LoRA AIWhat it is
A small model file that plugs into a large model and changes only how it understands one character, product or style. The large model itself is never retrained.
Your character. Your style. Your next idea.
Train LoRA models. Generate AI images and videos.
Give AI a memory card: upload photos of one character, product or art style, train a model that is yours alone, then generate images and videos with it. Everything runs in your browser. No downloads, no GPU.
Try:
Quick answer: Prepare a compatible dataset, sign in and review the credit cost to submit image or video LoRA training. Use the paired generator after training; LoRAs from different base models are not interchangeable.

First things first: what is a LoRA?
A base model has seen hundreds of millions of images, but never you, your product or your art style. A LoRA is like a memory card for it: a few to a few dozen images teach it one thing, and from then on your trigger word in a prompt brings that thing back.
Why nothing to download
Training on your own computer usually takes a GPU with 16–24 GB of VRAM plus Python, training scripts and ComfyUI. On LoRA AI, uploading, training and generating all happen in your browser. No GPU, nothing to install.
How to use it
Upload 4–30 images of one subject → click Train → put the trigger word in a prompt to create new images or videos.
How many credits does one training run take?
Fixed credits per training run on LoRA AI. The exact cost is shown again before you submit.
| Model | One run | Best for |
|---|---|---|
| Krea 2 | 100 credits | Your first try; trains from a single image |
| FLUX.1 / Qwen Image | 167 credits | Characters, products and styles |
| Z-Image Turbo | 209 credits | Fast image generation |
| LTX-2 19B | 584 credits | Prompt only, 720p, 5–20 seconds |
| Wan 2.2 I2V | 1,667 credits | Starts from an image, 480p, 5 or 8 seconds |
| FLUX.2 Dev | 2,134 credits | 10 or more source images |
The $29.90 Starter monthly plan includes 1,000 credits: enough to train one Krea 2 LoRA and generate 90 images with it.
4 mistakes first-time trainers make
- Mixing two people or two stylesThe model blends them into something that is neither. Train one character, product or style at a time.
- Same angle, same backgroundThe model learns the background as part of the subject. Vary angles, lighting and scenes.
- Watermarks or text in imagesThey show up in your generations too. Crop them out or swap the image before uploading.
- A common word as the triggerA word like "girl" fights its usual meaning. Use something unique such as ohwx_.

From dataset preparation to LoRA training and generation
Image and video LoRAs train in the cloud: Krea 2, FLUX, Qwen Image, Z-Image and FLUX.2 for images, Wan 2.2 and LTX-2 for video. Generate with your trained model right here when it finishes; MOSS and Anima also generate directly. Credits are shown before you submit.
Train your own image LoRAUpload images, review each caption and train with Krea 2, FLUX, Qwen Image or Z-Image. Then generate with it straight from My LoRAs.Train your own video LoRAUpload 3–10 MP4 clips to train a Wan 2.2 or LTX-2 video LoRA, then generate new videos with the same character, motion or camera style.
Each model needs compatible LoRA weights; adapters are not interchangeable. Resolution options and credit costs appear in the generation workspace.

Online training requires an account, enough credits and a dataset that meets the selected model requirements. You do not need to install training software or configure services on your computer.
Cloud training sends your selected media and captions to the provider. Image and video dataset limits differ. Confirm account readiness before submitting.
A focused workflow
Prepare your dataset, train a LoRA, test new images
Organize training images around a character, visual style or product. Align your dataset, captions, base model and test prompts. Review the material, submit Krea 2 training, then test different scenes and compositions in Generate.
Match your model to the creative goal
Characters, styles and products need different source material. Use Krea 2 for cloud training and each model’s compatible adapters for MOSS or Anima generation.
Inspect the image dataset
Review dimensions and repeated images. Keep useful changes in angle, lighting and background, and check upload limits before submitting cloud training.
Review and edit each caption
Describe changing outfits, poses and backgrounds while keeping the intended character or product concept clear. Check the trigger word before training.
Generate and compare after training
Check results in My LoRAs and generate images with completed weights. Keep prompts and settings for comparing new scenes, alongside an exported dataset draft.
Ideas worth teaching
Character, style and product concepts for LoRA datasets
Explore three ways to define a training concept. Each reference links to a dedicated workflow, with dataset advice and evaluation prompts.
A style that travels.
Use this coastal illustration as a visual-language reference. A style dataset should vary the subject while keeping its materials, colors and mark-making coherent.
Caption exampleA coastal village in ohwx_style, gouache texture, warm flat colors and fine ink contours.
Explore style LoRA training
One character. New settings.
An original ceramic explorer gives a dataset a clear identity. Vary the angle, pose and surroundings instead of repeating one composition.
Caption exampleohwx_robot, a ceramic explorer with blue glass eyes, standing beside an alpine lake in daylight.
Explore character LoRA training
Keep the product recognizable.
A blank amber bottle makes shape and materials easy to discuss. Include alternate views of its glass body and cap rather than teaching a single background.
Caption exampleohwx_bottle, an amber glass bottle with a round walnut cap, on a travertine surface in window light.

From intent to evaluation
How to start a LoRA training run
Prepare the image or video dataset required by the selected model, review its trigger and captions, then submit training. Use the completed weights with their matching generator.

Dataset & compatibility
Prepare a useful dataset for your custom LoRA
Choose the base model before preparing a dataset. Krea 2 training weights belong in a compatible Krea 2 generation workflow. MOSS and Anima require their own adapters; similar model names do not establish compatibility.
Read the dataset preparation note- Choose one concept for the first run.
- Use examples you have the rights to train on.
- Remove corrupted files and unnecessary repeats.
- Keep untouched images separate from exported JSON drafts.

FAQ
LoRA training and AI image generation FAQ
Model-specific guidance, with the current availability stated clearly.
What can I train with LoRA AI, and how do I start?
You can train character, style and product LoRAs. Images: Krea 2, FLUX.1, Qwen Image, Z-Image and FLUX.2 Dev. Video: Wan 2.2 I2V and LTX-2. Open Train, upload your material, review captions and the trigger word, then submit once signed in with enough credits. Progress and finished models live in My LoRAs.
How do I generate after training? Can MOSS or Anima reuse those weights?
When training succeeds, open the paired generator from My LoRAs and include your trigger word in the prompt to create images or videos. A LoRA only works with the model it was trained on; MOSS and Anima also need their own matching LoRAs. Credits are shown before you submit, and preparing material or exporting drafts is free.
Can I submit a paid training job on this page?
Krea 2, FLUX.1, FLUX.2 Dev, Qwen Image, Z-Image, Wan 2.2 I2V and LTX-2 19B have training and paired generation integrations. Paid tasks require configured services, sign-in and sufficient credits. Other catalog models remain previews.
What happens to the images I add?
Local draft preparation processes images in the current browser tab; exported JSON excludes source files. Refreshing or leaving clears local images. Submitting cloud training sends the selected dataset and captions to the provider; WaveSpeed training also uses configured R2 storage for datasets and archived artifacts. Storage privacy depends on bucket access settings. Generation sends prompts and selected LoRA references to the relevant service. Only submit material you have permission to use.
Can I reuse one LoRA with every image or video model?
Adapters are not interchangeable. Match the model architecture, base version and loading workflow. Krea 2, MOSS and Anima need their own compatible weights; similar names do not imply compatibility. Video workflows may also require multiple adapter files.
