| Kai's verdict | S-tier for open-source model APIs. The default in this space. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. |
