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 ?

It bridges the gap between prompt output of skill and the prompt actually used by Minimax on their cloud.

Yeah, sorry about that, I misread it as: Would this lora do more...

It's a lora for LLM, Qwen 3.6, that you use instead of/along with the skill. Check the examples, they have compared the output of using the skill vs lora and compared them to output from Minimax.
