Stable Diffusion と Midjourney のどちらを選ぶか迷っていますか？この比較を最初に読んでください！

Facing the increasingly heavy content creation tasks, such as creating marketing visuals, conceptual designs, and illustration drawings, more and more creators are starting to rely on AI image generation tools. However, when the two popular players in the market – Stable Diffusion and Midjourney – are presented, many people will be torn: which one is the most suitable for them?

As leading text-to-image AIs, both of these tools can quickly generate high-quality images based on text descriptions, but they have obvious differences in style, controllability, and user experience. Today, we will conduct a comprehensive comparison of their advantages and disadvantages to help you make a wise choice.

What are Stable Diffusion AI and Midjourney AI?

Stable Diffusion, developed by Stability AI, is an open-source image generation model that focuses on “freedom” and “controllability”. It uses advanced Latent Diffusion technology, which can efficiently generate complex images in the compressed latent space. The biggest highlight of this model lies in its high degree of customization – you can fine-tune the style through prompt words, install various plugins (such as ControlNet, LoRA fine-tuning) to expand its functions, and even build your own exclusive drawing engine locally. Stable Diffusion is especially suitable for professional users who need fine-grained control, such as in scenarios like game development, art design, and scientific research projects. It requires a certain level of technical skills, but the rewards are also extremely high.

Midjourney, on the other hand, is an AI image generation platform developed by the independent team Midjourney Inc., which focuses on “artistry and ease of use”. Its most prominent feature is the ultimate aesthetic appeal of its images – each work comes with a unique sense of dreaminess and imagination, making it very suitable for creativity-driven scenarios, such as brand visuals, story illustrations, poster designs, etc. The operation method is also very user-friendly. There is no need to install complex software. You just need to send text commands through the Discord server to generate images, which is suitable for quick start and instant creation. Although Midjourney is not as deep in customization as Stable Diffusion, it stands out in terms of the artistic unity and visual impact of its finished products, and is highly favored by content creators and freelancers.
