Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-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.S-tier in the agent category. The first one I'd give to a non-technical friend.
