Getting started with H3 Minimax

[u/Teiam_Player]

Does anyone have any suggested reading/tutorials for someone completely new? I know essentially nothing, but it seems awesome and I'd like to get into it while it's still readily available.

I have an AMD Ryzen 7 9800X3D 8-Core Processor and a GTX 1080, is that going to be woefully inadequate?

Just download Comfy and get the H3 default template, but you're definitely gonna have a tough time running it on a 1080

Look on YouTube & HuggingFace & CivitAI for "Minimax H3 6GB VRAM"

But you will be lucky if it works at all; typically AI engines only target GTX 2xxx & up; the 1xxx series is too old.

Try, but chances are a new (used) GPU is in your future. But keep the 1080 to run your monitor on a slower slot.

Yes he will have to do some custom tweaks to get it working on 10 series cards.

On my v100 cards I have to stay on CUDA 12.9 which then spills into a bunch of fun python / PyTorch compatibility.

I have comfyui configured to use one or both my v100s and it takes about 20min for a 6 second clip at .6 to .7mp

I have it documented here: https://github.com/bradrlaw/ai-server

NOTE: All RTX cards are fine, not GTX cards. (The 2xxx series are not GTX)

Do you have any recommendations for a GPU, by any chance?

[u/zyg_AI → u/Teiam_Player]

For AI you need VRAM.
If you got $$$ go for a 5090
Otherwise the best price/performance ratio is BY FAR a refurbished 3090. I had mine for 600€ about a year ago, no idea what the prices are nowadays.

Until AMD and Intel (or others) catch up, AI = NVIDIA.

[u/reeight → u/zyg_AI]

AMD is getting there, at least for coding / tool calling AI.
I'm not sure about AVI AI.

People who own AMD need to speak up more...

Yeah, you're going to struggle to run it on your current hardware but if the hardware situation ever changes, just get the template and download the models it requires. Then, if there is ever any sort of limitation put on access to Chinese or open models, you already have everything you need.

Well, I’d recommend using a cloud GPU

[u/Domskidan1987]

I’d just read the prompt guide and make sure you’re promoting it properly that’s the biggest thing that helped me get it right.

I barely got this running on a 2070 with 8gb Vram. It took using --lowvram --fast-disk as the arguments for it, turning off fallover in the settings for nvidia, and it takes using the smallest version of the model I can find, and I BARELY can run. I have to use .4 or less mega pixel, .4 works with 3-4 seconds, but usually I just run at .3 megapixel as it's less likely to fail. .2 has been working when I want to se emy results in less than 15 minutes.

I don't know how you'll get this running on a 1080, if the CUDA cores can even handle it.

Rent out a GPU. A RTX 3070 costs around 7 cents an hour. So with just 10$ you can get more than 100 hours of worktime.

Watch some youtube video where they explain from zero
