If you're unsure of how to access Stable Diffusion using Google Colab, don't worry - we've got you covered!

Stable Diffusion is a powerful AI image generator that has been trained on billions of images and can produce results similar to those you get from DALL-E 2 and MidJourney. In this guide, we'll walk you through the steps of accessing Stable Diffusion through Google Colab and generating images from your text prompts. Let's dive in!

How To Access Stable Diffusion Using Google Colab

To achieve decent results with Stable Diffusion on your PC, you need at least 6GB of VRAM (GPU). However, most of us don't have that much VRAM available on our computers. That's where Google Colab comes in handy.

Google Colab is a cloud-based coding environment that offers a computing infrastructure powerful enough to run Stable Diffusion. The only downside is that you need Colab Pro to run Stable Diffusion, as the free version has insufficient VRAM for sampling.

Assuming that you have Colab Pro, let's dive into the process.

Setting up Stable Diffusion

At first, Google Colab may seem overwhelming and confusing, especially if you're not familiar with coding. But don't worry! You don't need to understand the code to run Stable Diffusion on Colab. All you have to do is follow these simple steps:

  1. ​Go to this Google Colab Notebook.
  2. Make sure your hardware accelerator is set to GPU and your runtime shape is set to High-RAM. To do this, click on Runtime > Change runtime type in the top left-hand corner of the window, make the necessary changes, and hit Save.
  3. Set up Stable Diffusion by clicking on the down arrow icon on the left of "Setup" to unexpand the block, and then hit the play button to run the block of code. Wait for it to finish execution.

Once you've completed these steps, you can start generating images with Stable Diffusion using Google Colab. It's that simple! Keep reading for more information on how to generate images.

Generating images with Stable Diffusion

Well done! You have successfully completed the setup for Stable Diffusion and now it's time to unleash your creativity.

To generate images, you need to provide a text prompt. Here's how to do it.You should now see a code block that looks similar to the one in the image above. As you may have guessed, you need to enter your text or prompt inside the quotes next to the --prompt command.

For example: --prompt "Iron Man making breakfast"

Once you have entered your prompt, click the play button to execute the code block. Your image will be generated in just a few seconds. Adjusting the --ddim_steps parameter can improve the image's quality and alignment with your prompt, but it will increase the generation time.

It's worth noting that this tool includes an NSFW filter. To create NSFW images, you must use Stable Diffusion on your own computer.
