https://zoo.replicate.dev/ used to be a good site for stuff like that (they ran all of the ai image generation models on the same prompt so you could compare) but it seems they've removed that feature. You still can generate singular images on their homepage tho

The new Bing image generator is probably your best bet. For example:

big chungus riding a low-ride motorcycle in a fallout-new-vegas style desert environment, pixar animation style image, high quality, wearing sunglasses

Show

Disney's corporate lawyers appear to have successfully scrubbed the internet of all the Pixar generators as far as I can tell
