From Static to Dynamic: Benchmarking Real-World Code Review with MCR-Bench

The paper introduces MCR-Bench, a benchmark for realistic multi‑round code review that includes 2,269 real‑world tasks across five programming languages, each annotated with fine‑grained defect information and dynamic state labels. Experiments with mainstream large language models show limited overall performance, especially as interaction rounds increase, and reveal that model accuracy varies by defect type and severity. Error analysis identifies key failure mechanisms such as cross‑round temporal misalignment and insufficient long‑range memory.

More Criticism Does Not Make a Better Review: EquiReview-R

The paper introduces EquiReview‑R, an AI‑assisted review system that treats omission and over‑critique as distinct risks and refines a structured concern set using evidence‑linked reasoning. It demonstrates that more criticism does not guarantee a better review, showing that many high‑recall reviews lack definitive evidence for concerns and that revision before further search is essential. On a held‑out set of papers, EquiReview‑R meets non‑inferiority for major omission, cuts major over‑critique from 15.5 % to 8.1 %, and stops on 52.4 % of papers, with gains attributed to revision rather than extra inference.

FLAWS: A Benchmark for Error Identification and Localization in Scientific Papers

FLAWS is a new benchmark that tests large language models’ ability to find and pinpoint errors that invalidate key claims in scientific papers. The dataset contains 713 paper‑error pairs created by inserting claim‑invalidating mistakes into peer‑reviewed articles using LLMs, and it includes an automated metric for measuring error detection and localization. Five state‑of‑the‑art LLMs were evaluated, with GPT‑5 achieving the highest accuracy of 39.1% when selecting the top 10 candidate error texts.

Suppressed, Not Erased: A Representational Trace of Edited Facts Survives Even Weight-Free Knowledge Editing

The paper investigates whether knowledge editing truly erases original facts from language models. Using a linear trace probe, the authors find that after editing a fact in GPT‑2‑XL, the original object remains highly decodable from hidden states across three different editing methods, even when the model behaves correctly on edited prompts. This suggests that editing suppresses rather than removes the original association in representational space.
