Prompt Engineering and Dev-Ops toolkit for applications powered by Language Models

Hello, I'm PDX 👋

PDX is a framework for prompt engineering and a dev-ops toolkit.

At the core, it provides a mental-model on how to build and manage agents. An agent is a collection of prompts and/or prompt templates with information that is used to interact with the Language Models.

Documentation: pdxlabs.io/docs
