BAML: Basically A Made-up Language

BAML is the programming language for agents.

Homepage | Explore BAML | Discord

BAML looks like TypeScript, but every feature is built so agents make fewer mistakes:

  • Statically typed like Rust, with colorless concurrency like Go.
  • Types persist at runtime. There is no any.
  • Errors are typed and statically analyzed.
  • The filesystem describes the modules/namespaces.
  • Run BAML standalone, or call it from any language of your choice (Python, TypeScript, Go, and more).

Explore the website and examples.
