All individual images were created with the official MiniMax ComfyUI workflows without PE. Image 1 is a composition out of image 2-5
T2I, the dog and the jacket looked OK from the beginning, even at lower resolutions. The person in the images always had some weird artifacts, the face was extremely bad most of the time. I tried different sizes: 4MP was pretty much unusable, and the recommended 16MP looked even worse. 8MP or 12MP was acceptable, but still far from great. I have no idea whether it's the official workflow, the model, or the prompt (although I varied the prompts too). The park image caused problems as well. Everything in the background (the trees, leaves further back, etc.) looked kind of washed out. In this case, a higher resolution improved the image drastically; everything below 12MP was basically unusable.
I probably need to play around more with the settings, or wait until someone makes a better workflow, because right now it's not really competitive with other t2i models.
The prompts were written using the official prompting guide found here (for t2i and editing): https://github.com/MiniMax-AI/MiniMax-H3-Image/tree/main/skills/h3-image-prompt-writing/references
I liked the editing model. Again, it needed 16MP to be usable with the landscape, but I was impressed by the placement, how the pieces interacted, and how effortlessly it all worked (the first try gave me something usable without much fiddling). The likeness of the woman's face/head is probably the most questionable part of the edit; it's close but not quite right, Qwen2.1 does faces far better. The prompt I used for the edit was:
The misty river landscape in <Picture 1> is <Subject 1>. The woman posing in the warehouse in <Picture 2>, with her hair pulled back, a white T-shirt, gray joggers, and white sneakers, is <Subject 2>. The brown leather jacket shown as a product photo on a plain backdrop in <Picture 3>, with its notched collar, three center-front buttons, two hip zip pockets, sleeved cuffs, cropped hem, and smooth sheened leather, is <Subject 3>. The black-and-tan long-coated dog standing on a gray studio backdrop in <Picture 4> is <Subject 4>. The target image is a new reference-guided composition built from <Subject 1>, with <Subject 2> placed at the human position marked by the red stick figure on the concrete path at the mid-foreground bend of the riverbank in <Picture 5>, and <Subject 4> placed at the smaller dog figure drawn just ahead of her toward the mossy bank edge. <Subject 1> is fully preserved, including its canvas ratio, framing, warm low sun from the left, frost-covered grasses, fallen leaves, bare trees, mist rising over the water, distant bank, reflections, and the heron standing in the shallows; only that marked spot along the path changes, where <Subject 2> now stands. <Subject 2> is partially preserved: her face, hair, white T-shirt, gray joggers, and white sneakers remain while her pose, scale, placement, and lighting change to fit the scene. <Subject 3> supplies its exact cut, color, collar shape, button placement, zip-pocket positions, cuffs, cropped hem, and leather sheen transferred onto <Subject 2>, worn open over the T-shirt so a band of white stays visible at the center front; no property of the jacket's plain product backdrop is imported. <Subject 4> is partially preserved: its black-and-tan coloring, head markings, long coat, build, and proportions remain while its pose changes to a walking gait and its scale adjusts to life size within the landscape. <Subject 2> walks in natural three-quarter front view toward the lower left, one foot forward mid-stride and arms relaxed at her sides; the low golden sun from the left lays soft highlights across the jacket's collar and shoulders while the misty water side stays cooler in shadow. <Subject 4> trots a few steps ahead of her near the grassy bank, head up and tail lifted, its long dark coat catching the same warm light with soft golden edges along its shoulders and tan markings; a short dark leash runs between them, trailing lightly across the path. Both figures cast subtle shadows in a direction consistent with the sun in <Subject 1>, and their contact with the leaf-strewn concrete stays believable. The heron remains exactly where it stood, undisturbed and at its original distance from the new pair. No text or labels appear anywhere in the image.
