The editor of Downcodes learned that Stability AI once again demonstrated its breakthrough progress in the field of AI and launched the new Stable Diffusion 3.5 Medium model! This free commercial, high-performance and easy-to-use AI painting tool will completely change the public’s AI creation experience. It breaks the reliance of previous AI painting tools on high-performance hardware, allowing more people to easily experience the charm of AI painting.
Stability AI once again breaks through technical barriers and launches the new Stable Diffusion3.5Medium model. This AI painting tool for the public is not only completely free and open for commercial use, but more importantly, it achieves the perfect balance of high performance and popularity.
This model uses the multi-mode diffusion transformer (MMDiT-X) architecture and has a streamlined design of 2.5 billion parameters, cleverly solving the hardware threshold problem for ordinary users. It only requires 9.9GB of video memory and can run smoothly on most consumer-grade graphics cards, truly realizing the vision of being available to everyone.

In terms of technological innovation, the model integrates three pre-trained text encoders and introduces QK standardization technology to improve training stability. It is particularly worth mentioning that the dual attention module design in the first 12 transformation layers allows the model to significantly improve image quality, layout effects, and complex prompt understanding.
The training process of the model combines synthetic data and selected public data, and adopts a hybrid training strategy of progressive resolution improvement to ensure the diversity and quality of the generated images. Compared with similar medium-sized models, it shows obvious advantages in image generation effects and processing speed.
However, users need to pay attention to some details during use: too long prompt words may cause defects on the edges of the image; it is recommended to use the skip layer guidance sampling method to optimize the structural integrity of the image; at the same time, it should be noted that due to differences in training data distribution, The same prompt words may produce different creative effects.
The release of this model not only provides individual creators and start-ups with convenient AI creation tools, but also reflects Stability AI’s determination to promote the popularization of AI technology. Whether it is used for artistic creation or educational development, it will bring the possibility of AI creation to a wider user group.
