Show HN: Imagedojo.ai – Blind arena for Google, OpenAI, and xAI image generators

[vtail]

Hi HN,

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!

For reference, have you seen the Artificial Analysis Image Arena Leaderboard? They also show you two images from anonymized models (shows after you vote), and calculates crowdsourced ELO ratings.

Thanks - and no, I haven't seen this one. I like how they have the edit mode dashboard - show the original image + two edits; I was thinking about doing something like this.

I'm also a bit surprised they have gpt-image-1.5 so high above Nano Banana 2 - my limited testing shows that, at least for the visual styles, people like Nano Banana more.
