Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.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.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
