Practical overview

When it fits

Use BAML when developing agent functions where structured output, explicit types and errors, concurrency, or built-in testing and evaluation matter.

Who it is for

  • Developers building agent functions that return structured data.
  • Teams that want tests and evaluations in their agent-development workflow.
  • Application developers who want to call BAML functions from TypeScript, Python, Go, C#, or Java.

Documented uses

  • Define typed agent functions for structured outputs.
  • Add tests and evaluations to agent development.
  • Use concurrency features in agent workflows.
  • Call BAML functions from an application written in a supported host language.
Before you choose

Requirements & limits

The public GitHub repository identifies BAML as open source under the Apache-2.0 license. The repository documents a Homebrew CLI installation sequence.

  • BAML can run standalone or be adopted through function calls from TypeScript, Python, Go, C#, or Java.
  • Its documented features include runtime-persistent types, typed and statically analyzed errors, concurrency, and built-in tests and evaluations.
  • The repository's setup sequence uses Homebrew and includes a VS Code integration installation command.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install BAML and initialize a project

Follow the repository's documented CLI setup sequence.

Before you start

  • A system with Homebrew available, as the documented installation command uses brew.

Steps

  1. Install BAML with brew install baml.

  2. Run baml agent install.

  3. Initialize with baml init.

  4. Install the VS Code integration with baml ide install --code.

Expected outcome

The documented installation and project-initialization commands have been followed, with the VS Code integration installation included.

Guide limitations

  • The repository does not specify platform compatibility or further configuration in this command sequence.
  • This is a setup guide; it does not describe running an agent function.
