| Pricing | Pay per second of compute | Free + included with Creative Cloud | $500/mo | Credit-based, free trial |
| Best for | Developers using open-source models (Flux, SDXL, Whisper, etc). | Anyone in Creative Cloud. Brands that need copyright clarity. | Engineering teams offloading tickets. Ops/platform work. | Anyone who wants top-tier video quality for less. |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. |
