Krea 2 Turbo — Hires + Detailer Workflow (SAM3) — v1.1 — v3.2

This ComfyUI workflow uses Krea 2 Turbo to turn a positive text prompt into an image, then can upscale it and redraw faces or text-selected regions; it can also route an existing image through correction stages and save the result as an image.

The base generator, upscaler, and Face Detailer are on by default; Hires Fix and the SAM3.1 detail and exclusion groups are off by default.

With SAM3.1 enabled, prompts such as `face:99` or `hand:99` select regions, and a detection preview shows the area to be redrawn.

Edit `Positive Prompt` in `Krea2Turbo`; enabling `Load existing image` routes a loaded image into the correction path, and saved output goes to `ComfyUI/output/Krea2Turbo/`.

The Image Comparer slider lets you compare the detailed result with the raw generation.

To start, load the workflow, edit the positive prompt, optionally add LoRAs in Power Lora Loader, and queue it.

The listed model files are `4x-UltraSharp.pth`, `bbox/face_yolov8m.pt`, `krea2_identity_edit_v1_2.safetensors`, `krea2_turbo_fp8_scaled.safetensors`, `qwen_image_vae.safetensors`, `qwen3vl_4b_fp8_scaled.safetensors`, `sam_vit_b_01ec64.pth`, and `sam3.1_multiplex_fp16.safetensors`

The listed node packs are `comfyui-freememory`, `comfyui-impact-pack`, `comfyui-impact-subpack`, `comfyui-lama-remover`, `erosdiffusion-eulerflowmatchingdiscretescheduler`, and `rgthree-comfy`.

The SAM3.1 and Identity Edit groups are off by default; using them requires `sam3.1_multiplex_fp16.safetensors` and `krea2_identity_edit_v1_2.safetensors`, respectively.

To work on an existing image, enable `Load existing image`; the instructions say base generation still runs unless you set `Krea2Turbo` steps to 1.

To increase output size, adjust the Upscaler `scale_by` setting; the instructions give `0.375` as an example.

Use Fast Groups Bypasser or Ctrl+B to toggle whole groups; bypassing a single node can leave a required input missing.

For face correction, choose Face Detailer or SAM3.1; the instructions warn that using both on faces redraws the same area twice.
