このサムネイル、AIが30秒で作りました【Stable Diffusion】

The speaker begins by introducing the AI-generated thumbnail for the video, expressing excitement about the capabilities of AI in image generation. They mention the significant buzz around AI in 2022, particularly with the open-source AI called 'Stable Diffusion' that was released in August 2022. This AI allows free personal and commercial use and has its code publicly available, which the speaker finds incredibly innovative. They aim to demonstrate the process of generating images using Stable Diffusion and discuss the various ways to use it, highlighting the limitations of browser-based services and the need for high-spec PCs, especially those with powerful GPUs, to run such AI.

The speaker discusses the challenges of running AI like Stable Diffusion on a standard PC due to the high specifications required, particularly in graphics processing. They introduce the idea of using cloud services as a solution, allowing access to high-spec servers without the need for personal high-end hardware. They choose Alibaba Cloud, a major global cloud service provider known for its quality and cost-effectiveness, over other services like AWS or GCP. The speaker appreciates Alibaba Cloud's similarity to AWS, which lowers the learning curve for those familiar with AWS. They guide through the process of creating an account, logging in, and setting up a server instance with a GPU, which is essential for running image generation AI.

After setting up the server on Alibaba Cloud, the speaker proceeds to connect to it and install necessary libraries. They install Git to manage the Stable Diffusion code and then proceed to install a wrapper library called 'Diffusers' that simplifies the use of Stable Diffusion. The speaker outlines the steps to install this library and configure the server environment. They write a short Python script using the Diffusers library to generate images, emphasizing the ease of creating such scripts due to the library's simplicity. The script uses prompts as a basis for the AI to generate images, and the speaker shares their experience with different prompts, demonstrating the AI's ability to create diverse and high-quality images.

The speaker showcases the AI-generated images, expressing amazement at the quality and diversity of the results. They discuss the ease of generating such images using Stable Diffusion and the power of cloud computing in making high-spec AI accessible. They conclude by thanking the viewers, encouraging feedback, and expressing their intention to use Stable Diffusion for future YouTube thumbnails. The speaker also reflects on the convenience and cost-effectiveness of using Alibaba Cloud for such tasks, recommending it for those looking to save on costs while benefiting from high-performance computing resources.
