Stable Diffusion 3.5 Medium

Stable Diffusion 3.5 Medium (MMDiT-X) is an advanced text-to-image model developed by Stability AI, designed for improved performance in image generation, complex prompt understanding, and typography. Leveraging a Multimodal Diffusion Transformer (MMDiT-X) architecture, this model enhances the quality and coherence of images created from text prompts and is optimized for resource efficiency. With three integrated, pre-trained text encoders and QK normalization for training stability, Stable Diffusion 3.5 Medium provides reliable multi-resolution image generation for both creative and research-based applications.

This model supports multi-resolution training up to 1440p and includes an innovative skip-layer guidance (SLG) for improved structure and anatomy in images. It is ideal for artists, designers, and researchers seeking a balance between output quality and resource requirements, with efficient VRAM usage for various deployment options. The model is available under the Stability Community License, allowing free use for non-commercial projects and commercial use for entities with less than $1M in revenue.

Key Features:

• Enhanced Prompt Understanding: Generates high-quality images from detailed prompts with improved handling of complex scenes and typography.

• Efficient Multimodal Diffusion Transformer (MMDiT-X): Combines self-attention in the initial layers for robust, multi-resolution generation.

• Progressive Mixed-Resolution Training: Supports outputs from 256 to 1440 pixels, with random cropping for diverse aspect ratios.

• Three Text Encoders: Integrated CLIP-ViT and T5 encoders to process and align varied prompt styles for richer context understanding.

• Flexible Deployment: Supports multiple VRAM configurations and quantization for lightweight setups; compatible with ComfyUI, Hugging Face Diffusers, and Stability AI API.

Use Cases:

• Creative Arts and Design: Generate detailed images for visual storytelling, concept art, and digital media.

• Education and Research: Use as a tool for exploring generative models and their creative limitations.

• Content Creation for Marketing: Ideal for mockups, designs, and visual aids in product marketing.

Stable Diffusion 3.5 Medium offers a state-of-the-art generative AI model for users who need flexible, high-quality image creation, combining efficiency with performance in a range of artistic and professional contexts.
