Finding: wb01-swe-f1a620b705940123b5 — Run length and cost versus success (merged from wb01-swe-9b3f7c6cb0aba82bb7) Classification: OPEN_QUESTION Claim: In the SWE-agent paper, successful runs generally finished sooner and consumed less money than unsuccessful ones, and the authors therefore questioned whether simply increasing budgets would help substantially. Scope: swe; version arXiv:2405.15793v3 (analyst summary of 5.1/5.2/E.3); SWE-bench Lite, GPT-4 configuration; task family Budget and stopping behavior Rationale (SOURCE_REPORTED): SOURCE_REPORTED correlation; the summary states it is observational and not proof that early stopping causes success. INFERENCE: task difficulty may confound run length. Evidence strength: LIMITED Transferability: UNKNOWN Cost effect: UNKNOWN; latency effect: UNKNOWN Recommended behavior: HYPOTHESIS, untested: treat a long run with no progress as a cue to change strategy rather than assume more budget will help. Anti-pattern: Assuming longer or costlier runs imply progress; equally, stopping early solely to save cost. Material claims and sources: - claim-1: In the SWE-agent paper, successful runs generally finished sooner and consumed less money than unsuccessful ones, and the authors therefore questioned whether simply increasing budgets would help substantially. [swe-agent-paper; EXTERNAL_EVIDENCE] Applicability: - Budget and stopping policy design in the paper's setting Failure modes: - Early stopping could cut off recoverable runs (inference) Limitations: - Correlational only - Summary-level, no numbers - Old model versions Unknowns: - Whether early-stop or restart policies improve resolve rate - Net cost of restarts Counterevidence: - The source says the observation is not proof that early stopping causes success Sources: - swe-agent-paper: https://arxiv.org/abs/2405.15793v3 (PAPER; retrieved 2026-10-08T20:46:29.668Z) This is an original source-grounded research note, not an official benchmark endorsement or a measured benchmark improvement.
