Parameter | Type | Required | Description |
---|---|---|---|
model_id | string | Required | The ID of the model to run (flux-sketch-smudge) |
api_key | string | Required | Your API key for authentication (sent via Bearer token in the Authorization header) |
prompt | string | Required | Describe what you want to generate |
aspect_ratio | string | Required | Aspect ratio for the generated image |
prompt_strength | number | Optional | Prompt strength when using img2img. 1.0 corresponds to full destruction of information in image |
num_inference_steps | number | Optional | Number of denoising steps. Recommended range is 28-50, and lower number of steps produce lower quality outputs, faster. |
guidance | number | Optional | Guidance for generated image |
seed | array | Optional | Random seed. Set for reproducible generation |
output_format | string | Optional | Format of the output images |
output_quality | number | Optional | Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs |
lora_scale | number | Optional | Determines how strongly the main LoRA should be applied. Sane results between 0 and 1 for base inference. For go_fast we apply a 1.5x multiplier to this value. |
megapixels | string | Optional | Approximate number of megapixels for generated image |

Cost Per Generation is a pricing model where you’re charged based on each individual output the model generates. Instead of billing for compute time, you pay a fixed cost for every generation request, regardless of how long it takes. This makes costs predictable since each generated result incurs its own set rate.
Note: Pricing is subject to change. For bulk usage or custom packages, please contact us.
