Earendil releases Pi 1.0 and experimental long-running AI platform
The company describes Pi 1.0 as a hardened agent harness and Pi Durable as an experimental base for applications with longer-running conversations and tasks.
Earendil has announced Pi 1.0, a release of its agent harness, alongside Pi Durable, an experimental package for building long-running agentic applications. Both are MIT licensed.
The company describes Pi 1.0 as hardened, minimal and extensible. Earendil says months of user feedback and development shaped the release, though its announcement does not detail the features added.
Earendil says Pi supports models from major providers and has been used as a coding agent and as a foundation for building agentic applications. Those adoption and capability claims were not independently verified in the announcement.
Pi Durable is intended to extend Pi’s approach beyond coding agents and terminal use, supporting longer-running conversations and tasks across different surfaces. Earendil identifies it as experimental; the announcement does not establish its production readiness.
Documentation is available at pi.dev, with code at github.com/earendil-works/pi.
