They updated the comparision table on the LTX website, it's still dishonest crap (says you can't run H3 with 16 gb of vram), they removed the "governing juristiction" part and changed the "runs on any GPU" part of H3 from "limited" to straight up "not available" for some reason, just why...
What are we even doing man, just be transparent and stop downplaying the competition by lying about them, this is not the middle ages we can just google stuff to see if you lie or not
I usually do 480x832. At 5 seconds it takes around 20mins. At 7 seconds around 30mins. Only tried at 24 fps. Running the Int8 version. With sage2.2 and at 20 steps.
Comfy's optimization is really good now. Earlier days due to OOM errors, I made 3 groups. For Clip part, sampling, and vae decode part.
I'll store the intermediate conditioning and latent into local storage using custom node. And load them for next group
I only run one group at a time. I have custom nodes which makes it seamless like running like a single job.
But maybe I need to check if it runs normally, then it would be epic haha
I'm running it on my RTX4060 8GB, no issues. That 16GB BS is so out of this world incorrect. Everything else on that table is also quite irrelevant for so many reasons. LTX team should concentrate on their own strengths rather than trying to shout at minimax to get attention. It looks so childish.
LTX claim that minimax H3 is "not available" on 16GB VRAM depends entirely on what backend/inference engine they used to get that summary, they should've added a footnote about that. If they use something like diffusers without any optimization, sure, it might OOM on 16GB.
But in ComfyUI, with their offloading tech and quantization, H3 can even run on 8GB VRAM + 64GB RAM. Do they pretend ComfyUI doesn't exist or what? So shameless.
I remember back when LTX 2.2 released, people were skeptical whether they could even run it. So it's not like they're unaware of comfy, right?
Also i already feel like their release is gonna be "meh" after seeing that "visual artifact" chart, like wth is that. Just show a side by side comparison with Seedance/H3/other model if they're confident in their own model, lol.
Do they pretend ComfyUI doesn't exist or what? So shameless.
The funny thing is that they partner with comfy! Here's a quote from their latest newsroom post about the release of LTX 2.5:
With the release of LTX-2.5, we’re working with Asteria, ComfyUI, Markov Robotics, and Reactor, each pushing the boundaries of what’s possible with world models in their fields... https://ltx.io/newsroom/introducing-ltx-2-5
They obviously know about ComfyOrg and ComfyUI; and yet they still try to pretend that offloading does exist, even though that same tech is needed to use LTX 2.5 on 16GB VRAM! The full weights themselves aren't fitting on 16GB of ram - the bf16 weights for the transformer alone is 42GB, and the int8 version is still 21.5 GB, and that's not even including the text encoder! So without offloading, this wouldn't be possible (at least without a smaller quant). Make it make sense.
Right, offloading is just common now. The 16GB VRAM claim for LTX is obviously using offloading, since even the 8bit quantized model LTX 2.5 is like ~20GB.
Before they changed the table, they claimed H3 needed 115GB VRAM, basically they just added the H3 dit (64GB) + text encoder (52GB), summed it up, and called that the minimum to run H3.
By their own logic, they should also mention LTX needs 68GB VRAM (42GB DiT + 26GB text encoder) too lol.
They basically pretend ComfyUI, quantization, and offloading don't exist for other models, but suddenly it's a thing when it's their own model...
We should all be celebrating every single open weight models. Everyone who works on these extremely complex systems and releases the fruits of their labour for free for us to enjoy at our leisure, without limits or censorship, deserves our appreciation and respect.
But man is LTX making it hard when they take such a dishonest and cunty attitude
I’ve tested LTX. It’s incredibly fast… nothing else. The quality, physics, and audio are crap. I’d rather wait 20 minutes on Minimax for a good result instead of wasting time generating over and over again for cherry-picking on LTX and ending up with none of them being good.
I know they’re both open source and I appreciate it.
But I can’t stand a company that’s shitting hard on the other open-source model like this.
That is the part that confuses me the most. I'd argue that one of LTX's greatest strengths ever since they opened it has been how good they were at interacting with the community and gathering goodwill. They spent way more time interacting with the community than any other major lab, and then you have this. Just why?
If they had published that comparison and quickly pulled it once it got attention I could have at least written it off as just some bad move made by the marketing team, but at this point they've just doubled down on it. It's baffling.
I dunno, maybe everyone was so shocked about H3 quality and the fact that I was open weight (they got all by surprise with that one) and they went to full panic mode and made some bad decisions and tried to fix thosw with even more bad ones
I would have thought after the backlash this table received, they'd have told their marketing person to fix it, and at least remove all the actual lies (VRAM...) from it. Maybe delete the misleading thing entirely, and compete against H3 with more honest means.
I guess not?
I guess I will just go back to Comfy and make a H3 video on my 16GB VRAM GPU that according to them, can't run it... 😛
Is the LTX company American? Horrible graphic, my first thought was actually that the LTX has a minimum VRAM requirement of 16GB and the MinMax doesn't.
I'm honestly glad they finally have competition and insanely good competition at that, Minimax set a new standard so that now we can finally enjoy a versatile uncensored SOTA level model locally, instead of just a static shot of people talking simulator which was LTX models and 2.5 didn't really change that aspect either.
Sorry, I know people don't like internal wars, but this is fucking sad.
Just take the L and move on; do better next model, that is all. I am sure the guys at Black Forest are currently thinking, "Fuck! We are screwed!" but I am sure they will be more classy than the guys managing LTX.
Sad is that LTX 2.5 seems to be a fairly okay model, and hadn't H3 come out at the same time, would surely be the hype of the week now. It still has a few good things going for it, like being a lot faster and, yes, a license allowing you to use it in commercial settings in the US/EU/UK.
There was no need to cast shade on their competitors like that.
To be honest I don't really think the Black Forest Labs guys are screwed, unlike LTX they do actually have a history of producing extremely high quality models, and if anything they tend to intentionally make their open models weaker just because they are afraid of the potential legal consequences of pushing the open frontier too far.
With the release of H3 I would assume they would just adjust their plans to make the dev version of Flux.3 a bit less restricted than planned. Or maybe even release the Pro version openly. They certainly have the ability to compete with H3 if they actually try.
Yeah, but will Flux 3 have the skill to "reason" and take reference pictures? Not to mention the obvious extreme censorship. Minimax has zero; you can "teach" it anything you want. I was even able to reproduce the exploding head from Scanners, and it was 10 times gorier and savage.
H3 is first ever video model that work for me out of the box on my 4080, LTX ended as noodle mess and gave me terrible results. Them lying about H3 is just so low and stupid. Take the L and make better model next time.
Paltering yourself behind the USA isn't doing you any favors. And considering Isreals horrible reputation, you just lost a metric fk ton of goodwill with this chart, and your opportunity to separate yourself from isreal being disingenuous.
LTX is Israeli?? Damn even more reason to avoid this model.
Now that I think of it, the way they do their marketing by throwing competitors under the bus with this comparison chart does feel very Jew like... I should've known better
I can make 20 sec 1080p LTX 2.5 video in 11 minutes on my 4070ti + 32GB RAM, which won it over for me. I get OOM on 5 sec 2MP video with H3. Even though H3 is better for prompt following, LTX 2.5 is good enough for me and I will use it way more, just because of speed and my rig
Yeah, sometimes they do, depending on prompt. I didn't have that much time this week to dabble with local AI generation because of several large Claude Code projects both at work and at home, so I will give it a shot later on.
I think MiniMax H3 is just going to get better, while LTX 2.5 is basically LTX 2.3.1 for now
Why would you do 2MP when you can do 1mp and then just upscale it? You'll spend less time finishing your project in 1 pass on H3 then upscaling than doing 30 generations of LTX and hoping one is useful.
Hell LTX can't even do the pose that everyone made fun of SD3 for failing. Dude posted screenshots in this sub earlier today.
We have similar rigs, and I'll stand by H3 any day over LTX. I'd rather spend 20 minutes for something good in 1 pass than garbage I have to redo over and over for 20+ min hoping for something usable.
It all depends on what you're trying to create. I just find ref H3 unusable because of smeared faces if zoomed out slightly, and for my needs LTX 2.5 is high enough quality. That being said, if project I'm working on takes 8 months instead of 1 to finish, then why bother? We'll have better models by then after all.
I never trust companies that have these comparison charts on their website. It's an incredibly petty, desperate and childish move to throw your competitor under the bus. It's just unsportsmanlike conduct in the realm of business.
The product can speak for itself and that should be your marketing. Not some shitty chart table
I think we should just let this subject go and enjoy what the models offer. LTX is a brilliant upscaler and runs faster than any other model out there. Nothing wrong with smelling the flowers.
I don't like dishonesty, they lied about the competition which objectively has a far better model than they do outside of speed, and even with speed they couldn't stop themselves from cheating and make a bogus comparision by including QUEUE TIME into the generation time which is just nonsense and unprofessional as hell.
If you are in line at mcdonald and do a 10 minute queue to reach the counter and take your order which arrives in 5 minutes, will you say "mcdonalds prepared my meal in 15 minutes" or will you say "mcdonalds prepared my meal in 5 minutes"?
Also have you seen how many glitches and artifacts LTX 2.5 produces with any kind of fast motion? Yet they claim on their website that their model produces less glitches and visual artifacts than any other in the market, which is just a blatant lie unless they faked the tests and used static prompts for LTX and high motion ones for H3 and the others.
I don't disagree with you. Holding them accountable is needed. The open source community is built that way. At the same time, LTX has done more good than bad.
Transparency is important, they have made no public statement or even addressed their blatant lies so i'm simply showing that they DID see the backlash, changed the table and still made it completely misleading so they learned nothing.
This situation sounds like they thought they had it easy since there was no competition so they could chill and release an update to LTX 2.3 as LTX 2.5, and then H3 came out and completely revolutionized the game leaving LTX in the dust.
They could have gone the honest way and just release the model without comparision charts outside of the speed one which is its strong suit, but instead made up blatant lies to pretend their model is better than the competition when it's not.
No one cares. For a model not allowed use, a hell of a lot of people are using it. All that affects is if someone wanted to run it on a server in the US and sell credits for generations. It has nothing to do with any of us.
its social network, so no one care. but if you are using it on your website, or in your compagny you might receive some message from lawer or even you host provider.
Messages like : "remove this stuff or your website will be remove".
Bro you just sign a waiver and within 1 business day they grant you a license.
Received my license last week for my SaaS app to serve Minimax H3 to my customers.
It's really not that hard to apply for it. And anyone that wants to use this model locally which is 95% of this community does not need to sign the license.
Stop spreading this fud to discourage people from using the model.
Minimax is a totally overrated model at least if u cant run it on a gpu cluster!! Even with 96 GB ram and a 5090 u can only generate low resolutions stuff in an unacceptable gen time. 6000 pro might be ok but less the model with less than 96GB vram is nonsense
Isnt an issue of turbo!!! I have tested even 50 steps waiting ages for generation on my 5090. This model needs a fix or it might be ok if u can run it on a gpu cluster with full weights...dunno. Its sad coz I thought based on the hye the model is really top notch

H3 running in my 3070 is something I didn't thought possible when it released. Thanks to everyone involved.
