Earendil releases Pi 1.0 and experimental Pi Durable agent harness

Alongside this release, Earendil is introducing Pi Durable, an experimental package. While the standard Pi coding agent focuses on single-person interactions within a terminal, Pi Durable is designed for building long-running, durable, and malleable agentic applications. This new framework allows multiple users to observe and steer the same conversations and aims to make agent technology accessible outside of traditional coding environments and terminals.

Pi Durable operates as a harness that manages storage and the machinery required to run conversations with large language models in parallel. It includes built-in support for SQLite and JSONL storage, as well as a Node execution environment. The system is designed to allow agents to survive process interruptions, such as a machine running out of memory or a container being redeployed, by picking up from the last recorded state.
