Bun 在 11 天内重写 100 万行代码 — 速度比以往任何时候都快
anthropic 的 claude fable 5 在 11 天内将 bun 从 zig 重写为 rust，生成了超过 100 万行代码。这标志着开发者生产力的巨大转变。
bun developer jarred sumner utilized a pre-release version of anthropic's claude fable 5 to completely rewrite the bun javascript runtime from zig to rust in just 11 days. running 64 instances in parallel, the ai generated over 1 million lines of code for an api cost of $165,000, a task estimated to take a human team a year. the new rust-based bun v1.4.0 canary build fixes 128 memory errors, runs 2-5% faster, and offers improved reliability. this acceleration highlights how advanced models are poised to fundamentally disrupt traditional software development workflows.
