Available Nodes

Image Generation Nodes

These nodes create high-quality images from text or image prompts, generating photorealistic or artistic results with support for various aspect ratios. [API docs].

Node	Description
Text2Image Base	Generates images from text prompts, serving as the foundation for text-based image creation.
Text2Image Fast	Optimized for speed, this node generates images from text prompts with faster results while maintaining quality.
Text2Image HD	Optimized for high-resolution outputs, this node generates detailed and sharp visuals from text prompts.

Tailored Generation Nodes

These nodes use pre-trained tailored models to generate images that faithfully reproduce specific visual IP elements or guidelines. [API docs].

Node	Description
Tailored Gen	Generates images using a trained tailored model, reproducing specific visual IP elements or guidelines. Use the Tailored Model Info node to load the model's default settings.
Tailored Model Info	Retrieves the default settings and prompt prefix of a trained tailored model, which can be used to configure the Tailored Gen node.

Image Editing Nodes

These nodes modify specific parts of images, enabling adjustments while maintaining the integrity of the rest of the image. [API docs].

Node	Description
RMBG 2.0 (Remove Background)	Removes the background from an image, isolating the foreground subject.
Replace Background	Replaces an image’s background with a new one, guided by either a reference image or a prompt.
Expand Image	Expands the dimensions of an image, generating new content to fill the extended areas.
Eraser	Removes specific objects or areas from an image by providing a mask.
GenFill	Generates objects by prompt in a specific region of an image.
Erase Foreground	Removes the foreground from an image, isolating the background.

Product Shot Generation Nodes

These nodes create high-quality product images for eCommerce workflows. [API docs].

Node	Description
ShotByText	Modifies an image's background by providing a text prompt. Powered by BRIA's ControlNet Background-Generation.
ShotByImage	Modifies an image's background by providing a reference image. Uses BRIA's ControlNet Background-Generation and Image-Prompt.
