    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。

Exciting work beckons anywhere programming can be used to solve a research problem; I encourage all to be ambitious and explore what autonomous software engineering agents can do when applied to these fields!
