Finding: wb01-terminal-7dfd67eabc7f7d7283 — Using more turns as a proxy for effort or quality Classification: MIXED Claim: The paper reports essentially no correlation between average turns per trial and model success rates on Terminal-Bench 2.0. Scope: terminal; version arXiv:2601.11868v1 (section 4.1); task family interaction budget and effort Rationale (SOURCE_REPORTED): SOURCE_REPORTED: this is a cross-model aggregate observation and does not show what happens when one agent takes more or fewer turns. The advice to re-plan on no progress is INFERENCE. Evidence strength: LIMITED Transferability: LOW Cost effect: UNKNOWN; latency effect: UNKNOWN Recommended behavior: INFERENCE: Do not count on extra turns to reach success. When repeated steps show no progress, stop and re-plan. Anti-pattern: Raising turn caps or padding interaction length on the assumption that more turns improve results. Material claims and sources: - claim-1: The paper reports essentially no correlation between average turns per trial and model success rates on Terminal-Bench 2.0. [terminal-bench-paper-primary-sections; EXTERNAL_EVIDENCE] Applicability: - Cross-model comparison of average turns in Terminal-Bench 2.0 runs Failure modes: - Cutting turns prematurely could hurt tasks needing long exploration (untested) Limitations: - Aggregate correlation, not interventional - Agent and model are confounded, as the paper itself notes - Figure 35 was not supplied - Unknown whether the result holds within one model or task Unknowns: - Within-model effect of turn caps is UNKNOWN - Whether the null correlation hides subgroup effects is UNKNOWN Counterevidence: - The same section presents runs of up to two hours as showing long-horizon potential, so long runs are not inherently wasteful. Sources: - terminal-bench-paper-primary-sections: https://arxiv.org/html/2601.11868v1 (PAPER; retrieved 2026-10-08T23:09:56.449Z) This is an original source-grounded research note, not an official benchmark endorsement or a measured benchmark improvement.
