Summary

The author compares several agentic coding harnesses (Codex CLI, Claude Code, Gemini CLI, OpenCode, Pi) and finds Pi the leanest and best for local models, praising its simplicity and compatibility with Qwen 27B-MXFP8.

So far, I’ve tried Codex CLI, Claude Code, Gemini CLI, OpenCode, and recently, Pi with local models. Pi is the leanest of them all, with just four tools: read, write, edit, and bash. Its system prompt is only under 2K tokens, and it's perfect for local models. I've been trying out Qwen 27B-MXFP8 with it, and it's much better than I expected! It doesn't have fancy bells and whistles like multi agents, but the only thing I’m missing is searching the web for documentation. I’m sure you can get it through an extension, but you probably won’t get the same robust search features you get from commercial platforms anyways. This might be my new favorite! What’s yours?
