What is Civitai?

Civitai is a platform where fine-tuning enthusiasts can effortlessly share their creations and connect with other creators. It is an innovative platform designed to enhance the creation and exploration of ai-generated media. It provides an environment where users can upload, share, and discover custom models trained on various datasets. These models, backed by ai media software, serve as unique tools for generating original content. It gives access to various models trained on checkpoints.

Basic Terminology

1. Model checkpoints: Model checkpoints refer to saving the state of a machine learning model at certain points during training. A checkpoint includes the model's weights, biases, and other parameters that define how it processes data. You can pause and resume training later by saving checkpoints or use these saved states (checkpoints) for inference. On platforms like Civitai, users can download these checkpoints to generate content or continue tuning models.
2. Base models:Base models are pre-trained machine learning models that are the starting point for further fine-tuning. These models have been trained on large datasets and can perform specific tasks, such as image generation. Fine-tuning a base model results in additional training to make it more suitable for more specific tasks or datasets, often leading to improved performance.
3. LoRA (Low Range Adaptation):LoRA is a technique used to tune large models more efficiently by introducing additional trainable parameters in the form of low-rank matrices. LoRA only tunes a small subset of parameters during tuning, making the process faster and less resource intensive. LoRA is particularly useful when working with large pre-trained models such as Stable Diffusion, as it allows users to adapt the model to new tasks or styles with a lower computational cost.

Civitai models

Civitas A model refers to a machine learning algorithm trained to produce art or media in a certain style. To create a media-generating model, a dataset representing the desired style or topic is gathered and used for training. The model then generates new and original media by identifying patterns and features from its training data. The result is not an exact copy of the training examples, but rather a unique creation inspired by the dataset. Models can be trained to produce anything from photorealistic images and abstract patterns to various audio arrangements, short stories, or even videos, allowing for the creation of content that would be difficult and time-consuming to produce manually.

Let's look at some Civitai models:

1. Flow

This control point trained model is a very popular model in Civitai that can be downloaded and used locally or optionally directly on the platform. Let's try to generate an image using this stable diffusion model.

I generated a 1024×1024 image with the caption “A person sitting in a tree with a balloon.” You can set the number of images to 1 if you want to spend less credits, or Buzz as they call it. After signing up, you will be offered 100 Buzz.

Note:

Civitai's “create” option allows users to generate images using ai models and may have credit limitations. However, if you download the model and use it locally or on a service that supports it, you should not encounter any restrictions from Civitai.

2. Photon_v1

Let’s look at another stable diffusion checkpoint model in Civitai. Let’s download the model and use it this time. We’ll need a GPU for this, so I’ll be using Google Colab for the demonstration.

We will use the stable broadcast web interface using Automatic 1111: Link

Please note that Alabama It has limited support for Automatic1111 in the free version so it can be difficult as the notebook will disconnect after 5 minutes of use and you will get a warning like “you may be running unauthorized code”. If you have a good GPU in your computer then I will suggest you to do it locally.

Let's look at the code.

Make sure to change the runtime type and select GPU:

1. Step 1: Clone the Automatic1111 repository.

!git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git

1. Step 2: Install the requirements from the text file.

!pip install -r /content/stable-diffusion-webui/requirements.txt

1. Step 3: Download the model and upload it to your Google Drive and then mount the unit.

Let's download the Photon (v1) model from Civitai: Photon from Civitai

Note: You can click on the mount drive option on the top left side of your laptop.

1. Step 4: Let's move the file from the drive to this directory:

“/content/stable-diffusion-webui/models/Stable-diffusion”

!mv /content/drive/MyDrive/photon_v1.safetensors /content/stable-diffusion-webui/models/Stable-diffusion/photon_v1.safetensors

1. Step 5: Now we can run launch.py, use –share to get a publicly accessible link to the web interface.

!python /content/stable-diffusion-webui/launch.py --share

Select photon_v1 in the stable diffusion checkpoint and start generating in the text2img section. As you can see, I specified “A man with an umbrella” and clicked Generate at the top right. Feel free to modify the settings before generating.

You can download the image by right clicking on it; here is the 512×512 image I generated.

3. Lora models in Civitai

Let's see how to use Civitai's Lora models:

We need to download a Lora model and its base model, otherwise we won't be able to use it. I'll demonstrate this with: Vixon Model Lora's Anime/Manga Styles.

The base model for this Lora model is the Pony model, let's download both models from Civitai.

Pony V6 XL Diffusion: Click here

You can follow the steps we performed in the previous section to use the Photon_v1 model. Let's continue with the remaining steps:

1. Step 1: Download the base model and Lora model and upload them to your Google Drive and then mount the unit.
2. Step 2: Create a new directory for the Lora model. Now, move the Lora model to the Lora folder and the base model to the stable release folder.

!mv /content/drive/MyDrive/ponyDiffusionV6XL_v6StartWithThisOne.safetensors /content/stable-diffusion-webui/models/Stable-diffusion/ponyDiffusionV6XL_v6StartWithThisOne.safetensors

!mkdir /content/stable-diffusion-webui/models/Lora

!mv /content/drive/MyDrive/DragonBallZXLP.safetensors /content/stable-diffusion-webui/models/Lora/DragonBallZXLP.safetensors

1. Step 3: Start the web interface by running this line

!python /content/stable-diffusion-webui/launch.py --share

Click on the public URL and you will see this user interface.

Now click on the stable broadcast checkpoint dropdown and select Pony, now click on the Lora section and select Vixon Anime/Manga Styles and we are ready to go.

I incited him ” Goku, green hair, fighting, high quality, Dragon Ball Z, watercolor (medium), traditional technique and clicked generate (I used the trigger words for the model, which helps to get better results, you can find the trigger words on the model page on Civitai – Click here)

This is the image I generated using Vixon's Anime/Manga Lora model.
