Theo宣布Rust版TypeScript编译器tsc-rs；pngwn称约1.6倍性能提升较为温和
Theo - t3.gg宣布tsc-rs（ts-rust），用Rust完整重写TypeScript编译器、类型检查器和LSP，由agent开发约5个月；他表示此前烧掉约40万美元Codex代币没有进展，约2万美元Opus则在两周内完成。pngwn表示LLM能做到这一点已令人惊讶，但约1.6倍的性能提升相对投入而言较为温和，仅比ts6高一个数量级，与ts7相同。

RT pngwn This is interesting both because it is impressive and also because it isn’t. Crazy that an LLM can even pull it off. But interesting that the performance jump is pretty modest, ~1.6x is pretty modest considering the effort. Only an order of magnitude over ts6 (same as ts7). Theo - t3.gg: Announcing tsc-rs (aka ts-rust), my complete rewrite of the Typescript compiler, type checker, and LSP, all in Rust. This is a project I've had agents working on for 5 months now. I burned ~$400k of Codex tokens and got nowhere. Burned ~$20k of Opus and got there in 2 weeks. I
