| Kai's verdict | A-tier. S-tier if you self-host. The reason open-source image gen matters. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
