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 study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
