Thanks! It's probably the same site. It used to only be a showdown of text-to-image models (Flux, Imagen, Midjourney, etc), but once there was a decent number of image-to-image models (Kontext, Seedream, Nano-Banana) I added a nav bar at the top so I could do similar comparisons for image editing.
Honestly it's kind of inconsistent. Model releases sometimes seem to come in flurries - (it felt like Seedream and Nano-banana were within a few weeks of each other for example) and then the site will receive a pretty big update.
Or there's another very similar site. But I'm pretty sure it's yours
