Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
