| Kai's verdict | S-tier for open-source model APIs. The default in this space. | S-tier for solo + free. The best free option, hands down. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | S-tier for model-shopping. I use this for every prototype before committing. |
