Cross-Model LLM Code Review: Should you use Claude to review Codex or vice versa
Computer Science > Software Engineering arXiv:2607.21656 (cs) [Submitted on 22 Jul 2026] Title:Cross-Model LLM Code Review: Should you use Claude to review Codex or vice versa? However, it is not clear whether the pairing is worth its cost and time, or whether the order of the pairing matters. We run a controlled experiment on 116 recent hard and medium lcb tasks with Claude and Codex across six conditions to approximate a software practitioner's workflow: both solo baselines, both cross-model orderings, and both same-model orderings.
