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).
