Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier if you already pay Gemini. B-tier standalone.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
