SweSmith-8B-SFT-NoRope-step58#

RL-trained Qwen3-8B on SWEsmith tasks (32k context, no rope scaling, 58 steps). Beats the SFT base model on dev_set_71 (pass@1 0.227 vs 0.213) and SWE-bench 100 (0.220 vs 0.210).

Training Details#

Base model: laion/r2egym-nl2bash-stack-bugsseq-fixthink-again (Qwen3-8B SFT)
Training method: RLOO-N (Reinforcement Learning with Leave-One-Out baselines)
Training data: 2,500 SWEsmith tasks (oracle-verified, 120s timeout)
Framework: BenSkyRL + Harbor
