Krea 2 AnyPaint

ComfyUI Krea 2 AnyPaint

Native ComfyUI nodes for the yijunwang2/krea2-anypaint functional adapter. AnyPaint adds arbitrary-mask inpainting, outpainting, and mixed image editing to Krea 2 Turbo.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/alexw5702-afk/krea2-anypaint

Restart ComfyUI, then place krea2_anypaint_rank32.safetensors in ComfyUI/models/loras.

Requirements

• A current ComfyUI build with native Krea 2 support.
• krea2_turbo_int8_convrot.safetensors in ComfyUI/models/diffusion_models.
• qwen3vl_4b_fp8_scaled.safetensors in ComfyUI/models/text_encoders.
• qwen_image_vae.safetensors in ComfyUI/models/vae.
• Krea 2 AnyPaint LoRA.

No custom sampler and no final source composite are required.

Nodes

Krea2 AnyPaint Prepare

Takes a source image, optional arbitrary mask, and four padding values. White mask pixels and all padded canvas pixels are generated; black pixels are preserved. The node outputs:

• a 384px semantic reference for Krea 2 reference attention and Qwen3-VL;
• the full-resolution known canvas;
• generated and preserved masks;
• aligned canvas dimensions.

Use the MASK output from ComfyUI's Load Image Mask Editor directly. For inpainting, keep all padding at zero. For outpainting, add space on any side. Both can be combined in one request.

Krea2 AnyPaint Encode

Encodes the prompt/reference and returns a standard ComfyUI LATENT containing the known image plus a token-aligned noise_mask. ComfyUI's sampler applies the same timestep-matched preservation used by the Diffusers reference pipeline:

known_at_sigma = sigma * initial_noise + (1 - sigma) * known_latent

Krea2 AnyPaint Model Patch

Registers the semantic reference over the complete target grid and precomputes its isolated reference K/V cache. Connect this node after Load LoRA and before KSampler.

Workflow

Drag krea2_anypaint_workflow.json into ComfyUI. The important wiring is:

Load Image (image + mask) -> AnyPaint Prepare
AnyPaint Prepare + CLIP + VAE -> AnyPaint Encode
Load Diffusion Model -> Load LoRA -> AnyPaint Model Patch -> KSampler
AnyPaint Encode.latent -> KSampler.latent_image
KSampler -> VAE Decode -> Save Image

Recommended Krea 2 Turbo settings: 8 steps, Euler, simple scheduler, CFG 1.0, LoRA strength 1.0, VLM reference enabled, K/V cache enabled.

This graph was validated end to end with the three linked Comfy-Org model files. The preprocessing, mask convention, reference placement, sigma schedule, and per-step known-region replacement match the Diffusers example and the DeepMachine backend. Quantized runtimes may differ at the pixel level from the portable BF16 example.

The output is the raw model decode. Do not add the old registered-outpaint composite node: AnyPaint preserves known pixels during every denoising step.
