Negative Prompt negative_prompt	string	Optional	What to exclude from the image
Aspect Ratio aspect_ratio	options	Optional	Aspect Ratio. Options: 1:1 (Square), 16:9 (Landscape), 9:16 (Portrait), 4:3, 3:2, 21:9 (Ultrawide)
Output Format output_format	options	Optional	Output Format. Options: PNG, JPEG, WebP
Seed seed	string	Optional	Random seed for reproducible results. Leave empty for random.

Sample request

{
  "prompt": "e.g. A photorealistic sunset over mountains, 4K, dramatic lighting",
  "negative_prompt": "e.g. blurry, low quality, text, watermark",
  "aspect_ratio": "{{trigger.aspect_ratio}}",
  "output_format": "{{trigger.output_format}}",
  "seed": "e.g. 42"
}

Returns

{
  "seed": 42,
  "image": "base64-encoded-image-data...",

FAQ

Questions about Stability AI Generate Image.

What does the Stability AI Generate Image action do in Stability AI?

Generates images using Stable Diffusion models (SD3.5, SDXL variants). For workflows that want first-party Stability access with their full feature set.

What inputs does Stability AI Generate Image require?

Required: Prompt. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Stability AI returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Stability AI Generate Image support batch operations?

Yes. Run Stability AI Generate Image inside a Loop node to process arrays. Tiny Command handles Stability AI's rate limits automatically so you don't have to throttle manually.
