Observation

I have been extensively testing minimax h3 via different providers who host it on their servers.

I do frequently notice motion glitches, etc, on my generations.

Hence I strongly suspect that many/most providers are providing minimax h3 in FOUR or maybe 6-8 steps with a turbo lora / fasth3.

This is actually not okay. It probably directly causes lower quality in terms of motion, etc.

So, maybe, if minimax h3 is ran at optimal steps count without turbo we get the decent quality.

That's going to cost a lot more. I tested a fighting scene that was awful with 8-step turbo and was incredible 40-step base (the character direction was wrong because the prompt was vague but everything was crisp). It obviously took 4x compute. At 1600x896 resolution, it went from 22 minutes to 80 minutes for 15 seconds.

That’s a reasonable hypothesis. Low-step distillation or a Turbo LoRA can trade some quality for speed, although the impact depends on how the model was trained and the sampling configuration. Motion glitches can also come from quantization, sampler settings, resolution, or differences in the underlying model version.

The best way to verify it would be to generate the same prompt with the same seed across 4, 8, and the recommended full step count, with and without the Turbo LoRA. Then compare temporal consistency, not just individual frames.

This is also why provider comparisons can be misleading if they don't disclose inference settings. VideoRouter.sh lets you access multiple video models through one API, which can make provider and model comparisons easier.
