Features

Stable Diffusion 3.5 Large

Stable Diffusion 3.5 Large is Stability AI’s flagship text-to-image and image-to-image generation model that creates stunning, highly detailed images from text descriptions. With advanced prompt understanding and flexible aspect ratios, it delivers exceptional quality for creative and professional projects.

Why It Stands Out

• Advanced architecture: Built on Stability AI’s latest diffusion technology for superior image quality.
• Dual mode support: Works as both text-to-image and image-to-image generator.
• Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
• Strong prompt adherence: Accurately interprets complex, detailed prompts.
• Flexible aspect ratios: Choose from 1:1, 3:4, 4:3, 16:9, or 9:16 to fit any use case.
• Reproducibility: Use the seed parameter to recreate exact results.

Pro Tips for Best Quality

• Be descriptive in your prompt — include style, mood, lighting, composition, and specific details.
• Use style keywords like “photorealistic,” “digital painting,” “cinematic,” or “anime” to guide the aesthetic.
• Include technical parameters in your prompt like “—ar 16:9” for additional guidance.
• For image-to-image, provide a clear source image and describe the desired transformation.
• Fix the seed when iterating to compare different prompt variations.

Notes

• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on current queue load.
• Please ensure your prompts comply with content guidelines.
