Weaknesses

Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.
