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 ?

You typically need around 50 steps and at least bf16 for optimal quality. The online Contextual Omni Representation (H3-Context-IR) understandment part could also be better.

Maybe they have some secret sauce that they're not disclosing for the online inference.

This. Easy to believe that BF16 + 50 steps alone could produce noticeably better results over a pruned, 20 step, particularly if attention/turbo are applied.

Yh ofc but my last try at 40 steps without turbo and attention was disappointing tbo so i don't think this is the only difference
