+## Build toolchain

+These options update the TypeScript SDK build toolchain to use faster, modern build tools. Enabling both options can speed up generation time by up to 35% in GitHub Actions and locally.

+<Callout title="Generation speed optimization" type="info">
+For fastest generation times, enable both `useOxlint` and `useTsgo` together. [OxLint](https://oxc.rs/docs/guide/usage/linter) replaces ESLint with a Rust-based linter that processes files in parallel, while [TSGo](https://github.com/microsoft/typescript-go) replaces `tsc` with a native Go compiler that delivers up to 10x faster type checking. Combined, these tools can reduce SDK generation time by up to 35%.
