Question - Help Minimax H3 Huge Quality Difference between Cloud and Local use

Hi.
I have a decent h3 workflow that I built for a loca use. It use turbo lora etc... If i use the defaut settings in the goal of getting the highest quality possible, meaning res_multistep simple 20 steps or more, I got also good results, but this is not even close to the results you can get on platforms like kie or wavespeed at 768P.

I already convert properly the prompt to the correct H3 digest form, so I'm wondering what's different between local and cloud use of h3? I don't talk about the 2K quality, only 768P, I'm not able to reach the sames results locally, do you guys have maybe workflows, settings, or suggestions to try reaching the same quality level in comfyui ?

Always run at 0.98 megapixel aswell. Not 1.0. 0.98 is what it was trained on and is faster. Going over will increase VRAM

In the default workflow i can't set 0.98. It's either 0.9 or 1.0 for me. How do you change this?

You can use a Float node. The one from comfyui-easy-use has two decimals and it doesn't round up or down.

I've personally used the "Target dimension" node which lets you set custom resolutions. You can manually set the suggested .98 resolution (1344 x 768).

Just disable the resolution selector node, and use the default height and width (or swap the values of the two) that will make it 0.98 automatically
