Using AI to make Art:
It's fun to make. Sometimes with unexpected results. It's still early days of AI so you'll have to sometimes contend with images with extra limbs or missing limbs; or illogical contortionist poses.
Canva AI gives good results quite quickly.
I like to use it to make fun playlist cover images.
Deep Dream Generator has a specific style. Not for everything but special in its own way. Maybe it's that dreamy quality.
Leonardo AI has a tasteful style which I like a lot. The images turn out well without much fuss.
PixVerse AI is fast and easy. You can upload your own images as references and then alter them or create new ones.
I use it a lot to fill-in and colourise images.
Deep AI looks amazingly good. I like the sultry character it has.
Runway ML is mainly for developing advertising material (rather than creating images). You need reference images to start.
