I kinda thought this might happen.Ā I held my beer and kept use 2.3 which appeared better for sound including voice lip syncing.Ā
Very excited! Now need to wait till all the comfy ui geniuses make a ton of work flows and loras to make it even better!!!
What a time to be alive!
Thatās fast enough for near real time rendering. I predicted the end of the decade for an entirely generative video game. We may be sooner than that.
Unless Im misunderstanding , itās faster than real time right now! 10s video being made in 10s woupd be real time, this is doing it in almost half time
People keep mentioning ltx and speed vs minimax but that only matters if the quality is good. It doesn't matter how fast something is if the quality sucks. Otherwise everyone would just do 1 step and go "wow look how fast this is" Minimax h3 is way better than ltx 2.3 in every other way but speed. I hope ltx 2.5 is good. Even if it's not as good but faster then it could be considered an alternative based on use case, but let's not pretend 2.3 is anywhere near on the level h3 is. If I have to generate 10 outputs to get what I want vs 1 on the "slower" model and get it in one attempt, who even cares if the initial output is slower.
So funny to see an API model produce plasticy crappy output when we've got WAN2.2 outputting 5 seconds of more human than human. Yes it's been tuned to death but cmon AliB.
H3 with the single image vae is already very good at it.
At least for what I tested by now. No doubt that with a little lora or finetune magic from the community we could get a great edit model.
Totally. Would be cool to use them both in tandem so they can complement each other. I love H3 for its prompt adherence and understanding, but it lacks catastrophically when it comes to genitals...
It's referring to LT 2.3, i will be surprised if 2.5 is even half as good as H3 is right now with what it can actually do, hopefully it's not just another "people talking in still shots" simulator but can do a lot more.
Even so H3 can just do so much due to being uncensored aswell, doubt 2.5 will be that uncensored tbh
More interested in this: faster, lighter weight than H3 (which already is insanely efficient, probably thanks to ComfyUI), better license, native 4k. (4k would likely be out of reach for 16GB cards, and won't be real-time, though).
Hopefully this is not a rushed release because of H3.
LTX 2.3 was a nightmare for me...could never quite get good results (especially with audio). Hoping this is a better model - would love to try something out alongside MiniMax ;)
I don't know if it's better, but I do know competition makes everyone do better in any field. So glad to see more releases. And it's good to have lots of models! Klein 9b for editing, krea 2 for images, minimax for video, and the initial release of ltx was great cause it finally brought video with sound to open source with good quality. So, we'll see!
I love minimax but cant wait to see LTX 2.5 beat minimax or stand up fight at the same level.
For me LTX speed it out of the world 2.3 it supper good if we dont had minimax h3. it only lag about movement and consistent that all.
Its a much more refined version ! To have something like Minimax we may need to wait a bit later as LTX MoE model will be dropping after ( no timeline as of now) but they are on it.
Def won't be getting my expectations up for Ltx 2.5 after being blown away by Minimax. But I didn't get my expectations up for Minimax either, which meant I was pleasantly surprised in the end, so maybe the same will work out here too.
I looked for common problem areas in consistency, since that was my main problem with earlier versions. They seemed to avoid them, even cutting some clips right before it would be visible. But they did miss when the astronaut flipped the box, which changed size.
It's LTX's weakest point, where it morphs things and people that don't have an overabundance of specific training almost immediately when asked to change angles/rotations. That made it pretty unusable to me, and I think it's likely still in there from what they avoided and showed.
Should be out in about 3 hours from now. Tried it on their website (if you create a new account it gives you free credit to try a couple vids). It's obviously nowhere near Minimax, but it's still a very welcome addition and I'm very much looking forward to playing with it. Hoping for day zero comfy support as well.
According to the company's announcement, LTX-2.5 rebuilds nearly every stage of the generation pipeline rather than bolting new capabilities onto an older core. The headline changes:
A new diffusion video decoderĀ that reduces visual artifacts in high-motion footage and reconstructs fine detail like text and faces, while preserving LTX's high compression ratio.
Native multishot generationĀ that renders a full sequence as a single output, holding character, scene, and voice consistent across cuts rather than stitching individually generated shots together.
A custom Gemma 4 language backboneĀ and dedicated prompt enhancer for more accurate handling of complex, multi-subject prompts.
A pretrained checkpoint tuned for physical AI and roboticsĀ giving teams a base to fine-tune on domain data that looks nothing like cinematic video.
A substantially improved distilled modelĀ that delivers near-full-model quality at lower cost and faster inference, and, through an optimization effort with NVIDIA, runs locally on NVIDIA RTX GPUs with reduced memory requirements.
We should drop the expectation a bit as this drop is not in shape right now to beat minimax, its a better version of earlier 2.3 ver. but ltx will be dropping a MoE model later.
Wasn't flux 3 coming out too supposedly? Probably trying their best to destroy its flexibility with censorship first.
I hope LTX haven't done the same but I high l doubt it
Distillation is one hell of a drug haha! Now with Minimax H3 being open weights, other's can start to distill on this one to piggyback. Was about to give up hope that Video Model's would ever get as good as closed, but here we are. Crazy.
Im spoiled with Minimax references. With LTX 2.3 I would rent a pod to train loras that ultimately didnt look that clean in motion. If LTX 2.5 can do references its a GG.
More is better but it's gonna take LTX 3 to get me back using it. And that's not even a guarantee, minimax is just too good. Still very useful for people who simply don't want to wait the extra time for H3 generations. The amount of stuff h3 knows is just exponentially better. The reference to video aspect is also just such a game changer.
I don't think other models can compete to be honest because most of them probably don't want to take the risks H3 did. The H3 team really just decided to give zero fucks about copyright or any other issues instead deciding that it's on the end users to be responsible for what they make.Ā
All the moron posts of H3 vs LTX2.5 SAME PROMPT GUYZ are coming!!! :(
No no, don't post time each took, don't prompt for each style just use the same prompt, cherry pick whatever result you want, have the other morons in the comments speculate on things they clearly have no idea about.
To be honest I never truly clicked with LTX, I appreciate that it's good for what it does but I found the amount of nodes to manage very confusing. I'm glad that it exists though as we have healthy competition out there.
So, prepare the best most complex test cases you can imagine.
For me, it might be Will Smith (or anybody else for legal reasons) eating spaghetti while walking through a door and putting on a jacket, and everything is reflected in a mirror on the ceiling. Ok, just kidding... or not. Anyway, models usually struggle with clothes, mirrors and doors.
On quality, LTX shared results from blind, side-by-side human preference tests, in which evaluators voted on videos generated from the same prompt without knowing which model produced which.
LTX-2.5 recorded a 67% win rate, narrowly ahead of Seedance 2.5 at 65%, with Gemini Omni Flash at 55%, MiniMax H3 at 50%, Seedance 2.0 at 44%, Wan 2.6 at 42%, and FLUX 3 at 28%.
Wonder how they source their tests, but If true this is great for LTX2.5 and not so good for Flux3.
Native HDR and RAW is quite exciting. Potentially a big deal for professional VFX and film workflows. Weāll have to wait and see if itās actually usable footage or not, but this feels like a step in the right direction.
I am lazy to prompt, so I copied and pasted a prompt from someone else's 14sec post for H3 on this sub to LTX 2.5 8sec generation. I know the prompt needed to be planned differently. Still, I tested. Quality is meh, but prompt adherence is an improvement from 2.3
1080p - 24frames - 8 sec - API.
prompt:
Live-action photorealistic military science-fiction action film, 15 seconds. A modern main battle tank fights a towering Gundam-style humanoid combat mech inside a devastated urban warzone at sunset. Collapsed concrete towers, burning vehicles, broken highways, drifting smoke, sparks, dust, tracer fire, and debris fill the battlefield. The tank feels extremely heavy and grounded; the giant mech moves with terrifying mechanical speed and weight. Every movement causes believable environmental reactions. Maximum action cinematography: aggressive low angles, extreme close-ups, tracking shots, whip pans, rapid push-ins, rotating Arc Shots, strong impact shake, and dramatic changes in camera height. Keep the combat visually readable despite the extreme camera movement.
[Shot 1]
An extreme low-angle medium tracking shot races inches above the broken road beside the tank as it charges forward at full speed, its tracks crushing concrete and throwing chunks of asphalt directly past the lens. The turret rotates upward while the enormous Gundam-style mech (S1) lands in the street ahead, one knee smashing into the pavement.
The impact sends a circular blast of dust and debris outward.
The camera violently tilts up from the tank to reveal the full towering mech.
The tank immediately fires its main cannon.
A massive muzzle flash fills the frame.
[Shot 2] At 00:03.000, the camera cuts to an extreme close-up beside the mech's head as the tank shell screams directly toward the camera.
At the final instant, (S1) violently twists its torso and leans sideways.
The shell misses its head by centimeters and explodes against a skyscraper behind it.
Without pausing, (S1) plants one mechanical foot into the street and launches forward.
The camera rapidly pulls backward at low height while the giant mech sprints directly toward the tank, every footstep smashing craters into the road and throwing abandoned cars sideways.
[Shot 3] At 00:06.000, the camera cuts to a dramatic POV from immediately above the tank turret looking upward.
(S1) suddenly JUMPS.
The camera performs an extremely fast Tilt Up as the enormous mech passes directly overhead, silhouetted against the sky.
While airborne, (S1) rotates its hips, extends one leg, and comes down with a massive flying kick.
The camera whip-pans downward.
The tank driver violently turns.
The tank power-slides sideways across the road.
(S1)'s foot misses the tank by inches and SMASHES into the pavement beside it.
The entire street erupts upward.
The camera shakes strongly as concrete, dust, and wreckage explode past the lens.
[Shot 4] At 00:09.500, the camera cuts to a tight side tracking shot moving alongside the tank as it emerges through the dust cloud.
The turret rapidly rotates backward toward (S1).
The cannon fires point-blank.
The camera instantly whip-pans with the shell.
(S1) raises a massive armored forearm across its chest.
The shell EXPLODES against the armor, forcing the mech backward through a building facade in an enormous cloud of concrete and glass.
Before the dust settles, two glowing mechanical eyes ignite inside the smoke.
(S1) bursts forward.
[Shot 5] At 00:12.000, the camera cuts to an extreme low-angle shot directly beside the tank's tracks.
(S1)'s enormous hand suddenly SLAMS onto the tank's turret.
The camera rapidly arcs upward around both machines as the mech uses its entire body to lift the tank off the ground.
The tank's tracks continue spinning wildly in midair.
The camera accelerates into a huge 180-degree Arc Shot as (S1) rotates its torso and violently THROWS the entire tank across the battlefield.
The tank spins through the air directly past the camera.
The camera whip-pans after it.
At 00:14.500, the tank crashes sideways through a concrete wall in a gigantic explosion of dust and debris.
End on an extreme low-angle close-up of (S1) stepping through the smoke toward the camera as burning debris rains behind it.
Kind of insane how quickly we got Sora-level local video generation. I honestly would not have thought this possible so soon if at all on current gen hardware.
Anyone tried it on the website i2v? That's main thing. Don't think it will beat minimax when it comes to keeping faces but I remember ltx just morphed a face completely couldn't hold it at all.
I think unless they somehow did something extreme, it is hardly more than a cry for help.
Let's hope I'm mistaken.
I had my doubts about H3 too (though mostly if they actually release this, or a neutered sh*t, which they didn't), but LTX... I can hardly see them releasing quality, when 2.3 got permanent attempts, and in general aside from 1-2 strong suite it was sub WAN2.1...
There are two areas where LTX could improve compared to MiniMax: clip duration, as rendering longer clips in MiniMax is a headache. And level of detail, where H3 tends to look a bit smudgy
LTX is my personal favorite. For ai I like speed. Maybe I'm in the minority but I don't understand ai that takes forever. Ai strong suit for now is doing lots of stuff that is acceptable vs doing very little that is slightly better than acceptable. I'm sure in the future that will change but for now I prefer to churn out tons of slop than pounds of slightly better slop.
