Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Niche but beloved. If you've outgrown Notion, try this.	A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
