Artificial intelligence got better at building itself

摘要

本文探讨了 AI“递归自我改进”的实际进展。以 Anthropic 为例，自 2025 年发布 Claude Code 软件工程代理工具后，该公司内部代码产出中由 AI 编写的比例从个位数激增至 80% 以上。这种 AI 构建 AI 的模式正成为行业趋势，并为其即将到来的 IPO 提供了技术支撑。

荐读理由

Anthropic 内部代码由 AI 生成的比例在一年内从个位数飙升至 80% 以上，这一量化事实为你判断 AI 编程 Agent 在重度工程环境下的替代上限与落地深度提供了关键的决策依据。
