Pi 1.0 ships a hardened, minimal agent harness that stays simple
Earendil releases Pi 1.0, a hardened, minimal, extensible agent harness used by hundreds of thousands weekly. The update adds Codemode with native MCP support, virtual-model extensions, deferred tool loading, Anthropic cache warming, mid-conversation system messages, a new TUI theme, and full-screen mode. The team also introduces Pi Durable, an experimental substrate for long-running agentic applications, available via npm and MIT licensed.
We wait until something has proven itself, and only then do we consider adopting it; weighing its true functionality against its inherent added complexity.
