Pi Durable

Earendil and the Pi community successfully launched Pi 1.0 after extensive development and maintenance. Pi Durable, an experimental package, was also introduced alongside Pi 1.0. Pi Durable is designed for long-running, durable, and adaptable agents that can operate in various environments. It aims to become the best durable harness available and invites users to contribute to its improvement.

Pi 1.0 focuses on running on a user's machine or inside a terminal with a single person driving the process. Pi Durable, on the other hand, is a framework for building agentic applications, including coding agents. It shares code with Pi 1.0 and adheres to similar principles, such as minimalism and malleability. Pi Durable allows for running conversations with large language models in parallel, with tools and execution environments that can be local or remote.

Storage backends like memory, SQLite, and JSONL are included, and the harness interfaces are designed to be easy to implement. The framework ensures that agents can survive process termination and recover from interruptions, making it suitable for long-running tasks.
