Introduction

Are you looking for a way to use stable diffusion for free without investing in a high-end CPU? If you're like me and don't have access to high-end computer specs, then you've come to the right place. In this article, I'm going to share a free Google Collab notebook that allows you to use stable diffusion and even install your desired models. So let's dive into the details and get started!

Setting up the Google Collab Notebook

To begin, we need to set up the Google Collab notebook and configure the runtime settings. Follow the instructions below:

1. Go to the runtime settings and select "Change Runtime".
2. Make sure to choose the T4 GPU as your default instead of the CPU.
3. Click "Save" to apply the changes.
4. Click on the "Connect" button to establish a connection to the GPU.

Installing Stable Diffusion Models

Once the runtime settings are configured, we can proceed with installing the stable diffusion models. Here's how:

1. In the Google Collab notebook, locate the first cell and click on the play button to run the code.
2. Wait for the process to execute, which can take around 3 to 4 minutes.
3. Once the first cell displays a green checkmark, click on the provided blue link.
4. You will find a list of stable diffusion models that can be installed in the Google Collab notebook.
5. By default, the stable vision realistic version 5 is selected. If you want to install a different version, simply replace the existing code.
6. If you wish to install custom models, proceed to run the Second cell. This process may also take a few minutes.

Using Invoke AI and Generating Images

After the stable diffusion models are installed, we can utilize Invoke AI to generate images. Here's how:

1. Run the third cell in the Google Collab notebook.
2. Wait for the "Invoke AI" link to appear before proceeding.
3. Select the first link that appears, which will take you to the Invoke AI interface.
4. Within Invoke AI, you can provide prompts, choose the number of images, and specify the number of steps.
5. There is also a list of installed models that you can explore.
6. To install additional models, access the model manager and import models from reputable sources.
7. Once you've configured all the parameters, click "Invoke" to generate the image.
8. The image generation process may take some time, so be patient.

Upscaling Images

If you want to upscale your generated image, it's possible within the Google Collab notebook. Follow these steps:

1. Click on the "Upscale" button.
2. Select your desired upscaling model, such as the real s4x plus.
3. Click "Upscale Image" to initiate the upscaling process.
4. Wait for the image to be upscaled.

Conclusion

Using stable diffusion without investing in high-end CPUs is now accessible through the Google Collab notebook. By following the steps outlined in this article, you can set up the notebook, install stable diffusion models, generate images using Invoke AI, and even upscale the images. This opens up opportunities for creativity and experimentation in the field of stable diffusion. Give it a try and unlock the potential of stable diffusion with limited resources!
