[Collaboration & Test] Hello Kitty T-Shirt

For the fifth image in Santolina's "Hello Kitty T-Shirt" post (https://www.aipictors.com/posts/774168), the original background instruction was simply "an early summer riverbank." Believing that modern AI would yield better results with more specific details, I changed the prompt to "an early summer riverbank along the Ina River"—a spot I occasionally pass during my bicycle commute—and tested it across multiple models. * Included here are the generated images (which vary by model), the specified conditions, and the cost per image based on today's rates. * The unit cost reflects the 50% discount from my annual "Advanced" plan subscription at openart.ai; costs would be higher under different subscription plans. * While services like fal.ai might offer lower costs, I deliberately chose openart.ai because switching only the model while keeping the image and prompt constant is cumbersome elsewhere. * I really wanted to try Flux.2, but it seems that any model using that name was blocked—likely due to trademark issues. I had to settle for the year-older Flux.1 [Kontext Pro] instead. * Since Seedram requires a minimum resolution of 2K, a vertical orientation resulted in an awkward composition, so I opted for a horizontal layout. * On the openart.ai site, points used for blocked generations are immediately refunded, so there was no actual cost incurred for those attempts.

Regarding the detail Santolina-san was concerned about—keeping the shirt untucked—many of the models successfully achieved this; however, I noticed significant changes in facial expressions, such as variations in how the eyes are closed. Models (a), (b), and (e) clearly "know" the Inagawa River area; they likely referenced photos from sources like the river management office. Image (e), in particular, features a composition facing northwest from the opposite bank of Sonoda Racecourse—a view that matches my own memory of the place. Image (a) shows a location slightly further upstream, featuring apartment complexes in Itami City and a residential area in Ikeda City on the opposite bank. While (b) is difficult to pinpoint due to the lack of buildings, I suspect it is slightly downstream from (a), likely near the run
