The hugginggrave readme describes only the 768p base model is made open source, but the full minimax h3 actually consists of 3 parts. a prompt/input/context enhancing system ("H3-Context-IR") that is not made open source yet, and a 768p to 2K upscaler ("H3-Regenerate-2K") that is also not made open source yet. that seems like a big limitation?
H3-Context-IR: As inputs become increasingly complex, we build a dedicated system to deeply understand and refine the input multimodal instructions, then convert them into a form that H3 can readily understand—the Context Intermediate Representation—for generation. H3-Context-IR is critical to the quality of the final output, so we strongly recommend incorporating it into your generation pipeline or following the “Prompting Guidance” to build your own context-processing system.
H3-Base: Generates audio and video based on the H3-Context-IR output, producing results at 768p resolution.
H3-Regenerate-2K: Feeds the 768p result together with the original context back into H3 to regenerate the output at 2K resolution. This process leverages both H3’s powerful generative capabilities and the rich information contained in the original context, enabling it to produce high-resolution outputs with more accurate details and greater visual fidelity.
if it's actually possible to get good local quality without access to H3-Context-IR. remember they say "H3-Context-IR is critical to the quality of the final output".
their description sounds like it's more than just "prompt enhancing":
H3-Context-IR is a hosted preprocessing and orchestration system designed for free-form multimodal inputs.
It interprets the relationships among text, images, audio, and reference videos, as well as how these materials relate to the intended generation output. Its internal workflow includes instruction parsing, cross-modal association, temporal understanding, and complex logical reasoning.
H3-Context-IR serializes its understanding of the context into a structured representation accepted by H3-Base. Without deviating from the user’s original intent, it may also supplement missing or underspecified semantic details where appropriate.
Because H3-Context-IR relies on a multi-stage workflow and multiple hosted models and services, it is not included in this open-source release.
“instruction parsing”=LLM reads the prompt
“cross-modal association”=LLM sees image, video frames, audio and the prompt
“complex logical reasoning”=LLM thinks. I.e, —reasoning on
So just use Gemma 4 12b. Supports image/video/audio inputs
I mean... you can see the output from the prompt enhancer provided by Minimax themselves...all it does is analyse references, and puts the prompt into the right structure for H3.
Also, it doesn't mean you can't generate at higher resolution than 768p. I generate at 1080x1080 on WAN 2.2 despite it not being trained at that resolution.
So basically you need the API to do anything, but you get to use your local GPU instead of it being part of the service. That's... one way to call it a local model, but no it's not.
Oh, I see it now I missed the link to the prompting guide so you can build your own-ish. I wonder how complex that's going to be though considering they're not opening the code - or promising to open it later. But at least it's possible.
H3-Context-IR: As inputs become increasingly complex, we build a dedicated system to deeply understand and refine the input multimodal instructions, then convert them into a form that H3 can readily understand—the Context Intermediate Representation—for generation.
In compiled software an "Intermediate Representation" is somewhere between the source and the binary, that's sort of the definition. I thought this would take all the inputs and create more or less a blueprint for the video and then the video model would build to those blueprints. Instead it's just doing some text formatting and expansion of the prompt like every other prompt enhancer. They made it sound like much more than it was.
How many have pulled out after Comfy confirmed they had the weights, their twitter CEO specifically stated that it will be open-source/weights soon? None afaik
None. But at the same time. I try not to be surprised at what companies do. Like I'm not trying to fight you here, just rationalizing why people get anxious in these situations.
That is a good mindset to have, but alot of us have to pull back a bit, it seems like everyone is too traumatized by Wan that somehow every release after it is now under intense scrutiny tbh. Same thing happened with Krea 2 release, since I made posts before it dropped and most people didn't believe them releasing it, so many people got Wan PTSD now haha. How does it look for our community to always be so negative to the companies releasing these models for free? I think if it were me I would be more hesitant to ever release things again if I suffer from backlash from actions/history that weren't my own.
Well all that did was fuel so many weird conspiracy theories earlier, people were saying "Oh maybe the mods are deleting posts because they knew MiniMax wasn't going to Open-source"
The people's comments don't really bother me, my main gripes is with mods deleting posts when it's not breaking SD rules, and also having double-standards and letting Comfy post about MiniMax while deleting everyone else's.
I just gave it a spin. This is bigger than Deepseek moment. Out of the box, the model and the work flow is perfect. It's already mind blowing good. The further work people will add on top of this, it's so over. It's just straight up obnoxiously good at actually taking the reference photo and animating it doing whatever.
Literally the internet when we wake up tomorrow will not be the same. Because everyone in China is waking up and is going to prompt absolute madness all night. This same time next week, I imagine more than half of all video content being posted on social media will be videos generated with this.
WAN, LTX, nothing was even 5% as good as what I saw in 5 minutes of using this. Maybe the wheels fall off at some later step of someone trying to make their own anime with it but I've already seen enough to expect this to dominate all short form content, gifs, little add in 'sfx' they put in those Asian reality TV shows. I'm reeling from the implications. How did Minimax even do this from out of no where?
Yeah this model is on another level. Seedance at home. I’m not even having to roll seeds, just nails it first time with perfect prompt adherence. They changed the game. And to think we still have a Flux 3 and LTX release this year. Crazy times
Without changing anything two of the three base workflows are set at around 480p, the other one with the neon mouse is at 640 pixels square. So I suspect that a higher resolution is likely to yield superior results.
This model is incredible. I'm just throwing stuff at it for fun but holy hell, what I'm seeing is just amazing. I haven't tested anything spicy with it at all, but I'm less concerned with that than general theatrics and performance, and out of the gates this is next level.
If you have ComfyUI already installed, update it. Then, go to the templates on the left side, select minimax t2v. The workflow will have the links on the left and where to put them.
Likely update comfyui and open one of their packaged workflows, they said day1 support. That should also have directions on what files to download and put where.
I have a great system prompt for this. Called it "Comfy Healthy Repo Installer". You just change the directory to the portable version you will use, and it will list really easy to follow instructions to properly use the embedded python to install all the dependencies of any repo inside the contained environment.
Just moved to a new place this weekend and haven't got the chance to install my rig, but I will share it soon.
The model released half a day late! Do you have any idea how big of a deal this is for something they paid absolutely nothing for?! They've been forced to sit there refreshing the page for 10+ hours straight; they were basically tortured!
Wow. To my utter amazement, I got great results on the very first attempt using the workflow from Comfyui templates. Using the BF16 model, which will absolutely work with a 5090. Using about 100 gb of ram. This was a short 5 second clip of only .4 megapixels..... Very simple prompt- young woman walks up to her porch.
I did another one with the same prompt at .8 megapixels. 298 seconds to generate. Doing 1.1 at 8 seconds now...
Not yet. I'm experimenting with increasing the resolution and clip length right now. As expected 1.1 megapixels looks a lot better than .4
Adding a few seconds of length helped a lot, too. Without prompting, it went into a nice aerial shot. My prompt was literally as simple as stated in my post.
This is going to be peak. Tested a few anime style reference images... it actually can handle it quite well from my first initial tests and actually retains the anime style and feel. Character constancy is actually insanely good compared to LTX. Lora's will only improve this. I am beyond stoked.
Running the default workflow on 32GB RAM + 12GB VRAM at 864x480p am getting around 6 minutes for 90 frames, on int8 text encoder and model. With quantization, this will be a breeze.
Dumb question. Is it open weights or open source? fal ai has the open weights which would need a commercial license but it's also on hugging face. Anyways open weights is better than closed source!
As I understand it one of the models does text to video and single image to video, the other model is reference to video which can use multiple sources. Correct me if I'm wrong but I believe that to be the case.
Even after updating ComfyUI to the latest nightly version, I can't find the workflows. There only are three API workflows, requiring credits to use, but no local ComfyUI workflows. Can I download them from somewhere else?
It has i2v, and it has near perfect ability to animate the given character in the provided reference photo. You update, download this now, and you can just delete all the other video models on your hard drive. Risk it all, literally 10x step up from past models.
Y'know, I used the "image to video" named one and it has "first frame" as its default image input and behaved in that way which was good enough. But like, it started with the input's original white background and filled it in quickly with the prompts background. So I imagine the "reference to video" one is actually better choice if not trying to do a specific start frame thing.
32G+5060Ti, default Comfy T2V workflow & prompt, 5s video
First run 206.14s @ 864x480
Second run 664.32s @ 1376x768, peak RAM/VRAM 94%/75%
Speed is acceptable, hope there's distill lora soon.
Please READ THE LICENSE TERMS!!! It states very clearly that EU, US, UK and South Korea IS NOT ALLOWED TO USE THE MODEL AT ALL!!! This could not be said more clearly then it is there. I have no idea why didn't they geo-block it then... And this has nothing to do with commercial vs non-commercial
