Features

Stable Diffusion 3.5 Medium

Generate stunning images from text prompts with Stability AI’s Stable Diffusion 3.5 Medium. This versatile model delivers high-quality results for both text-to-image and image-to-image generation, with excellent prompt adherence and artistic flexibility.

Why It Looks Great

• Strong prompt understanding: Accurately interprets complex, detailed descriptions including style, mood, and composition.
• Dual mode support: Use text-only for pure generation, or add a reference image for guided transformations.
• Flexible aspect ratios: Supports multiple output formats for any creative need.
• Prompt Enhancer: Built-in tool to refine and expand your descriptions for richer results.
• Reproducible outputs: Use the seed parameter to recreate exact images or explore variations.
• Balanced quality: Medium model offers an optimal trade-off between speed and visual fidelity.

Parameters

How to Use

1. Write your prompt — describe the image in detail, including subject, style, lighting, and mood.
2. Use Prompt Enhancer (optional) — click to refine your description for better results.
3. Add reference image (optional) — upload an image for image-to-image transformation.
4. Choose aspect ratio — select the format that fits your needs.
5. Set seed (optional) — use -1 for random, or a specific number for reproducible results.
6. Run — click the button to generate.
7. Download — preview and save your generated image.

Pricing

Flat rate per image generation.

Examples

Best Use Cases

• Concept Art & Illustration — Generate detailed artwork, landscapes, and character designs.
• Marketing & Advertising — Create custom visuals for campaigns without stock photos.
• Creative Exploration — Rapidly iterate on visual ideas and artistic directions.
• Style Transfer — Transform reference images into new artistic interpretations.
• Storytelling & Storyboarding — Visualize scenes and narratives with consistent styling.

Example Prompts

• “A tumultuous ocean violently crashing against black reefs as a storm approaches, dark heavy clouds, lightning illuminating churning waves, dramatic oil painting style”
• “A cozy coffee shop interior with warm lighting, rain on the windows, vintage furniture, soft atmospheric mood”
• “Portrait of an astronaut in a field of wildflowers, cinematic lighting, photorealistic, golden hour”
• “Abstract geometric shapes floating in space, vibrant neon colors, minimalist design”
• “Ancient temple ruins overgrown with jungle vines, misty atmosphere, rays of sunlight breaking through”

Pro Tips for Best Results

• Be descriptive — include style references, lighting conditions, color palette, and mood.
• Mention artistic styles or artists for specific aesthetics (e.g., “in the style of impressionism”).
• Use the Prompt Enhancer to add professional-quality details to simple ideas.
• For image-to-image, the reference strongly guides composition — choose images with the structure you want.
• Fix the seed when iterating on prompts to isolate the effect of text changes.
• Negative concepts can be implied by describing what you do want rather than what you don’t.

Notes

• If using a URL for the reference image, ensure it is publicly accessible.
• The enable_base64_output option is only available through the API, not the web interface.
• Generation time may vary based on current queue load.
