Bun, 11일 만에 100만 줄 코드 재작성 — 그 어느 때보다 빨라졌다
Anthropic의 Claude Fable 5가 11일 만에 Bun을 Zig에서 Rust로 재작성하며 100만 줄이 넘는 코드를 생성했습니다. 이는 개발자 생산성의 대대적인 전환을 시사합니다.
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.
