BoundaryML/baml

BAML is an AI framework that transforms prompt engineering into schema engineering, enabling developers to build reliable, type-safe AI workflows and agents across multiple programming languages.

Core Features

Transforms prompt engineering into schema engineering for reliable LLM outputs.

Supports multi-language integration (Python, TypeScript, Ruby, Go, C#, Rust, Java).

Provides full typesafety, streaming, retries, and reliable tool-calling for LLM functions.

Offers native IDE tooling (VS Code, JetBrains) for rapid prompt testing and iteration.

Treats LLM prompts as functions with defined inputs, outputs, and model configurations.

Quick Start

pip install baml-py

Detailed Introduction

BAML (Basically a Made-up Language) is an innovative AI framework designed to bring engineering rigor to prompt engineering. By treating LLM prompts as functions with defined schemas, BAML enables developers to build highly reliable and type-safe AI workflows and agents. It supports seamless integration across a wide array of programming languages, including Python, TypeScript, and Go, and offers features like streaming, retries, and robust tool-calling. With dedicated IDE tooling, BAML significantly accelerates the iteration and testing of AI pipelines, empowering engineers to develop sophisticated AI applications with greater efficiency and confidence.
