Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
