I found MiniMax-H3-Turbo-Lora ~ 4-step
I found MiniMax-H3-Turbo-Lora, but it's currently in training. The authors released one weight, but it doesn't yet support ComfyUI.
MiniMax-H3 Turbo LoRA — 4-step audio-video generation (early preview)

minimax_h3_turbo_4step.safetensors
It currently cannot be loaded in ComfyUI; could you convert and test it to see if it actually works?
4-step sampling would significantly boost generation speed.
Waiting for 8 steps to accelerate LoRA
It worked well for me after I used this script.
import sys
from safetensors.torch import load_file, save_file
input_lora = sys.argv[1]
output_lora = sys.argv[2]
src = input_lora
dst = output_lora
lora = load_file(src)
out = {}
for k, v in lora.items():
new = k
if (
k.startswith("blocks.")
or k.startswith("token_refiner.")
or k.startswith("final_layer.")
):
new = "diffusion_model." + k
out[new] = v
print(new)
save_file(out, dst)
print("done")

8 steps and lora strength 1.8 res: 1280x720 + RTX Super resolution.
8/8 [06:16<00:00, 47.03s/it] On a RTX 4070ti super 16 gb vram and 32gb ram.
Don't work with the pruned model.
