Pipelex

Pipelex is the open-source language for building and running deterministic, repeatable AI workflows: think Dockerfile for multi-step LLM pipelines.

Pipelex delivers production-ready AI workflows by replacing complex, unpredictable LLM prompts with structured, manageable steps (pipes). This open-source language uses human-readable `.plx` files and Concept-Driven Design (semantic typing) to ensure consistency and logical flow. It solves the reliability problem: developers can now test, validate, and deploy complex agentic flows, like invoice extraction or contract analysis, achieving 99% accuracy and deterministic results at scale.
