LLM code repairs can be silently wrong, study finds

A new study published on arXiv reveals that Large Language Models (LLMs) can generate code repairs that appear correct but are functionally wrong, a problem exacerbated by API migrations. Researchers found that standard testing methods often fail to catch these silent errors. While specific input strategies and a blind AI audit improved detection rates, a significant portion of incorrect code still passed. AI

IMPACT Highlights the need for more robust testing and validation methods for LLM-generated code, especially in production environments.

    Accepted but Wrong: Silent Failures of LLM Code Repairs after API Migrations

    arXiv:2611.08269v1 Announce Type: cross Abstract: After a runtime or API migration, an LLM-repaired procedure can run cleanly yet return wrong results, and a release check on typical test inputs ships it. We report a preregistered study of 73 tasks covering 60 documented changes …
