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.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
