Stable Diffusion 3 Capabilities
---

The most advanced Stable Diffusion model with improved prompt understanding, typography, and composition.

Improved Typography SD3 handles text in images natively — render logos, signs, and labels accurately. Unlike previous versions, Stable Diffusion 3 understands text prompts that include specific words and letters, generating readable text within images.

Enhanced Composition Better spatial understanding for complex multi-subject scenes. SD3 accurately positions multiple objects and characters according to detailed prompts, maintaining correct spatial relationships and scene coherence.

Superior Prompt Following SD3 follows long, detailed prompts with higher fidelity than previous versions. Specify intricate scenes, art styles, lighting conditions, and composition details — SD3 understands and executes complex creative instructions.

Multiple Aspect Ratios Generate images in landscape, portrait, square, and custom aspect ratios. SD3 natively supports various aspect ratios without cropping or distortion, perfect for social media, print, and web content.
