r/ArtificialInteligence: Independent Study — Single LLM Misses ~Half of Code-Review Defects That a Multi-Model Panel Catches, Seeking arXiv Endorsement

An independent researcher posted preliminary findings on June 3 measuring whether a single LLM is sufficient for automated code review, concluding that a solo model misses roughly half the defects caught by a panel of diverse models. The paper, the researcher's first, is seeking arXiv endorsement and has not yet been peer-reviewed; the post invites community scrutiny of methodology. If replicated, the finding has direct implications for teams using single-model code-review pipelines as a quality gate.
