• 0.5: ControlNet guidance is only applied during the first half of inference steps

Default values:

• 0.5 for Canny modality
• 0.6 for all other modalities

maximum1

• 0.0: ControlNet guidance starts at the beginning of the inference steps
• 0.5: ControlNet guidance starts at the middle of the inference steps

maximum0.9

minimum0

disableMerging: optional boolean

If set to true, the entire input image will likely change during inpainting. This results in faster inferences, but the output image will be harder to integrate if the input is just a small part of a larger image.

disableModalityDetection: optional boolean

If false, the process uses the given image to detect the modality. If true (default), the process will not try to detect the modality of the given image.

For example: with pose modality and false value, the process will detect the pose of people in the given image with depth modality and false value, the process will detect the depth of the given image with scribble modality and truevalue, the process will use the given image as a scribble

⚠️ For models of the FLUX schnell or dev families, this parameter is ignored. The modality detection is always disabled. ⚠️

guidance: optional number

Controls how closely the generated image follows the prompt. Higher values result in stronger adherence to the prompt. Default and allowed values depend on the model type:

• For Flux dev models, the default is 3.5 and allowed values are within [0, 10]
• For Flux pro models, the default is 3 and allowed values are within [2, 5]

minimum0

height: optional number

• canny
• depth:0.5,pose:1.0
• canny:0.5,depth:0.5,lines:0.3

negativePrompt: optional string

The prompt not to guide the image generation, ignored when guidance < 1 (example: “((ugly face))”) For Flux based model (not Fast-Flux): requires negativePromptStrength > 0 and active only for inference types txt2img / img2img / controlnet.

negativePromptStrength: optional number

Only applicable for flux-dev based models for txt2img, img2img, and controlnet inference types.

Controls the influence of the negative prompt. Default 0 means the negative prompt has no effect. Higher values increase negative prompt influence. Must be > 0 if negativePrompt is provided.
