Pi is known for being minimal. We care about holding that line. While agentic tooling changes every week, many of the changes do not last. Pi does not work that way. We wait until something has proven itself, and only then do we consider adopting it; weighing its true functionality against its inherent added complexity. We spoke more about that process and how it relates to Codemode and MCP earlier this week here.
The Pi 1.0 we are shipping today is a result of that process. Pi already ran the latest models from every major provider, became a daily driver coding agent for people around the world, and provided a supermalleable substrate on which to build agentic applications. With Pi 1.0 we are adding the following into Pi:
We have thought about many of these features for months. They were thrown up against the wall and stuck. The list of things that fell off the wall is much longer. When we use Pi with all these new features it feels like a major step forward, but it also still feels simple, like Pi.
Alongside this work of continually refining and evolving Pi, we also began to understand that there were aspects of Pi that did not fit the shape of how many people wanted to use it. At Earendil, we want to bring Pi’s minimalism and the way it allows you to wield AI outside of the coding agent and outside of the terminal. It needs to be reachable from different surfaces and support longer-running conversations and tasks. In short, Pi must become more durable. Rather than stray from our minimal roots and try to make Pi something it wasn’t, we combined that work into a new experimental package that we are shipping today, Pi Durable. Pi Durable is a new substrate for building long-running agentic applications that lets the builders and the users of those applications wield and steer the underlying intelligence with tremendous dexterity. It shares Pi’s key principles, minimalism and supermalleability, but it extends those principles into new dimensions. Mario writes in more detail about how we crafted Pi Durable here.
Earendil was formed to craft software and open protocols that strengthen human agency. Today we are shipping tools to you all to help do just that. We’re eager to hear feedback from you and to harness the future out in the open together.
