Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Google-only Can be slow on large corpora	Pricey for serious volume Long shots still feel off Ethics — easy to misuse	English quality behind Claude/GPT Less well-known outside Asia
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
