This workflow is built for creators who need to refine many images with Krea2 without opening the graph for every single file. It is the batch-oriented version of the Krea2 image refinement setup: upload a ZIP package, let the workflow extract the image range, run the same restoration chain in a loop, and collect the outputs through RunningHub. It is useful for image cleanup, style-safe retouching, thumbnail batches, character card updates, and dataset preview passes where you want consistent processing rather than one-off manual tuning.

The main model path uses `krea2_turbo_fp8.safetensors` through a UNET loader, paired with `qwen3vl_4b_fp8_scaled.safetensors` as the Krea2 CLIP/text encoder and `qwen_image_HDR_vae_fp32_comfy.safetensors` for decoding. The graph also includes a Qwen3VL processing route and an RH LLM API node, which helps generate or organize prompt guidance around the uploaded image content. The active structure-control side uses `depth-control-lora.safetensors` at strength 1.0, DA3 depth inference, Krea2ControlImageEncode, and Krea2ControlApply nodes. That means the workflow is not just doing blind upscaling: it tries to preserve the source image structure while giving Krea2 room to rebuild detail.

The batch logic is visible in the graph through RHUploadZip, RHBatchImages, RH_ExtractImage, `easy forLoopStart`, `easy forLoopEnd`, and a batch-any output collection path. The image chain uses three KSampler stages with 8 steps, CFG 1, euler/simple sampling, and denoise values around 0.95, 0.35, and 0.25. The first stage gives the model enough freedom to rebuild the image; the later stages compress the structure back and polish the final output. The workflow also includes latent resizing toward 1024 x 1024, a `4x-UltraSharp.pth` image upscale model, and a final 2048 x 2048 image scale path. I describe it as a high-resolution refinement workflow rather than a guaranteed 4K/6K pipeline, because the confirmed graph ends around a 2048-square output path.

Main features:

- Krea2 Turbo FP8 image refinement chain
- Online ZIP upload entry for batch image processing
- RHBatchImages and loop-based image extraction
- Qwen3VL-assisted prompt or image understanding route
- Qwen Image HDR VAE decode path
- Depth-control LoRA enabled at strength 1.0
- DA3 depth inference for structure guidance
- Three Krea2Control image encode/apply stages
- Three 8-step euler/simple sampler passes
- Denoise sequence around 0.95, 0.35, and 0.25
- 1024 latent refinement path
- 4x-UltraSharp upscaling stage
- Final 2048-square image scale path
- Multiple preview outputs for checking batch results
- Best suited for consistent batch cleanup and retouching

Suggested workflow:

Prepare a ZIP that only contains supported image files such as JPG, JPEG, PNG, or WEBP. Keep the first batch small, then check whether the denoise balance preserves the source subject and composition. If the output becomes too different from the original, reduce the strength of the early rebuild stage or make the prompt more conservative. If the image keeps the structure but lacks detail, focus on the later refinement and upscale stages instead of forcing more variation at the beginning.

For large batches, use the same prompt logic across the whole set and inspect several outputs before running everything. This workflow is strongest when the input images share a similar cleanup target, such as softer anime illustrations, character portraits, or concept art that needs sharper detail and more coherent texture.
