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 for data teams. S-tier if you already live in SQL + Python.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
