Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
