Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
