Research questionHow does reviewer capability relative to the executor affect rejection, repair, and accuracy in LLM execute-review-revise pipelines?A reviewer may identify genuine errors, reject correct answers, or fail to induce a useful repair. The capability gap between executor and reviewer can therefore change whether review improves or harms the pipeline’s final result.

Reviewers span capability tiers, including same-model, cross-family mid-tier, and weakest-reviewer conditions; measured outcomes include rejection, repair, final accuracy, false rejection, answer damage, and token cost. Findings are limited to this setup and should not be treated as a general claim about all verification pipelines.research paper · Sep 2, 2026
