| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Close second to Cursor. If $5/mo matters, start here. | A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA. | A-tier. Best for fast prototypes. Competitive with Lovable — try both. |
