Krea 2 Turbo Image Generator

This Space runs Krea 2 Turbo through headless ComfyUI execution. It provides:

• Text-to-image generation.
• Instruction-based image editing with an optional second reference image.
• Krea 2 Identity Edit v1.2 conditioning for the edit mode.
• Two selectable custom Krea 2 Turbo checkpoints.
• An option to download and use a custom base checkpoint from any accessible Hugging Face repository.
• A catalog of Krea 2 LoRAs with signed weight controls and search/filtering.
• Custom LoRAs from any accessible Hugging Face repository.
• Seed, sampling, grounding, and reference-fidelity controls.
• PNG metadata and portable JSON settings profiles.

Models

The text encoder and VAE are downloaded from the ungated Comfy-Org/Krea-2 mirror. The base-model selector provides both checkpoints from mpasila/Krea-2-Models:

Choose Custom Hugging Face base model in the base checkpoint selector to provide a repository, relative model filename, and optional revision. Supported files use .safetensors, .ckpt, .pt, or .bin extensions. The checkpoint is downloaded lazily into ComfyUI's managed diffusion-model directory and cached in a stable repository/revision namespace. Private repositories require the HF_TOKEN or HUGGINGFACE_HUB_TOKEN environment variable.

Edit mode also downloads krea2_identity_edit_v1_2.safetensors from conradlocke/krea2-identity-edit. The edit nodes come from ComfyUI-Krea2Edit.

LoRAs

The built-in catalog is loaded from krea2_loras.json and downloaded lazily from mpasila/Krea-2-LoRAs. A weight of zero disables an entry. Enabled catalog entries are applied in the order listed in the catalog, then custom rows are applied in their table order. Signed weights are supported for slider LoRAs.

Custom Hugging Face LoRAs use one table row per file:

Only relative model files with supported extensions are accepted. Private repositories require the HF_TOKEN or HUGGINGFACE_HUB_TOKEN environment variable. Catalog and custom LoRAs are cached under ComfyUI’s managed LoRA directory and are downloaded only when their weight is non-zero. In edit mode, the mandatory Krea 2 Identity Edit adapter remains enabled before the user LoRA chain; it is not included in the selectable catalog.

All model and adapter licenses remain applicable. Review the Krea 2 Community License Agreement and the adapter repository’s responsible-use guidance before deploying this Space. Do not use the identity-edit workflow for non-consensual or harmful impersonation of real people.

Usage

Choose text-to-image for a new image, or edit to provide a primary source image and an optional second reference. In edit mode, image order matters: the primary image is the scene/source and the second image is the subject or additional reference.

The edit workflow uses fit reference geometry. The target megapixel setting controls the output size while preserving the primary image’s aspect ratio. Lower grounding values usually follow the edit instruction more strongly; higher values usually preserve reference identity more strongly.

Generated PNGs include a krea_settings JSON object and a readable parameters field. Source image bytes are never stored in exported settings profiles. Profiles also preserve the selected checkpoint, custom base-model repository/file/revision, catalog weights, and custom Hugging Face LoRA rows.
