Mellea — build predictable AI without guesswork

Mellea helps you manage the unreliable part of every AI-powered pipeline: the LLM call itself. It replaces ad-hoc prompt chains and brittle agents with structured generative programs — Python code where LLM calls are first-class operations governed by type annotations, requirement verifiers, and principled repair loops.
