I was curious which of the three major US AI labs generates images that people like more, so I built ImageDojo.ai.
It shows you two images side-by-side, both generated from the exact same prompt. You vote on which one you like more (you don't see the prompt or which model made each one).
Based on the votes, it calculates ELO ratings for the models — similar to LMSYS Arena for text.
The four models I selected (the original and the new Nano Banana, GPT-Image-1.5, and Grok-Imagine-Image) are all in the same rough price range ($0.02–$0.06 per image), so we're comparing fairly similar-class models. Please try it out and let me know what you think!
