Overall Value
BAML isn’t another LLM playground—it’s a developer-first framework built for scale. Think of it as infrastructure as code, but for AI applications. With a simple yet expressive DSL, BAML lets you define logic, compose LLM calls, run tests, monitor outputs, and ship reliable, reproducible AI-powered apps with full observability.
BAML Product Review
Key Features
- Domain-Specific Language (DSL)
Write structured app logic using a simple YAML-like language that’s expressive, testable, and easy to version. - Multi-Model Composition
Seamlessly connect OpenAI, Anthropic, Cohere, and local models into unified chains with branching logic and fallback support. - Built-in Evaluation System
Test your chains using custom test cases and metrics like latency, cost, and correctness, built right into the workflow. - Version Control Friendly
BAML is designed for Git—track changes, collaborate across teams, and deploy confidently. - Production-Ready Execution
Run workflows locally, in CI/CD pipelines, or deploy at scale with cloud-native flexibility. - Monitoring & Logging
Debug every prompt call, view outputs, track costs, and measure performance—all in one place.
Use Cases
- Engineers deploying complex LLM workflows in production
- AI teams maintaining chains with version control & observability
