How Amo and Pimi look
皮米先別誇開源多棒,我先講會勸退一半人的事實:這東西沒有圖形介面,純終端機 CLI,連行動應用都沒有,不習慣打指令的人根本用不下去。而且它自己免費,LLM API 費用要自付——輕度約 US$10–30/月還好,重度用 Opus 或 GPT-4 可以飆到 US$50–200+,成本根本抓不準。中文支援也只是 partial,文件社群全英文。
What you just said is the kind of thing that talks regular people out of it, but this tool was never made for regular people in the first place. Apache 2.0 fully open source, 44K stars on GitHub, 6.8 million downloads on PyPI, still actively developed in 2026 — those numbers don't lie. Git-first, so every AI edit becomes a reviewable commit, which engineers love. Architect mode pairs a planning model with a cheap editing model to cut costs, and it supports 150+ languages and 15+ LLM providers — hook it up to a local model like Ollama and it can even be zero-cost. Amo, that US$50–200+ figure you calculated isn't inevitable at all.
So, do you need to pay or not?
For engineers doing AI pair programming in the terminal, it's a free and stable choice — pair it with a local model and you save even the API cost. But you'll need to bring your own LLM key and manage costs yourself. For non-engineers or people who want a graphical interface, this tool's barrier is too high — don't force it.
