## AI 摘要

一项对 207 个 GitHub 项目、102 万次拉取请求的研究发现，采用 AI 智能体审查的项目，每千行代码（KLOC）的审查时间缩短了 2.5 至 4.5 天。但早期大量使用 LLM 审查的项目未见显著效率提升。AI 审查模式在 78%-94% 的拉取请求中存在“审查异味”，高于人工审查的 69%-76%，主要原因是重复分配同一 AI 审查者身份导致多样性下降。

Agents can compress review time without improving the review process itself.

A study of 1.02 million pull requests across 207 GitHub projects tracks the shift from human-only review to LLM-assisted and agentic review. Projects that adopted AI gradually， or moved rapidly to agents， saw review time fall by 2.5 and 4.5 days per KLOC （the code change in thousands of lines of code） in the agent era.

Projects that adopted LLM reviewers heavily and early saw no significant efficiency gain.

The pull-request interaction patterns explain part of that split.

Agent-initiated and multi-agent reviews reached decisions faster than human-only review under gradual and rapid-agent adoption. Agents often performed the initial inspection and summary， leaving the human reviewer with a shorter exchange.

But most AI-involved patterns had review smells in 78% to 94% of pull requests， versus 69% to 76% for human-only review.

Much of the difference came from repeatedly assigning the same AI reviewer identity， which narrows reviewer diversity.
