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.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
