Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.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.S-tier for designers. The only one that takes vectors seriously.
