Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier infrastructure. The one platform every AI dev eventually uses.
