Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.A-tier for sales teams. B-tier for solo users.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
