| Kai's verdict | S-tier for open-source model APIs. The default in this space. | S-tier for text-in-image. Use this for posters, Midjourney for art. | A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. |
