TopazImageEnhanceV2 - ComfyUI Built-in Node Documentation - ComfyUI

Topaz Image Enhance applies industry-standard upscaling and image enhancement to a single input image using Topaz models. It sends the image to the Topaz API, processes it with the selected model, and returns the enhanced result. You can choose from three models: Reimagine, Bloom 2, and Wonder 3.5.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to enhance. Only one input image is supported.	IMAGE	Yes	Single image
`model`	The Topaz enhancement model to use. The selected model determines which model-specific settings appear.	STRING	Yes	`"Reimagine"` `"Bloom 2"` `"Wonder 3.5"`
`output_width`	Zero value means to calculate automatically (usually it will be original size or scaled proportionally to `output_height` if specified). Wonder 3.5 supports upscale factors from 1x to 6x only. Bloom 2 and Wonder 3.5 preserve the input aspect ratio and treat the requested size as a target. (default: 0)	INT	No	0 to 32000
`output_height`	Zero value means to output in the same height as original or scaled proportionally to `output_width` if specified. Wonder 3.5 supports upscale factors from 1x to 6x only. Bloom 2 and Wonder 3.5 preserve the input aspect ratio and treat the requested size as a target. (default: 0)	INT	No	0 to 32000

Reimagine settings

These settings apply when model is set to "Reimagine".

Parameter	Description	Data Type	Required	Range
`prompt`	Optional text prompt for creative upscaling guidance. (default: "")	STRING	Yes	Any text
`creativity`	Creativity level for the enhancement. (default: 3)	INT	Yes	1 to 9
`subject_detection`	Subject detection mode.	STRING	Yes	`"All"` `"Foreground"` `"Background"`
`face_enhancement`	Enhance faces (if present) during processing. (default: True)	BOOLEAN	Yes	true false
`face_enhancement_creativity`	Set the creativity level for face enhancement. (default: 0.0)	FLOAT	Yes	0.0 to 1.0
`face_enhancement_strength`	Controls how sharp enhanced faces are relative to the background. (default: 1.0)	FLOAT	Yes	0.0 to 1.0
`face_preservation`	Preserve subjects’ facial identity. (default: True)	BOOLEAN	Yes	true false
`color_preservation`	Preserve the original colors. (default: True)	BOOLEAN	Yes	true false
`crop_to_fill`	By default, the image is letterboxed when the output aspect ratio differs. Enable to crop the image to fill the output dimensions. (default: False)	BOOLEAN	Yes	true false

Bloom 2 settings

These settings apply when model is set to "Bloom 2".

Parameter	Description	Data Type	Required	Range
`prompt`	Optional text prompt for generation. Leave empty to auto-generate a prompt from the input image. (default: "")	STRING	Yes	Any text
`creativity`	1 is restrained enhancement, 9 is pronounced reinterpretation with newly generated detail. (default: 3)	INT	Yes	1 to 9
`seed`	Seed for reproducible generation. (default: 2)	INT	Yes	1 to 2000
`color_preservation`	Preserve the original colors. (default: True)	BOOLEAN	Yes	true false
`grain`	Add grain to the output image. (default: False)	BOOLEAN	Yes	true false
`grain_model`	Grain model to use. Is ignored if grain is disabled.	STRING	Yes	`"silver"` `"gaussian"` `"grey"`
`grain_strength`	Strength of the grain effect. Is ignored if grain is disabled. (default: 0.5)	FLOAT	Yes	0.0 to 1.0
`grain_size`	Size of the grain particles. Is ignored if grain is disabled. (default: 1.0)	FLOAT	Yes	1.0 to 5.0
`grain_density`	Intensity of the grain effect. Is ignored if grain is disabled. (default: 0.5)	FLOAT	Yes	0.0 to 1.0

Wonder 3.5 settings

These settings apply when model is set to "Wonder 3.5".

Parameter	Description	Data Type	Required	Range
`enhancement_strength`	Enhancement level for varying input conditions. (default: “high”)	STRING	Yes	`"low"` `"medium"` `"high"`
`grain`	Add grain to the output image. (default: False)	BOOLEAN	Yes	true false
`grain_model`	Grain model to use. Is ignored if grain is disabled.	STRING	Yes	`"silver"` `"gaussian"` `"grey"`
`grain_strength`	Strength of the grain effect. Is ignored if grain is disabled. (default: 0.5)	FLOAT	Yes	0.0 to 1.0
`grain_size`	Size of the grain particles. Is ignored if grain is disabled. (default: 1.0)	FLOAT	Yes	1.0 to 5.0
`grain_density`	Intensity of the grain effect. Is ignored if grain is disabled. (default: 0.5)	FLOAT	Yes	0.0 to 1.0

Outputs

Output Name	Description	Data Type
`IMAGE`	The enhanced and upscaled image returned by the Topaz API.	IMAGE
