Weaknesses	Can burn tokens fast if not watched Less polished than Cursor	Less agentic than Cursor/Claude Code Model quality varies	Terminal-based — learning curve Can't be used without Claude subscription	English quality behind Claude/GPT Less well-known outside Asia
Kai's verdict	A-tier. Best free agentic option in VS Code. Use with Claude for best results.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
