BAML: Basically A Made-up Language

BAML is the programming language for agents.

[](https://pypi.org/project/baml-py/)

Homepage | Explore BAML | Discord

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

- It has a type system like Rust, but compiles even faster than Go.
- Types persist at runtime. There is no any nor casting dangerously to any type.
- Errors are typed and statically analyzed.
- The filesystem describes the modules/namespaces.
- Has green threads, and colorless concurrency like Go
- Built-in tests / eval framework
- Built-in stdlib for agents
- Every baml tool is natively designed for agents, with no garbage outputs, etc.
- Can be run standalone or adopt incrementally (you can call a BAML function from TS, Py, Go, C#, Java, etc).
