swyx 转述称 Anthropic 用 Claude 将 Messages API 后端重写为 Rust，团队没有 Rust 开发者，由人类写计划并用真实流量比对新旧版本，CPU 下降 40-50%。该说法来自 @katelyn_lesse 在 @latentspacepod 的访谈，swyx 认为“永远不要做大重写”的建议已经过时。

its true, Anthropic really vibecoded their entire backend to Rust and none of you noticed
Anthropic rewrote its Messages API in Rust. Zero Rust devs on the team. Claude wrote the code. Humans wrote the plan and checked old vs new matched on real traffic. CPU dropped 40-50%. Pretty sure "never do the big rewrite" is dead advice. @katelyn_lesse on @latentspacepod在 X 查看被引用的帖子
