Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.A-tier for data teams. S-tier if you already live in SQL + Python.
