# Example Workflows
|
||
|
||
## Open directly in ComfyUI
|
||
|
||
The V11 files below are **native ComfyUI canvas workflows**, with nodes, links, widget values and canvas layout. They are not Photo Studio imports and do not need Photo Studio to run.
|
||
|
||
1. Install Krea Reference **0.5.0 or newer**, restart ComfyUI and refresh the page.
|
||
2. Download [V11 Reference starter — raw JSON](https://raw.githubusercontent.com/kgilper/krea-reference/main/example_workflows/krea-v11-reference-stack-workflow.json) or [V11 Concept Sliders — raw JSON](https://raw.githubusercontent.com/kgilper/krea-reference/main/example_workflows/krea-slider-v11-showcase-workflow.json). On a GitHub file page, use **Download raw file**; do not save the HTML page as JSON.
|
||
3. Drag the downloaded JSON onto the ComfyUI canvas, or use ComfyUI's workflow Open command.
|
||
4. Select installed Krea model files in the diffusion-model, text-encoder and VAE loaders. The saved examples use `krea2/krea2_turbo_nvfp4.safetensors`, `krea2/qwen3vl_4b_fp8_scaled.safetensors` and `krea2/qwen_image_vae.safetensors`. Folder separators vary by host. A compatible alternative model must be selected explicitly if those files are absent.
|
||
5. For the reference starter, copy the repo's `example_assets/krea-reference-examples` folder into `ComfyUI/input/krea-reference-examples`, or choose your own files in all three Load Image nodes. The assets are available in the GitHub repository; registry packages may not include them. Even the zero-strength card's connected Load Image needs a valid file. The slider showcase requires no input images.
|
||
6. Queue the workflow. Defaults are 1024×1536, eight Euler/simple steps and CFG1. The slider showcase also renders a plain comparison branch, so it runs two samplers. View the image previews and the stack reports.
|
||
|
||
Every Krea guide card, reference stack, concept card and concept stack in these V11 files is a V11 class, including negative/comparison branches. Their JSON `version: 0.4` denotes the ComfyUI canvas format, not the Krea node version. Standard Comfy nodes and shared socket types keep their usual names.
|
||
|
||
## V11 opt-in examples
|
||
|
||
- [Reference starter](krea-v11-reference-stack-workflow.json): the established reference topology with V11 classes; balance starts off. Replace the sample image filenames and select your installed models.
|
||
- [Concept Slider showcase](krea-slider-v11-showcase-workflow.json): six cards, automatic reach/budget based on active values, per-card presets/timing and a same-seed plain comparison. Start with one nonzero card. Near-zero values blend toward the plain prompt; larger changes can still reframe the subject.
|
||
|
||
See the [V11 guide](../docs/krea-v11-user-guide.md). Existing example files remain available unchanged.
|
||
|
||
|
||
## Prior-version examples
|
||
|
||
Older V9/V10/Slider V1 graphs retain their filenames for saved links. Their [workflow descriptions](../docs/previous-versions/native-workflows.md) and [versioned documentation](../docs/previous-versions/README.md) are archived separately.
|
||
|
||
The current slider showcase requires the GitHub update containing **Slider scaling mode** (added after registry 0.5.0). After updating and restarting ComfyUI, refresh the page. For an existing canvas, choose **automatic** on its V11 stack; missing mode fields remain manual. The report shows computed controls. Automatic ignores the manual reach/budget widgets.
