Choosing an AI image generator by use case
Generate consistent characters and multiple characters
If you are building a story, a comic, or a brand mascot, the ability to generate
consistent characters matters more than raw image quality. The best AI models can hold
the same person across many scenes, render multiple characters in a single image, and
keep a matching image style from frame to frame. Provide reference images so the model
learns the face, then reuse them to generate consistent characters in new poses. Not
every AI image generator does this well, so it is worth testing with a single image
first.
Editing images: image to image and reference images
Editing is where modern image editing tools shine. With image to image you can refine
existing images instead of starting over, upload multiple reference images to guide the
look, and combine images into a single composition. Good image editing also lets you
edit images locally, fix a detail, or restyle a shot without touching the rest. If your
work leans on retouching, prioritize an AI image generator with deep image editing
rather than text to image alone.
Photorealistic and realistic images: image quality first
For ads, ecommerce, and stock images, image quality is everything. The top models now
produce photorealistic images that are hard to tell from a camera, with believable skin,
a clean clear blue sky, and accurate lighting. If you need higher resolution output for
print, check each tool's maximum size before committing. When realistic images are the
goal, Nano Banana 2 and
Flux 2 Max are among the
strongest picks.
Art style, illustration styles, and vector images
Not every project wants realism. For AI generated art, flexible art generators let you
lock an art style, switch between illustration styles, and keep consistent styles across
a set. Some tools even export vector images for logos and icons, which is rare among
image generators. If you want to create visuals with a distinct look,
Midjourney
remains a favorite for expressive, stylized output.
