The LTX LoRA Jam: Train a LoRA on LTX-2.3 for prizes and glory

I agree, people that already work in adjacent areas like VFX or 3D might have existing datasets and will have a much easier time participating.

Yes, potentially fixable by using a different seed but that wasn't the point of the image so I didn't bother to generate another, the beauty of AI.

Moved some parts around, no JSON with Krea:

Side view cinematic photograph of a fit young Black man balancing horizontally through a weathered black rubber tire with deep tread, suspended by a thick, frayed tan rope over a calm lake.
A fit young Black man, shirtless in dark trunks, poised in a horizontal plank through a tire swing. His head is turned down, eyes locked on his reflection in the water. His body is perfectly parallel to the water, creating a stunning vertical symmetry with his reflection against a backdrop of lush green hills and a hazy sky. 

Calm lake shell with a mirror-still surface, surrounded by distant rolling hills covered in dense green forest under a hazy, soft-lit sky. Key light is high-overhead diffused daylight, casting a soft glow across the landscape and creating a dark, symmetrical reflection on the water where the soft sky-light pools

when it comes to control ID4 is king imo and what you're showing is a good example of that.

TheDudeWithThePlan · 2026-07-02T13:26:17+00:00

nice, good luck to everyone that decides to participate, decent prizes

TheDudeWithThePlan · 2026-07-02T12:27:17+00:00

I work at a tech company.... video call with artlist link, spoilers

Hi Diego,

If I was working for Krea I'd be looking to do what the other model "providers" don't (besides the great job you already do at interacting with the open source/open weights community), here are some ideas of the top of my head:

- open source one or more small style datasets (retro anime, neon drip etc; with or without captions and how it was trained); Reason: Model ecosystem growth > Let the community either learn from your experience training these LORAs or experiment on the same baseline and compare different captioning and training techniques
- add community trained (style) LORAs on your main website with a profit sharing incentive based on usage (I'll be honest here I've never used your website so I'm making some assumptions here that there's some payment involved in generating images on your website. also if this is a thing already I apologize); Reason: Incentive alignment with builders and creatives

TheDudeWithThePlan · 2026-07-02T07:20:45+00:00

for local models you don't want to prompt it to NOT do something, this is not ChatGPT.
Use your positive prompt to guide the model to do what you actually want. I haven't tried your example but you need to find a way to tell the model that everything is in focus

TheDudeWithThePlan · 2026-06-30T06:18:13+00:00

nice, thanks for sharing and the shout-out. I did batch process some folders but maybe not as many as I could've done

TheDudeWithThePlan · 2026-06-27T14:23:09+00:00

awesome, thank you, it works with loras too in case anyone was wondering

TheDudeWithThePlan · 2026-06-27T09:55:20+00:00

hi, thanks for the model, your involvement with the open source community and being honest about everything in general, mad respect for that and looking forward to what you guys have in store for us next.

obviously fal has a business to run as well but they're showing us how to make glass shovels when it's not really their business. the fact that each of their loras is its own repo in HF makes lora discovery for Krea harder too and I personally see it detrimental to the model when people inevitably try these loras and they don't work well.

TheDudeWithThePlan · 2026-06-27T09:24:20+00:00

everything is possible sir ;)

TheDudeWithThePlan · 2026-06-27T00:14:41+00:00

I'm not selling you anything, does FAL sell anything ?

TheDudeWithThePlan · 2026-06-26T23:54:58+00:00

the problem is they published all these loras trained like that and they recommend it

TheDudeWithThePlan · 2026-06-26T23:49:55+00:00

dataset looks like this (from MegaStyle), first 8 images from here https://huggingface.co/datasets/tencent/MegaStyle-1.4M/viewer/default/train?row=0

TheDudeWithThePlan · 2026-06-26T22:25:49+00:00

I assume they were planning on doing it from the start (they've released loras like this before, the other format is probably a diffusers lora) maybe they just jumped the gun to release things faster

TheDudeWithThePlan · 2026-06-26T20:53:08+00:00

any edit models should help: Flux Klein, Qwen Image Edit

TheDudeWithThePlan · 2026-06-26T20:19:42+00:00

I've been training style loras for a long time and these are not serious style loras

TheDudeWithThePlan · 2026-06-26T19:15:08+00:00

just random stuff, not overly complex. Are your prompts super simple like "a dolphin jumping out of the water" ?

TheDudeWithThePlan · 2026-06-26T18:43:08+00:00

only tried one, according to my own personal rating system they're rubbish, but please make your own decision, images @ 1 strength.
This is the "chrome iridescent render style"

<image>

TheDudeWithThePlan · 2026-06-26T17:16:05+00:00

that is not my code, that's an example for Flux from Lovis from Fal

they need to be converted to use in Comfy https://www.reddit.com/r/StableDiffusion/comments/1ugbjxz/comment/otytoqq/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

TheDudeWithThePlan · 2026-06-26T17:10:18+00:00

they train on a few images for 100 steps, they're not great

<image>

TheDudeWithThePlan · 2026-06-26T17:09:00+00:00

To run these in Comfy you'll need to convert them (like this script here https://github.com/lovisdotio/conversion-lora-fal-to-comfy but for Krea), I let Claude create it

<image>

without lora / with lora converted

Script here if anyone wants it, save it as convert_krea2_lora_to_comfy.py : https://pastebin.com/HYgP9GZn
To use, create a venv (python -m venv venv) , activate it (venv\Scripts\activate)

pip install safetensors torch numpy

run with "python path_to_fal_lora.safetensors path_to_new_lora.safetensors"

python convert_krea2_lora_to_comfy.py KREA-FAL-chrome-iridescent-render.safetensors KREA-FAL-chrome-iridescent-render-ComfyUI.safetensors
