11 parameters · 2 required · 9 optional
| Parameter | Type | Required | Description |
|---|---|---|---|
image | string | Required | URL of image to use for image-to-image generation. |
prompt | string | Required | The prompt to generate an image from. |
seed | integer | Optional | The same seed and the same prompt given to the same version of the model will output the same image every time. |
loras | object[] | Optional | The LoRAs to use for the image generation. You can use any number of LoRAs and they will be merged together to generate the final image. · Default: [] |
aspect_ratio | string | Optional | The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 21:916:93:24:35:41:14:53:42:39:16 |
output_format | string | Optional | The format of the generated image. · Options: jpeg, png · Default: "jpeg" jpegpng |
guidance_scale | number | Optional | The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you. · Min: 0 · Max: 35 · Default: 3.5 |
preprocess_depth | boolean | Optional | If set to true, the input image will be preprocessed to extract depth information. This is useful for generating depth maps from images. · Default: true |
num_inference_steps | integer | Optional | The number of inference steps to perform. · Min: 1 · Max: 50 · Default: 28 |
control_lora_strength | number | Optional | The strength of the control lora. · Min: 0 · Max: 2 · Default: 1 |
control_lora_image_url | string | Optional | The image to use for control lora. This is used to control the style of the generated image. |

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

Flux Control Lora Canny
Flux Control Lora Canny belongs at the structure-led visual development with an adapted aesthetic stage of a visual workflow. Rather than treating the model as an isolated demonstration, teams can place it inside briefing, review, selection, and handoff practices where the workflow keeps a line-based plan central while allowing a learned treatment to guide the finished look. This positioning clarifies why the model earns a place in a real creative pipeline and what kind of decision it helps people make.
A practical use of Flux Control Lora Canny is architecture studies, product silhouettes, illustration cleanup, and branded layouts where approved contours should organize the result. Begin by agreeing on the creative objective and review criteria, prepare only the source material needed for that objective, and compare results against audience, brand, editorial, and production needs. Technical request choices remain documented below so the prose can stay focused on planning and creative value.
Highlights
Contour-locked composition. Preserves important outlines and layout while regenerating color, texture, and appearance.
Shape-faithful restyling. Changes visual treatment without losing the source edge map's silhouettes and object boundaries.
Prompt-and-edge fusion. Reconciles written art direction with structural line guidance in one still image.
Fine boundary control. Retains small architectural, product, and character contours that free generation may drift away from. Control-LoRA couples structural conditioning with a lightweight learned adapter so guidance remains strong without replacing the base generator.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact FLUX capability | The intended task belongs to a different media workflow |
| Required source and control media are available | Necessary assets or usage rights are unavailable |
| Creative direction can state change and preservation goals | Output must be deterministic at pixel or frame level |
| Supported dimensions and formats match final delivery | Placement requires unsupported specifications |
| An asynchronous generated result fits production | A live frame-synchronous response is mandatory |
Prompt Guide
Lead with the main subject and action, then specify composition, context, lighting, materials, style, typography, and atmosphere. For editing, identify each source and clearly separate the requested transformation from the subjects, regions, geometry, or identity that must remain unchanged.
