rl_r2egym-nl2bash-swesmith-pymethods2test_terminus-structured#

RL-trained Qwen3-8B with structured tool calls.

Training pipeline: SFT (r2egym+nl2bash+swesmith) → RL mixed dataset (37 steps) → RL full r2egym (55 steps) → RL pymethods2test (110 steps).

Key results:

  • SWEBench-100: 42% pass@3 (vs 37% base with terminus-2)
  • Pymethods2test: 94-100% pass@8
  • 14 SWEBench tasks solved that base model cannot
  • Trained with terminus-structured agent (bash, view, edit, create, search tools)

Training Details#

  • Base model: laion/r2egym-nl2bash-stack-bugsseq-fixthink-again
  • Training method: rloo-n with terminus-structured agent (structured tool calls: bash, view, edit, create, search)
  • Framework: BenSkyRL + Harbor
  • Context: 32k (24k input + 8k output)
  • Learning rate: 1e-5
