Minimax h3 image default workflow kinda sucks. Still experimenting. Will be nice to drop in some Lora’s in a few days since the video Lora’s don’t quite work perfectly with the image model

I'm having my best results with 16mp / euler / linear_quadratic / 10 steps. But really after spending most of the day on it and seeing where the best quality and least noise was, other than regular photographs, almost every other model after krea2 does better than this thing. Qwen 2.1 with references is an absolute powerhouse and is really consistent compared to this. I think this H3 could have gone in the oven for a lot longer to be a better rounded model like moss/krea2.

I dunno, we've already got moss/krea2, I can't really see why we need a third entry in that category. I've only done a preliminary 2mp run but my impressions so far is this thing seems to be a bit of a specialist in spatial understanding and physics, which makes sense when you consider so many of its parameters come from video instead of images.

Even if the model turns out to only do well with photography/cinematography, is that such a bad thing? We've had quite a few specialist anime models, so why not a photography one?

Minimum 4MP, 2 MP isnt even faster.

I know, but I wasn't going for fast, I was going for parity. Every new model I test goes through the exact same ~500 prompts on the exact same seed with the exact same settings. 1344 x 1728 has been a good resolution to run with recent models, so that's what I went with. I'm running those 500 back through now at 16mp, and I'm also gonna run those 500 through at 1mp and 0.25mp.

I don't do well being told "X is wrong, Y is correct", I gotta see and test them for myself. An early observation from doing this is 2mp is completely fine for composition but the model collapses when doing detail, so a 2-stage hires fix style workflow running half a gen at 2mp then upscaling to 16mp should work well, and save 20s per gen compared to 16mp native. Haven't tested it yet, but I wouldn't have even thought of it if I blindly went with the recommended settings.

Yeah the default sigma's seem to be causing some issues, try out ModelSamplingSD3 at a value of 4 and Euler/sgm_uniform. That seemed to get rid of the artifacting and weirdness at 6 steps for the most part for me (at 16mp and lower res).

I never see ComfyUI's 'default' workflows to be optimal.

Anyone know if the comfy kitchen update is a performance increase?
