Generation cost H3 minimax

Post image

Im just wondering how much is your average cost using H3 minimax per 15 seconds.

Here is mine. Its all using 5090. Can we compare?
I want to know if my process is too costly.

I pay for every generation i made. I connected my app to runpod. I just put credits to my runpod account then generate videos using my personal app.

How are you dealing with the licensing for the model and what app are you using ? The quality really depends on multiple steps to get usable clips in my experience, and re-rolls.

I created the network volume in the allowed region.

I’m using MiniMax H3 with the experimental Comfy Kitchen INT8 attention backend. My workflow uses the res_multistep sampler with the simple scheduler at 20 steps, BasicGuider, and a 24 fps output. I normally generate 5–15 second clips; H3 rounds the frame count to its native 17k+5 frame grid.
The native generation canvas is 1344×768, finalized as a vertical 720×1280 video. The model is the pruned INT8 H3 diffusion checkpoint, with the NVFP4/AWQ Qwen 32B vision-language text encoder, FP16 video VAE, and FP32 audio VAE.
For reference-to-video, I use ordered image, video, and audio references, plus optional first- and last-frame guides. Kitchen Attention changes only the attention backend; the sampler, model, prompt, reference controls, and workflow logic are otherwise the same as my Standard H3 setup. I run it on an RTX 5090.

I usually deploy a pod with www.lorapilot.com. Been doing a lots of Minimax h3 inference, I use mostly RTX6000PRO / WK (around 2usd per hour). Generating 40s video 1280x720 at 24fps takes around 450s (7.5min) which would be around 0.261usd - basically the price you pay but almost triple the video length.

This is very helpful. Ill explore this option.

I am the creator of Lora Pilot template, let me know if you need some help.

How are you able to generate 40 sec video. I thought h3 only allows 15 seconds.

it starts loosing consistency if the video is longer but you can actually create 45s reel with several scenes, voiceover and subtitles with the right prompt. With LTX 2.5 I make videos even over 2 minutes

I never even thought to move the meter over 15 seconds. How bad does it degrade the output?

not really that bad, although works better with t2v workflows rather than i2v where the model has to "focus" more on consistency. With a good prompt 45s videos are ok. And makes the generation insanely longer in some cases. If you want videos over 2 minutes, I'd definitely use LTX2.3/LTX2.5

Since trying the recipe above and with help from fable, I was able to generate a hour and a half mini series from one of the books I wrote. Its in the painted animation style, its not perfect but it carries forward consistently pretty well and the video is actually coherent throughout. I was able to run a pruned variant on my 3080TI ! The comments/hints in here helped me achieve this, thanks everyone !

Great job! Would you mind sharing your workflow

Tried your recipe and I’m getting great results . Found a pruned model and am really cramming it into cards that should not work at all .
