifiedPlayers: Enhance Tool-Integrated Reasoning in Agentic Reinforcement Learning",
  "summary": "UnifiedPlayers replaces static verifiers and self-consistency reward signals in self-evolving tool-integrated reasoning with three jointly trained players (task planner, trajectory executor, executable-verifier constructor) coordinated under GRPO. It costs a full reinforcement learning pipeline training three interacting model roles on model backbones, which exceeds a single 24 GB GPU budget and adds substantial engineering complexity around reward design and co-adaptation stability. It can fail through coordination instability, where each player's updates shift the data and feedback distribution of the others, and through verifier reward hacking if the evaluation player is exploited by the executor.",
  "rationale": "The method requires training multiple cooperating players with GRPO rather than an inference-time technique, so it demands training infrastructure and tuning effort that a constrained team cannot justify until distilled or lighter variants appear.",
