TurboDiffusion: 100–200× Acceleration for Video Diffusion Models
- jjcm 10mo agoLooks like there is some quality reduction, but nonetheless 2s to generate a 5s video on a 5090 for WAN 2.1 is absolutely crazy. Excited to see more optimizations like this moving into 2026.
- villgax 10mo agoThat’s not the actual time if you run it, encoding and decoding is extra
- Lerc 10mo agoNevertheless it does seem that generating will fairly soon become fast enough to extend a video clip in realtime. Autoregressive by the second. Integrated with a multi modal input model you would be very close to an AI avatar that would be extremely compelling.
- avaer 10mo agoEfficient realtime video diffusion will revolutionize the way people use computers even more so than LLMs. I actually think we are already there with quality, but nobody is going to wait 10 minutes to do a task with video that takes 2 seconds with text. If Sora/Kling/whatever ran cool locally 24/7 at 60FPS, would anyone ever build a UI? Or a (traditional) OS? I think it's worth watching the scaling graph.
- IsTom 10mo ago> If Sora/Kling/whatever ran cool locally 24/7 at 60FPS, would anyone ever build a UI? I like my buttons to stay where I left them.
- pavlov 10mo agoYeah, it’s like asking “why would anyone read a book today when LLMs can generate infinite streams of text”
- exe34 10mo agothose streams of text are often conditioned on the prompts - people are using it to learn about new concepts, and as a hyperpersonalised version of search. it can not only tell you of tools you didn't know existed, but it can show you how to use them. I do like my buttons to stay where I left them - but that can be conditioned. instead of gnome "designers" telling me the button needs to be wide enough to hit with my left foot, I could tell the system I want this button to be small and in that corner - and add it to my prompt.
- pavlov 10mo agoI suppose if one only reads self-help books of the “You’re the best, trust your instincts!” kind, then LLMs are an appropriate replacement.
- exe34 10mo agoOr indeed, if one has a mind of their own and wants a tool to obey them, rather than submit to their "betters"'s opinions.
- pylotlight 10mo agoI feel like a lot of the above assumes the user knows what they want or what works best. I want an intelligent designer to figure out the best flow/story/narrative/game and create/present it, cause I'm a dumb user who doesn't know what is actually good.
- exe34 10mo agothat's called a default - I'm happy for a gnome designer to "design" the button to be large enough to hit with my foot with a blindfold on, but I'd like the option to change it to adjust to my workflow rather than adjust my workflow to the button.

- subscribed 10mo agoPlease no, please no That will be Windows 12 and perhaps 2 generations in of iOS :)
- villgax 10mo agoI mean the baselines were deliberately worse and not how someone would be using these to begin with maybe noobs and the quoted number is only for DIT steps not for other encoding and decoding steps, which is actually quite high still. No actual use of FA4/Cutlass based kernels nor TRT at any point.
- redundantly 10mo agoNow if someone could release an optimization like this for the M4 Max I would be so happy. Last time I tried generating a video it was something like an hour for a 480p 5-second clip.
- deleted 10mo ago[deleted]
- jimmydoe 10mo agomaybe wait for M5 Max and new MLX.
- mishu2 10mo agoHaving the ability to do real-time video generation on a single workstation GPU is mind blowing. I'm currently hosting a video generation website, also on a single GPU (with a queue), which is also something I didn't even think possible a few years ago (my show HN from earlier today, coincidentally: https://news.ycombinator.com/item?id=46388819 https://news.ycombinator.com/item?id=46388819). Interesting times.
- iberator 10mo agoComputer games have been doing it for decades already.
- nkmnz 10mo agoBob Ross did it, too.
- pwython 10mo ago1 frame of Bob Ross = 1,800s
- ash_091 10mo agoSo with 108,000 (60 X 1,800) Bob Ross PPUs (parallel painting units) we should be able to achieve a stable 60FPS!
- mishu2 10mo agoOnce you set up a pipeline, sure. They'd need a lot of bandwidth to ensure the combined output makes any kind of sense, not unlike the GPU I guess. Otherwise it's similar to the way nine women can make a baby in a month. :)
- justinclift 10mo agoThe food/housing/etc bill for 108k Bob Ross er... PPU's seems like it would be fairly substantial too.
- codingbuddy 10mo agoWe are scarily close to realtime personalization of video which if you agree with this NeurIPS paper [1] may lead to someone inadvertently creating “digital heroin” [1] https://neurips.cc/virtual/2025/loc/san-diego/poster/121952 https://neurips.cc/virtual/2025/loc/san-diego/poster/121952

- hapticmonkey 10mo ago> We further urge the machine learning community to act proactively by establishing robust design guidelines, collaborating with public health experts, and supporting targeted policy measures to ensure responsible and ethical deployment We’ve seen this play out before, when social media first came to prominence. I’m too old and cynical to believe anything will happen. But I really don’t know what to do about it at a person level. Even if I refuse to engage in this content, and am able to identify it, and keep my family away from it…it feels like a critical mass of people in my community/city/country are going to be engaging with it. It feels hopeless.
- casey2 10mo agoYou just fell outrage bait so I doubt you will be able to identify AI.
- rvnx 10mo agoI tend to think that it leads to censorship, and then censorship at a broader level in the name of protecting our kids. See with social networks where you now have to give your ID card to protect kids. The best way in that case is education of the kids / people and automatically flag potentially harmful / disgusting content and let the owner of the device set-up the level of filtering he wants. Like with LLMs they should be somewhat neutral in default mode but they should never refuse a request if user asks. Otherwise the line between technology provider and content moderator is too blurry, and tomorrow SV people are going to abuse of that power (or be coerced by money or politics). At a person / parent level, time limits (like you can do with web filtering device for TikTok), content policy would solve and taking time to spend with the kids as much as possible and to talk to them so they don’t become dumber and dumber due to short videos. But totally opposed that it should be done on public policy level: “now you have right to watch pornography but only after you give ID to prove you are adult” (this is already the case in France for example) It can quickly become: “now to watch / generate controversial content, you have to ID”
- kristopolous 10mo agothis is probably the best tool for this stuff now: https://github.com/deepbeepmeep/Wan2GP https://github.com/deepbeepmeep/Wan2GP It has fastwan ... probably will have this soon. it's a request in multiple tickets: https://github.com/deepbeepmeep/Wan2GP/issues https://github.com/deepbeepmeep/Wan2GP/issues
- bsenftner 10mo agoVideo AI acceleration is tricky, where many of the currently in use acceleration loras and cache level accelerations have a subtle at first impact on the generated video, which renders these accelerations as poison for video work: the AI's become dumber to the degree they can't follow camera directions, and the character performances suffer, the lip sync becomes a lip flap, and the body motions are reduced in quality, and become repetitive. Now, I've not tested TurboDiffusion yet, but I am very actively generating AI video, I probably did a half hour of finished video clips yesterday. There is no test for this issue yet, and for the majority it is yet to be realized as an issue.
- fcpk 10mo agoOut of curiosity, what do you do with the footage? in a personal way I found it fun for the occasional funny situational video, or for some small background animations, but not so useful as a whole. I understand for things like making sketches from scripts and quick prototyping it's nice, but I am genuinely curious what's the use :)
- Atomic_Torrfisk 10mo agoAlso interested, since that is my same impression.
- bsenftner 10mo agoI'm creating a college / corporate seminar level class with a 3D animated host and instructor. Each lesson begins with a brief animated intro, which the student then reads their lesson afterwards, and then there is a chatbot that understands that lesson that engages with the student afterwards. The course will have about an hour of 1-2 minute videos in the end, and because they are an animated "professor" it is then possible to create other ethic versions, and other language versions easier than otherwise. And for the curious, that hour of final in-use video will be sourced out of somewhere around 8 hours of final video; these video AIs are fine and dandy for short content, but when working on longer form media the consistency issues grow to Godzilla sized and really become the most consistent issue: trying to keep the likenesses of the characters, and the environment from drifting over time.
- sroussey 10mo agoI want to use this on a website!
- benreesman 10mo agoFun fact: if you say the right prayers to the Myelin Gods it will fuse straight through sage3 at D/DQ like it's seen it before, which of course it has. https://gist.github.com/b7r6/94f738f4e5d1a67d4632a8fbd18d3473 https://gist.github.com/b7r6/94f738f4e5d1a67d4632a8fbd18d347... Faster than Turbo with no pre-distill.
