| Kai's verdict | 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 for fiction. If you're writing a novel, this beats raw ChatGPT every time. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
