About ypi

ypi ypi — a recursive coding agent built on Pi. Named after the Y combinator from lambda calculus — the fixed-point combinator that enables recursion. is Pi that can call itself. ( already has another connotation.) Inspired by Recursive Language Models (RLM), which showed that an LLM with a code REPL and a function can recursively decompose problems, analyze massive contexts, and write code — all through self-delegation. The Idea Pi already has a bash REPL. We add one function — — and a system prompt that teaches Pi to use it recursively.
