Local. Open weights. Native 4K. LTX-2 is now a 100% Open Source AI video model, and I tested it on my rig! Installation, VRAM usage, and the prompts I used for this video, below 👇

The team at @ltx_model didn’t just drop an API, they released the whole system: • Full weights • Training code included • Runs 100% offline Total privacy, no subscriptions, and everything stays on your machine. If you’ve got the GPU, you’ve got the studio.

Why is this huge? • No credits or queues • Total Privacy (Runs offline) • Infinite free iterations Real polish happens when you can refine a shot without worrying about the cost per generation.

Hardware Reqs 🖥️ Good news: You don't need a data center. LTX-2 is optimized for standard NVIDIA RTX consumer cards. They included Distilled and Quantized variants specifically to slash VRAM usage. If you have a modern GPU, you can run this. Let's go with the prompts 👇

For the AI Filmmaking pros, here is the creation process. Source Stills: I used Nano Banana Pro inside LTX Studio to generate a consistent 3x3 grid (storyboard). Here is the prompt I used for the stills.

Then, using the grid as reference, I used this prompt to extract each frame attached you'll find a 3x3 grid, with 3 rows and 3 columns. I want you to extract just the still from ROW X COLUMN Y

Finally, we take those stills and animate them with LTX-2. The capabilities here are wild. We are talking Native 4K output and tightly aligned speech/audio generation. It handles the heavy lifting while keeping the details sharp. Here you are a couple of JSON prompts!

How you going to leave us hanging on VRAM usage? 🤣

🤣🫡

soo good!

thanks Tom!

awesome. Which GPU are using again? Maybe I missed it.

A few years from now, you will have an open source movie studio running on your phone!

I agree 100%

I may have to try this on my 4090 laptop. But, I swear to you, I can roast marshmallows from it - the heat that comes off it. 🤣

hahaha

That is awesome! How about the Apple M1 Pro?

Not sure about that, hey @LTXStudio can you support us here?

@LTXStudio Thanks!

Any chance this runs on a MacBook? I don’t have nvidia. Lol

not sure about that, I'm asking LTX team directly and let you know as soon as I get a response :)

Thank you! I’m hitting a brick wall on a lot of models that just aren’t optimized like 3d models or models like this. and I have a decent m3max 36gb. Lol

yeahh I know it's a pity :/

Not a dev or AI guy, So If I had a movie script, how would I get my script into the story board? Would it take the last frames, this looks like different 6 second chunks spliced together. I'm looking for the charector and scene to be passed to the next 6 second chunk in other words, continuing the narative. Possible or no?

How’s the speed on your rig?

Around 5 mins.

Yeah one of them nvidia machines is definitely going to be on everyone’s list soon. Imagine your own computer doing this at speed !!! We will be the new generation of production

Yeahhhh

Awesome! But my ASUS VivoBook 16X can't handle this, even with the max configuration. I need to build a new desktop rig for it. Thanks for sharing your testing, señor @techhalla... 😊🙏

Anytime mate

That offline full stack open source setup changes what you can prototype at home

100%

I hope it runs on 16GB VRAM

it does, but it will take longer to generate

That is definitely interesting if you have the power to run it

Yuppp

👑

☺️🫂

What about the vram ? How much needed ?

I have 16GB and it worked

nice a must try this weekend

🔥🔥

Coolest time to be alive!!! 😀🙋‍♂️🙏💙

yesssss

Well, I needed an excuse to upgrade my battle station and my bday is coming up 😅

yeah!! now there's no choice, you need that upgrade haha

It sounds powerful!

it is!

What's your preferred approach using LTX?

Now it's the best open source model so I'm using it locally!

I need this in my pc

@Julian_cano_ Comfy Manager latest update, that's what you need!

I need some sauce on comfy Finally good to go but don’t know what else I need.. definitely this

@Julian_cano_ I'm prepping a tutorial for next week

Waiting……🫱🏻‍🫲🏼

This is huge! Wanted to give it a try but just crashed my VM. Seems that 16GB VRAM and 48GB RAM is not enough 😕

It worked for me with 16vram!

Maybe I'm just using the wrong base model. But thanks anyway for your awesome thread! 🫶

I'll share how I installed everything from scratch next week, hope it helps

This really would be helpful. Kudos to you! Have a nice Sunday!

You too!!

Can it run on a Mac?

Nope

What benefits do you see with locally hosted gens?

@MintyFreshVibes long term cheaper and no censorship

@MintyFreshVibes Why would they do that? That doesn't seem like a viable business model to me.

It’s about "Mindshare" over "Market share." By releasing LTX-2, they turn their model into the industry standard while saving millions in cloud costs (since we run it locally). They make money by selling the premium cloud platform (LTX Studio) and commercial licenses to big companies. Think of it as a top-tier lead magnet. btw, this is just an opinion about this kind of business models, I don't have any information about it from LTX or Lightricks

The only open source model with native audio 🚀

What's the best doc on how to install ComfyUI with LTX-2? I've run into a few issues.

I've upgraded my PC yesterday, and had to install Comfy this morning from scratch. Used cursor and this prompt: I need you to install ComfyUI on the latest version, and then install the ComfyUI Manager following this tutorial: If you need me to do anything, just let me know. -- Then I used comfy manager to install LTX-2 and worked at first try :)

Thanks, I’ll give that a try with Copilot from VSCode

oh wow! terrible!

Ai slop looks like dog shit

What’s a recommended rig configuration to run it?

Ooooh very nice mate.

Thanks captain!! 🙏
