| Kai's verdict | S-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. | S-tier in its category. The first AI music tool I'd actually listen to. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. |
