ComfyUI-bitpoet-IG4Inpaint

ComfyUI conditioning node for reference-conditioned Ideogram 4 LoRAs trained with the ideogram4_reference_conditioning_v1 sequence contract.

This enables inpainting with the Ideogram 4 model.

Status

This is an alpha release. Use at your own risk.

Requirements

This node requires the accompanying native ComfyUI Ideogram 4 changes that pack:

text | noisy output | clean reference

The reference uses indicator 4, relative MRoPE time coordinate 1, and an Ideogram model timestep of 1.0. Only output-token predictions are returned to the sampler.

A ComfyUI clone with the changes can be found at my clone of the repo in the dev-ideogram4-inpaint branch.

Node

Ideogram 4 Reference Conditioning accepts:

• Positive Ideogram 4 conditioning
• One reference image
• The Flux 2 / Ideogram 4 VAE
• The target Empty Flux 2 Latent
• stretch or center_crop resizing

It returns the updated positive conditioning, the encoded reference latent, and the resized reference preview.

Connect only its positive-conditioning output to Dual Model CFG Guider. Leave the unconditional Ideogram 4 model and negative conditioning unchanged.

stretch is the default because it matches the current ai-toolkit training preprocessing.

Example workflow

An example is bundled at:

workflows/ideogram4_reference_workflow.json

Copy workflows/idoinpaint_reference.png into ComfyUI's input folder, or select another image in the workflow's Load Image node.

Put a bbox where you want your inpainting to happen and describe the change in the bbox's description. Do not fill in any other fields.

Use "Default" or "Quality" mode. Turbo will mess up the image.
