Pi 1.0
Earendil shipped Pi 1.0, a hardened release of its deliberately minimal, extensible agent harness. New in 1.0: Codemode (native MCP plus non-LLM models), deferred tool loading, cache warming for Anthropic models and transcript-aware mid-conversation system messages. Shipping alongside it is Pi Durable, an experimental framework of about 15,000 lines for long-running agents that survive crashes, run anywhere and can be steered by several people.
