What does Image Critic return?

A score from 0 to 1 and one to three short sentences of feedback. The feedback leaves through Approved when the score reaches your threshold, and through Rejected when it does not.

How many credits does Image Critic cost?

5 credits per run with the default model, Claude Sonnet 4.6. Other models cost up to 20 credits. The all mode scores every check in one call, so it does not cost more.

Which mode should I use?

Use realism or anatomy to catch typical AI mistakes, character-consistency or style-match to compare with a reference image, prompt-adherence to check the prompt, and all to run every check your inputs allow.

Can I check that a character looks like the reference?

Yes. Choose character-consistency and wire the reference picture into the Reference input. The critic checks whether both images show the same person, from the face geometry, the hair and the defining features.

What language is the feedback in?

English, whatever the language of your editor.

Image Critic node — score AI images and route them by pass or fail

Score an image for realism, anatomy, prompt adherence, style or character consistency, and route it by the result to build automatic quality checks.

The Image Critic node scores an image with a vision model and tells you what to fix. You choose what to check, such as realism, anatomy or character consistency, and set a pass mark. The node returns a score from 0 to 1 with short feedback. It sends the feedback out through Approved or Rejected, so the rest of the workflow can act on the verdict.

When to use it

Check every result of Generate Image and send the failures to a fix step.
Check that every generated image of a character matches its reference picture.
Score images against a brand's style reference.
Catch broken hands, eyes or faces before Lip Sync or Motion Transfer.
Compare several candidates by their aesthetic score.

Quick start

Add the node

Press Tab on the canvas and choose Image › Understand › Image Critic.

Connect the image and what to compare with

Drag the image to check into the Image input. For character-consistency and style-match, also wire the reference picture into Reference. For prompt-adherence, wire the prompt into Prompt, or type it in the settings panel.

Choose the check

Open the settings panel. Choose a Mode and set the Threshold, the score an image needs to pass.

Connect the outputs and run

Wire Approved to the step for good images and Rejected to the fix step. Connecting only one of them is fine. Click Run.

Image Critic checks the anatomy of a generated image; when it fails, the feedback becomes the prompt of a fix step that uses the first image as a reference.

Inputs

Input	Accepts	What it does
Image	Image nodes, such as Generate Image, Modify Image and Upload Image	The image to score. Required.
Reference	Image nodes, such as Upload Image	The image to compare with. Needed for character-consistency and style-match, and used by all when it is connected.
Prompt	Text nodes, such as Text	The prompt the image was meant to follow. Needed for prompt-adherence, and used by all when it is set. A wired prompt wins over a typed one.

Image Critic has two outputs. Both carry the same feedback text, and only one of them carries it on each run:

Output	Carries the feedback when
Approved	The score is equal to or above the threshold
Rejected	The score is below the threshold

Modes

Mode	What it scores	Needs
`realism`	Photorealism. It calls out plastic skin, broken anatomy and impossible lighting.	Image
`anatomy`	Typical AI failures: hands, eyes, extra limbs, broken faces	Image
`aesthetic`	Composition, lighting, framing and color, graded like cinematography	Image
`prompt-adherence`	Whether the image shows what the prompt asked for	Image and prompt
`character-consistency`	Whether two images show the same person: face geometry, hair and defining features	Image and reference
`style-match`	How closely the palette, mood and treatment follow a style reference	Image and reference
`all`	Every check that the connected inputs allow. The score is the lowest of the checks.	Image, plus the reference and the prompt when you have them

Settings

Setting	What it does
Mode	What to check. The default is `realism`. See Modes.
Threshold	The pass mark, from 0 to 1. The default is 0.7. An image is approved when its score is equal to or above the threshold.
Prompt (or wire via input edge)	The prompt to check against. It appears for `prompt-adherence` and `all`.
AI Model	The vision model. The default is Claude Sonnet 4.6.
Reasoning Effort	How much the model reasons before it answers, on models that support it. The default is Auto (model default).
Advanced mode	Gemini models only. Runs the model on the provider directly, so that Temperature and Max Tokens take effect. Costs one credit tier more.
Pre & post text	Text that is always added before and after the prompt. It is hidden from people who use your workflow as an app. See Prompt pre and post text.

Changing the mode after a run clears the old score, so a score never belongs to another check. Changing only the threshold re-checks the existing score at once, without a new run.

Build a fix step

The feedback is written as short instructions, such as "Reshape the left hand", so it works as an edit prompt.

Set the Threshold near 0.7.
Wire Rejected into the prompt of the node that fixes the image. For example, use the Prompt input of a second Generate Image node that has the first image as a reference.

Both outputs carry text, not the image. Take the image itself from the node that generated it.

For prompt-adherence, wire the same prompt that you gave the generation node. A different prompt gives a misleading score. For character-consistency, wire the reference straight from the source of truth, such as an Upload Image node or the character's approved picture. A regenerated copy may have drifted.

Credits

A run costs 5 credits with the default model, Claude Sonnet 4.6. Other models cost up to 20 credits, depending on their tier, and Advanced mode moves the price up one tier. The all mode scores every check in one call, so it does not cost more than a single check.

Tips

Use all for batch checks. One call scores every dimension, at the price of one check.
Expect English feedback. The feedback is written in English, whatever the language of your editor.
Tune the pass mark without paying again. Changing the threshold re-uses the existing score.
Pick the best of several. To choose one image from many candidates, see Choose Best. For text checks, use QA Check.
