Stable Diffusion 3.5 Large Turbo is Stability AI's revolutionary speed-focused image generation model that redefines the speed-quality ratio in AI art. It's a distilled version of SD3.5 Large capable of creating professional-grade, high-quality images in just 4 inference steps.
The key innovation is Multimodal Diffusion Transformer (MMDiT) architecture with Adversarial Diffusion Distillation (ADD) that features improved performance in image quality, typography, complex prompt understanding, and resource-efficiency, with a focus on fewer inference steps.
Technically, the model uses three fixed, pretrained text encoders with QK-normalization. The model generates high-quality images with exceptional prompt adherence in just 4 steps, making it considerably faster than Stable Diffusion 3.5 Large.
The model is available under Stability Community License: free for research, non-commercial, and commercial use for organizations with less than $1M in total annual revenue. Designed to run efficiently on standard consumer hardware. Perfect for rapid content creation, design prototyping, artistic works, and real-time application integration with enterprise-grade accessibility and performance.
