Today Earendil and the Pi community shipped Pi 1.0. This reflects our belief that after countless hours of hardening, maintenance, and active development, Pi is now a solid foundation on which to build. Together with Pi 1.0, we are shipping an experimental new package called Pi Durable, built specifically for long-running, durable, and malleable agents that can run anywhere.
Why Pi Durable? Pi the coding agent is built to run on your (remote) machine, inside a terminal, driven by one person. At Earendil, we want to bring this technology to everyone. For that, we need a harness that runs anywhere, can be reached from different surfaces, supports infinitely long conversations, survives catastrophic failures, and lets multiple humans steer the same agents. Pi Durable is that harness.
A harness is storage plus the machinery needed to run one or more conversations with large language models in parallel. The entire source code is about 15,000 lines, which comes out to about 150,000 tokens with GPT. The storage backends alone are 3,000 lines. Pi Durable ships memory, SQLite, and JSONL storage, plus a conformance suite for your own backend.
