💻 Using Stable Diffusion without High-End Hardware

This paragraph introduces the concept of utilizing Stable Diffusion for free without the need for a high-end CPU. It addresses the audience who may not have advanced computer specifications and offers a solution through a free Google Colab notebook. The speaker shares a method to use Stable Diffusion by installing desired models within the notebook. The process involves changing the runtime to T4 GPU, connecting to the GPU, and running specific cells within the notebook. The speaker also mentions that the notebook was shared by another individual and gives credit where it's due.



💡Stable Diffusion

Stable Diffusion is an AI model that generates images from text prompts. It is a form of deep learning that uses a process called diffusion to create realistic or stylized images. In the video, it is the primary tool being discussed, with the presenter explaining how to use it for free on Google Colab without needing a high-end CPU.

💡Google Colab

Google Colab is a cloud-based platform that allows users to write and execute Python code in their browser, with the option to use GPU resources for more intensive tasks. It is highlighted in the video as a way to access powerful computing capabilities without investing in expensive hardware.

💡High-end CPU

A high-end CPU, or Central Processing Unit, is a critical component of a computer system that performs most of the processing inside the computer. High-end CPUs are typically more powerful and expensive, offering better performance for tasks like AI model training and image generation. The video addresses that it is not necessary to have one to use Stable Diffusion, as Google Colab can be used instead.


The T4 GPU, or Tensor Processing Unit, is a type of accelerator developed by Google that is designed for machine learning and AI workloads. It is more efficient at these tasks compared to a standard CPU. In the context of the video, selecting a T4 GPU in Google Colab allows users to run the Stable Diffusion model without needing their own hardware.

💡Stable Diffusion Models

Stable Diffusion models refer to different versions of the AI model that can be used for image generation. These models may vary in their level of detail, style, or the type of images they produce. The video provides information on how to install and select different models within the Google Colab notebook.

💡Invoke AI

Invoke AI appears to be the interface or platform within the Google Colab notebook that allows users to interact with the Stable Diffusion model. It is where users can input text prompts and receive generated images, as well as manage the models they have installed.

💡Text to Image

Text to Image is a feature in AI models like Stable Diffusion that generates images based on textual descriptions provided by the user. It is a form of Generative AI that can create a wide variety of images from simple to complex prompts.

💡Model Manager

The Model Manager is a tool or section within the interface that allows users to manage the AI models they have installed or wish to use. This includes adding new models, removing existing ones, or selecting which model to use for generating images.


Upscaling refers to the process of increasing the resolution or quality of an image. In the context of the video, it is an option provided to users within the interface to enhance the images generated by the Stable Diffusion model.

💡Download Image

Download Image is a feature that allows users to save the generated images to their local storage. It is an essential part of the process, enabling users to keep the results of their AI-generated content.


Community, in this context, refers to a group of individuals who share common interests and interact with each other regularly, often through online platforms. The video creator mentions a WhatsApp Community where they share the latest news and cool stuff, indicating a space for like-minded individuals to connect and engage with the content.
