Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.S-tier for local inference. If you care about privacy or want to tinker, install this today.
