Prompty Python Runtime

Prompty is a new asset class and format for LLM prompts that aims to provide observability, understandability, and portability for developers. It includes a specification, tooling, and a runtime. The Python runtime (current version 0.1.50) allows developers to load, render, parse, and execute Prompty files within Python applications. It's actively developed by Microsoft, with distinct release cycles for its Python, C#, and TypeScript bindings.
