ReTerm-9B

This repository contains ReTerm-9B, presented in ReTerm: Recovery Training for Self-Improving Terminal Agents. ReTerm-9B is a self-improving terminal agent built on Qwen3.5-9B through SFT and ReTerm-GRPO. The model uses the Qwen3.5 architecture and chat template.

👀 About ReTerm

We introduce ReTerm, a self-improving terminal agent trained to recover from errors produced during its own execution.

We construct ReTerm-10K, a high-quality recovery trajectory dataset generated through a dedicated data pipeline for SFT cold start. Moreover, we propose ReTerm-GRPO, an online RL algorithm that branches into multiple independent self-recovery attempts from the agent's own failure states. Their verifier outcomes provide group-relative learning signals, enabling the agent to self-improve through its own recovery experience.

Built on Qwen3.5-9B, ReTerm-9B demonstrates strong performance on challenging terminal and software engineering tasks, with generalization across out-of-domain benchmarks and different agent harnesses.

🏆 Performance

ReTerm-9B achieves strong results on terminal and software engineering benchmarks:

Benchmark	Pass@1
OpenThoughts-TBLite	60.6%
Terminal-Bench 2.0	34.8%
SWE-bench Verified	58.4%
AIME 2024	86.7%
AIME 2025	93.3%
Aider Polyglot	20.4%
SpreadsheetBench Verified	48.8%

Beyond these core evaluations, ReTerm also generalizes to out-of-domain tasks, including mathematical reasoning and spreadsheet processing. The improvement trend persists across different agent harnesses, suggesting transferable capabilities across interaction setups.

🔧 Using the model

ReTerm-9B can be loaded with Qwen3.5-compatible inference frameworks. For terminal-agent use, apply the Qwen3.5 chat template and tool-call protocol with an agent harness that executes commands and returns environment observations. Training code and configurations are available in the ReTerm repository.
