Enter the world of LoRA models.

What Are LoRA Models?

LoRA stands for Low-Rank Adaptation, a cool technology that makes it easier to train Stable Diffusion on different concepts, such as characters or styles. In simpler terms, it lets you fine-tune your AI-generated art, making it more vibrant and alive. LoRA models are small, resulting in a reduced file size that's perfect for users with extensive collections.

  • LoRA models come in a variety of flavors, each suited to different tasks.

  • Character LoRA specializes in creating specific characters like popular video game or anime personas.

  • Style LoRA is all about mimicking artistic styles, letting you create pieces that mirror the signature style of a certain artist.

  • Concept LoRA is the Picasso of the bunch, great at conceptualizing specific ideas that are tough to achieve with just prompt engineering.

  • Pose LoRA lets your characters strike a pose, perfect for dynamic scenes.

  • Clothing LoRA is your AI fashion designer, adept at changing your characters' attire, while ...

  • Object LoRA is a whizz at generating objects like furniture or vehicles.

Where Can You Find LoRA Models?

Open-source repositories like Civitai and Hugging Face host a plethora of LoRA models. They are small, easy to download, and absolutely free.

These repositories offer a user-friendly interface and comprehensive documentation, making it straightforward for both beginners and experienced users to navigate and understand the available models.

Additionally, due to their open-source nature, they foster an active community of developers and users, allowing for continuous model improvements, feedback, and troubleshooting help.

How Do You Install and Use LoRA Models?

First, you'll need to install the LoRA extension into your Automatic1111 web UI. Next, you install your chosen LoRA models into the correct folder. Assuming, your A1111 is installed in /workspace/sd, you'd place the LoRA model in:


To use the Lora, you need to reference it in your prompt in the following way:


Here, you'll replace:

  • TRIGGER_WORDS with the trigger words associated with the Lora

  • PROMPT with the details of your prompt

  • MODEL_NAME with the filename of your lora without the extension

  • WEIGHT with the weight you want the lora to have with the output.

Here's an example:

3dmm style,(masterpiece, top quality, best quality, official art, beautiful and aesthetic:1.2), (fractal art:1.3), 1girl, beautiful, high detailed, purple hair with a hint of pink, pink eyes, dark lighting, serious face, looking the sky, sky, medium shot, black sweater, jewelry <lora:revAnimated_v122:1.2>

In this example the trigger word is "3dmm" and the model name is "revAnimated_v122"

That's it, your image is LoRA-enhanced.
