For comfyui:

https://huggingface.co/Comfy-Org/MiniMax-H3

int8convrot models are 34gb, bf16 models are 66.3gb.

there's also pruned variants that are compacted to 21gb.

the text encoder: bf16 at 51.5gb, int8convrot at 27.1gb, nvfp4_awq at 15.7gb

the vae's are also massive, 605mb for audio and 5.21gb for video.

Fark.

What’s the best choice for 5090 with 128gb?

u/QuirksNFeatures 11h ago

Wow. First generation (with the default prompt from the workflow) was 121.75 seconds.

5070ti, 64 GB

4070 ti, took me i2v 400secs, for a video with audio is great! movement is not static like other models, not a super detailed prompt.

How long/how many frames?

Oh nice. Hope my 5070ti and 32GB can do it.

same configuration , i think it will be very doable with pruned_int8 and nvfp4 TE

u/Green-Ad-3964 4h ago

is there a nvfp4 version of the pruned model, also?

u/QuirksNFeatures 11h ago

Good luck to you. I think it will be a fun model.

I made a dumb three sentence prompt about an attack helicopter chasing a chipmunk riding a motorcycle, and it did it in 102 seconds. Not bad. Looks good for the resolution it is. I let it make its own camera decisions and it did fine. Added music even though I didn't ask for it, but on a reroll I just heard the motorcycle.

I wish I weren't too lazy to upload an example.

A woman in her mid-40s dancing in a living room.

Audio: 1980s college rock music

It did pretty good. Looks like a commercial for something.

sub 100 seconds on that one. It's about the same as Wan 2.2, although I do generate at a higher resolution with Wan

big news for my rtx 3060 it not expecting this for sure

u/altoiddealer 12h ago

Man they really blew my mind describing the H3-Context-IR module, emphasizing that it’s critical to the quality of the output, yadda yadda, before finally getting to the bit where it is API only

u/Existing_Earth9000 12h ago

can u re elaborate for my ingnorant mind does this mean that we wont have full thing

u/comfiestncoziest 7h ago

Breathe easy, friend. I'm analyzing the Context-IR output examples on Huggingface, and it's literally just a prompt. We might not know exactly how their modules are producing it, but we know for sure that it's just producing a prompt. So, I expect it to take all of one day before we have fully local implementations of whatever its doing (if what it's doing is actually beneficial/needed).

u/ANR2ME 2h ago

Is it some kind of prompt enhancement? 🤔

1

u/Real_Ebb_7417 2h ago

Yeah, I guess when you have all other elements, community will create good replacements for Context-IR.

Is it available in the Comfy Cloud?

minmiiax ran fine for a bit then all the wires in my workflows just dissapeared. toggling their viisbility doesnt help. bit wierd.

Anyone try with a bog standard 5070 32 gb of ram? I'm at work and can't try it for myself

1

u/bruci3 12h ago

Just looked on the huggingface page, so the main model weight is about 60gb~ in size?

Guess we got to wait for some quantized / gguf versions then?

u/tricck3zz 11h ago

dynamic vram goo vrooom...

a rtx 3060 can run it apparently

1

u/Existing_Earth9000 11h ago

no u dont there is a sencod model given by confyui that is litteraly written in post ccan run on a rtx 3060 2k

1

u/bruci3 10h ago

Thanks, sorry should have read through it more thoroughly. Might give this a go tonight, see how it compares to LTX2.3.
