Weaknesses	Smaller community Model selection more limited	Terminal-based — learning curve Can't be used without Claude subscription	UX is rough for English speakers Queue times	English quality behind Claude/GPT Less well-known outside Asia
Kai's verdict	A-tier. Close second to Cursor. If $5/mo matters, start here.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
