Run Pi on CSM 1B
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.
