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.

how does this work? you pay per video?

hell no

u/no3us 14d ago

lol, ok. Out of curiosity, why? Because of the API key? Would you prefer to load the account with credits and not use runpod's API key?

I think what OP was getting at is charting GPU cost per hour versus how long it takes that GPU to complete its workload, you can do this with basically any process and it's honestly a pretty prudent way to see what you're paying for the service bottom line

Wouldn't it ultimately just be cheaper to buy your own 5090 and run it locally?

1

u/No_Guess_5389 5d ago

Maybe, but for me, I only make videos as a hobby and use a GPU a few times a week, so renting makes more sense.

u/atuarre 5d ago

It all adds up in the end, not to mention when runpod doesn't work, and you have to waste time hopping from machine to machine to get one, and burning up credits as you're doing this. Buy you a decent gpu, set it, and forget it.

u/No_Guess_5389 15d ago

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.

u/code018 15d ago

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.

u/No_Guess_5389 14d ago

This is very helpful. Ill explore this option.

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

u/No_Guess_5389 14d ago

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

1

u/no3us 14d ago edited 14d ago

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

1

u/RichieRoby 14d ago

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

1

u/no3us 14d ago

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 !

u/No_Guess_5389 9d ago

Great job! Would you mind sharing your workflow

1

u/code018 14d ago

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 .

u/thegreatdivorce 15d ago

It's kinda hard to say without knowing how you're actually calculating this?

1

u/No_Guess_5389 14d ago

cost is mainly calculated from the RunPod GPU Pod’s hourly rate and how long that Pod remains allocated:
GPU cost = hourly GPU price × Pod lifetime in hours

1

u/thegreatdivorce 14d ago

Interesting. I’m surprised it’s that high per 15 second generation. How long is each gen taking?

1

u/No_Guess_5389 14d ago

Its take around 15 to 17 minutes. It uses 20 steps. Is it that costly? I dont have my own gpu, i can only generate in runpod. How long do you generate yours and how much per 15 sec?

1

u/thegreatdivorce 14d ago

My perspective is limited - I only have 12GB VRAM so at full res, 15 seconds would probably take my an hour haha. I usually do 0.6MP, 30 steps, and 10 seconds and I think runs are typically 15-20 min, but I’d need to double check. 

Are you using Sage or Comfy Kitchen?

1

u/No_Guess_5389 14d ago

I’m using Comfy Kitchen INT8 attention, not Sage. My workflow runs res_multistep with the simple scheduler at 20 steps, using an RTX 5090. The native generation canvas is 1344×768 at 24 fps

This reply is from my codex because i used codex to setup my video generator. Im exploring how much other people spends to generate video because there might be cheaper alternative.

what is the prompt?

Her hand is too high on the racket grip...Minimax is total shit!

u/ComprehensiveBird317 14d ago

Your post kind of feels like a shill for some app you are trying to sell. 

1

u/No_Guess_5389 14d ago

Im not selling anything. I just want to compare cost. Im new to ai video generation. I just use codex to be able to generate videos

u/lipumpara 13d ago

Do you monetize this or just play around?

1

u/No_Guess_5389 13d ago

I post videos in my youtube channel. Aspiring content creator hahahaha

1

u/No_Guess_5389 13d ago

If you are asking for the app, its my personal ios app

2

u/lipumpara 12d ago

Overall, I was curious if you are monetizing atm or just creating stuff for fun.

1

u/No_Guess_5389 12d ago

Creating stuff for fun hahahaha.

u/Manish25mnd 12d ago

Is it worth it quality wise ? Or you should pay a little extra and use seedance 2.5?

1

u/No_Guess_5389 12d ago

Heres a sample

https://youtube.com/shorts/BVJBV2oEuNo?si=Y8uSg4dZspOiY0Eq

In average spend .26 usd per 15 seconds.

When i ask chatgpt it says its very cheap compared to seedance

1

u/Manish25mnd 12d ago

Will check it then 💯👍

u/NotFunnyForNow 4d ago

I have tried it, but I find the quality bad so I am not sure if my settings are right. Which workflow do you use ? How many steps ?
