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

The speaker introduces the topic of AI-generated thumbnails and image creation, highlighting the popularity of AI in this field. They mention using an open-source AI called 'Stable Diffusion' that was made public in August 2022, allowing free personal and commercial use. The speaker expresses excitement about the innovation of having such high-quality image generation AI available for free and with open-source code. They plan to demonstrate the process of generating images using Stable Diffusion, mentioning the various ways to use it, including through web browsers and by running it on one's own machine. The speaker, being an engineer, is particularly interested in running the AI locally but acknowledges the high hardware specifications required, especially for the graphics card and VRAM, which are crucial for image processing.

The speaker discusses the challenge of running Stable Diffusion locally due to its high hardware requirements, which are not typically found in standard laptops or PCs. They mention that gaming PCs or those with high-end graphics cards are needed to handle the AI's demands. However, not everyone has access to such machines. To overcome this, the speaker suggests using cloud services, which allow users to rent high-spec servers with powerful VRAM. They compare various cloud service providers like AWS and GCP and decide to use Alibaba Cloud due to its high quality, similarity to AWS in terms of usability, and cost-effectiveness. The speaker guides through the process of creating an account on Alibaba Cloud and setting up a server with a GPU, which is necessary for running image processing AI like Stable Diffusion.

The speaker details the steps to set up and run Stable Diffusion on Alibaba Cloud. They start by logging into their Alibaba Cloud account and creating a new server instance, choosing a GPU-enhanced type to meet the AI's requirements. The speaker selects an 'on-demand' payment method for flexibility and installs necessary libraries on the server, including Git for code management. They then proceed to install a wrapper library called 'Diffusers' that simplifies the use of Stable Diffusion. The speaker writes a short Python script using this library, which requires only a few lines of code. The key component is the 'prompt', which acts as a creative input for the AI to generate images. The speaker shares their experience with different prompts and demonstrates the process of generating various images, showcasing the AI's capability to create high-quality, imaginative artwork.

The speaker concludes by reflecting on the ease and power of creating images using Stable Diffusion and Alibaba Cloud. They marvel at the quality of the images generated and the potential of AI in the field of image creation. The speaker also appreciates the cost savings offered by Alibaba Cloud, recommending it for those looking to save on expenses while still needing high-performance computing resources. They invite viewers to share their thoughts and feedback through comments and likes, expressing gratitude for watching the video. The speaker ends on a note of excitement about the future of AI-generated content, hinting at the possibility of using it for their YouTube thumbnails.
