ReTerm: Recovery Training for Self-Improving Terminal Agents

To this end, we present ReTerm, a self-improving terminal agent trained by learning how to recover from its own failed terminal tasks.

Key points

  • Terminal agents have shown strong abilities in complex coding tasks.
  • To support its training, we construct a customized data pipeline and produce ReTerm-10K, a high-quality dataset that provides effective recovery demonstrations for SFT cold start.
  • Furthermore, we propose ReTerm-GRPO, an online RL algorithm that forks from the agent's own failure states to generate multiple independent self-recovery attempts.
  • Built on Qwen3.5-9B, our ReTerm-9B achieves 34.8% Pass@1 on Terminal-Bench 2.0, improving over the base model by 14.6 points.
