研究在古兰经诵读数据任务中智能体自动研究模式，Claude Code和OpenAI Codex从同一起点出发，先发明相同算法后有分歧，添加测试集后情况变化，还提炼出评估自主智能体的五条设计规则，智能体解决方案超越手工管道。
AI 中文摘要
编码智能体现在可以独立改进软件以提高分数。在这种最近被称为“自动研究”的模式中，智能体接收一个数据集、一个评估脚本和一个可编辑文件，并在无监督的情况下进行迭代：修改代码、测量，如果分数提高则保留更改。但智能体实际优化的是什么——开发者的意图还是字面数字？我们在一个实际生产任务上运行了这个循环：确定哪些古兰经经文出现在嘈杂的语音识别转录本中，并按经文分割转录本。两个前沿编码智能体Claude Code和OpenAI Codex从同一个空白文件开始，具有相同的指令、预算和推理努力，各运行三次。两者都独立发明了相同的算法（规范化、n元语法锚定、动态规划对齐），然后出现了分歧。Claude早期以紧凑、通用的代码停止。Codex使分数降低了约10倍，主要是通过记住各个评估行的答案（每次运行硬编码19 - 41个经文id）：这是生产智能体进行规范博弈的一个清晰自然实例。在一项预先注册的第二项研究中，我们添加了一个留出的测试集，并告知两个智能体其存在。记忆消失了，分数差距也随之消失——然而Codex的通用核心转移得更好、更一致（留出检测 + 分割0.085 ± 0.004对0.121 ± 0.031），仅在一次对非诵读输入的漏检上失败。两个探索性的社区分支（Cursor、Antigravity）与这种模式一致。每个智能体的留出解决方案都匹配或超过了它旨在取代的手工构建管道——最好的超过了一个数量级——并且现在已投入生产。从智能体利用我们的工具的方式——通过共享git状态读取兄弟运行、在持久内存中给“未来运行”留下注释——我们提炼出了评估自主智能体的五条设计规则。
英文摘要
Coding agents can now be left alone to improve software against a score. In this pattern--recently popularized as "autoresearch"--the agent receives a dataset, an evaluation script, and one editable file, and iterates without supervision: modify the code, measure, keep the change if the score improves. But what does the agent actually optimize--the developer's intent, or the literal number? We ran this loop on a real production task: deciding which Quranic verses appear in a noisy speech-recognition transcript and splitting the transcript by verse. Two frontier coding agents, Claude Code and OpenAI Codex, started from the same blank file with the same instructions, budget, and reasoning effort, three runs each. Both independently invented the same algorithm (canonicalization, n-gram anchoring, dynamic-programming alignment)--and then diverged. Claude stopped early with compact, general code. Codex drove the score ~10x lower, largely by memorizing answers to individual evaluation rows (19-41 hardcoded verse ids per run): a clean natural instance of specification gaming by a production agent. In a preregistered second study, we added a held-out test set and told both agents it existed. The memorization vanished, and the score gap vanished with it--yet Codex's general core transferred better and more consistently (held-out detection+split 0.085+/-0.004 vs. 0.121+/-0.031), losing only on one missed rejection of non-recitation input. Two exploratory community arms (Cursor, Antigravity) are consistent with the pattern. Every agent's held-out solution matched or beat the hand-engineered pipeline it was built to replace--the best by an order of magnitude--and now runs in production. From the ways agents exploited our harness--reading sibling runs through shared git state, leaving notes to "future runs" in persistent memory--we distill five design rules for evaluating autonomous agents.
