    Cognition 用 Devin 智能体集群完成 RSA-260 分解

    Cognition 研究团队用 Devin 智能体集群完成 260 位数字 RSA-260 的分解,刷新公开求解的 RSA Factoring Challenge 纪录,此前纪录 RSA-250 于 2020 年 2 月创下。团队称 Devin 构建了性能最高的 GPU 格筛器,使分解成本比此前公开最优水平低 10 倍,本次分解约耗 4,900 GPU-days(约 13.5 GPU-years),按市场价约 40 万美元。作者估算,超大规模厂商或前沿 AI 实验室分解 RSA-1024 的成本约为每个 3000 万美元,而 RSA-2048 的难度约为 RSA-1024 的十亿倍,基本不受此工作影响。

    预训练进步主要来自数据而非模型改进

    Dwarkesh Patel 博客发布一项研究,把 2019 至 2025 年的预训练进步拆分为数据与模型两部分。在 1e19 FLOPs 算力预算下,数据改进带来 12.0x 的算力效率提升,模型改进为 3.7x,前者约为后者的 3.24x。研究还发现两者收益基本相互独立,88% 的 OLMES 评测分数方差可由模型与数据的加性效应解释。
