| Kai's verdict | S-tier for realtime. If latency matters more than voice catalog, start here. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier inside Photoshop (Generative Fill). B-tier standalone. |
