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 stretchorcenter_cropresizing
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.
