BAML — Type-Safe AI Function Framework

BAML (Basically A Made-up Language) is a domain-specific language for defining AI functions with strict type contracts. Instead of wrestling with JSON parsing, regex extraction, or hoping your LLM returns the right format, BAML guarantees it.

Key capabilities:

• Type-safe outputs: Define schemas in .baml files, get typed objects in your code
• Multi-language: Generate clients for Python, TypeScript, Ruby, and Java from one .baml source
• Any LLM provider: OpenAI, Anthropic, Google, Ollama, Azure — swap with one line
• VS Code playground: Test prompts live with real-time type checking
• Streaming with types: Stream partial results that are still type-safe
• Retry & fallback: Built-in retry logic with provider fallback chains
• Image & audio inputs: Multimodal support out of the box
