| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. |
