How this service works
Stable Diffusion 3.5 family — choose model for quality/speed/cost balance.
Output
Returns a generated image file in the requested format (jpeg, png, or webp) based on the text prompt and selected SD3.x model. The image reflects the prompt, negative prompt exclusions, aspect ratio, and guidance scale settings provided.
Example use cases
Example prompt
“Generate an image of a misty Japanese forest at dawn with cherry blossoms falling, ultra-realistic style, no people or animals, using the sd3.5-large model in a 16:9 landscape aspect ratio and output as PNG.”
Technical details
Endpoint
POSThttps://stability-ai.mpp.paywithlocus.com/stability-ai/generate-sd3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need high-quality Stable Diffusion 3.x image generation with flexible model tiers (flash for speed/cost, large for quality), support for both text-to-image and image-to-image modes, and fine-grained control over guidance scale, seed, aspect ratio, and negative prompts. Prefer sd3.5-flash ($0.029) for cost-sensitive or high-volume use cases, and sd3.5-large for maximum quality.
Side effects
- Invalid or missing prompt returns 400 Bad Request
- Unsupported model name returns validation error
- Image input required but not provided for image-to-image mode
- Strength value out of 0–1 range causes parameter error
- Unsupported aspect ratio string may cause error
- Payment failure or insufficient USDC balance blocks request
- Rate limiting may return 429 Too Many Requests
