Pi is a lightweight open coding agent from pi.dev. It's a simple, fast terminal agent that edits code and runs tasks from natural-language prompts, built to stay minimal and model-agnostic rather than locked to one provider. On Opper, launch it on any of 700+ models, fall back across providers automatically, and keep everything on one key.
PioninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
