## AI overview

Chainguard describes how its Factory uses automation to manage toolchain version selection, upgrades, builds, and testing across open source packages. The approach uses version streams and rebuilds packages with newer toolchain versions when builds and tests succeed, helping deliver updates quickly while maintaining reliability and security.
