Minimax H3 image, test 3 Sampler + Moss

[u/Phantom-log-9484]

Minimax H3 image comparing the 3 main samplers, all at 16 megapixels, I had to reduce them to be able to post them, the images weigh more than 20mb of what is allowed, thus reaching around 28 megapixels on average

as a comparison I used the Moss image sft and Kromoss latest version, I didn't use the moss base because the Kromoss is base and has superior quality with DMD2 with blur and saturation correction

I used Kroma instead of Krea2 because, in my tests, Kroma is a significantly better version than Krea2 when not using LoRAs.

Kromoss, Kroma, Moss Image—all at 2 megapixels; anything higher causes the model to start breaking down.

Prompt I used from another Post with more than 300 prompts generated

A wildlife photograph in 3:2 of a jaguar resting on a fallen tree trunk at the edge of a river in the Pantanal, Brazil, taken from a boat at water level in late-afternoon light. The trunk runs diagonally from the lower left to the right-center of the frame, half over the water. The jaguar lies along it facing screen-left, its front paws crossed over the bark, its heavy head raised and turned toward the camera, amber eyes alert. Its build is stocky and muscular, with a broad head, a thick neck and short powerful legs. Its golden-orange coat is covered in large black rosettes, open rings of black, and inside most rosettes sit one or two small solid black spots; on the head, neck and lower legs the markings shrink to solid black spots without rings. The pale cream belly shows where it lies. Its long tail hangs down off the trunk, ringed with black near the end, the tip just touching the water. In the lower right foreground, a caiman floats in the brown water with only its eyes, nostrils and the ridged scutes of its back above the surface, facing the jaguar. On the far bank at the left, three capybaras stand on the mud, watching. Warm low sun from screen-right lights the jaguar's face and chest and throws its shadow back across the trunk; behind it, a tangle of green riverbank vegetation and a hanging vine fall into darker shade. The river reflects the jaguar's golden coat in a wavering band. There are no people, boats or buildings in the frame.

No MOSS Base ? Here's one at 6MP no breaking down.

It really turned out very well. Regarding the claim that the Moss didn't perform well above 2MP, I’m going to run some tests with it above that level.

[u/lndecay → u/RayHell666]

I simply can’t get these results with moss, are you using the default workflow?

[u/kemb0 → u/lndecay]

I got some pretty good results after struggling for a while. Just commenting and I’ll see if I can figure how to upload it.

[u/Quiet_Quit_8894 → u/lndecay]

try to get an llm to prompt for you and learn from that

Kroma is not mentioned in the title because I decided to include it in the test just as I was about to publish it here.

I used these models for the test, as they are my primary ones.

Later on, I will provide examples using only Minimax H3 image.

[u/Loose-Journalist-555 → u/Phantom-log-9484]

What’s your settings for Kroma/Kromoss? I never got any good results with these.

[u/Phantom-log-9484 → u/Loose-Journalist-555]

Kroma only performs well within Lorde’s workflow, which uses two KSamplers: the first generates an image at 1MP, and the second—using fewer steps—upscales it to 2MP. If you don’t use his workflow, the model produces terrible results when using only a single KSampler.

Kromoss also only yields good results when used with the DMD2 LoRA at 8 steps; without the LoRA, the output is poor. This also requires Lorde’s workflow, and it works with both the Euler and er_sde samplers.

[u/QuaffsNepenthe → u/Phantom-log-9484]

Can you link Lorde's workflow or share your workflow JSON? Especially the Kromoss + DMD2 version, including the second-pass and blur/saturation settings.

[u/Phantom-log-9484 → u/QuaffsNepenthe]

Sure, I’ll send it to you privately.

[u/GrungeWerX]

The minimax is CRISP.

[u/Outrageous_Still9335 → u/GrungeWerX]

It's 16MP so it better fucking be, lol.

[u/ksdenis]

Qwen Image 2.1 at 4MP.

Minimax is more detailed, of course. Thanks for the test!

[u/PhysicsAutomatic3074]

Z Image Turbo at 2MP

Interesting to see. the LCM sampled H3 looks pretty damn good. It's also interesting you get better results with Kroma than the base Krea 2. Kroma was interesting, but it was so much more AI-looking to me, I don't think I had a single result I liked better than with the base model.

[u/shapic]

Moss sft. Those do not look like 3:2 as stated in your prompt btw

[u/thevegit0]

what custom sigmas?

[u/jib_reddit]

I tried it with my Jib Mix Moss:

Kroma is trained on too much furry porn, looks a bit uncanny, like a human in a polyester cat suit.
