【FLUX】KONTEXT — v2.0

Use this ComfyUI workflow to edit images with FLUX Kontext: provide a written prompt and an input image, then generate an edited image with optional tiled upscaling.

Load the model, write a prompt, and generate an image; the workflow also supports image-to-image generation.

The workflow contains eight nodes and a built-in SeedVR2 tiled upscaler.

Provide a written prompt and an input image for image-to-image editing.

Saved images include all generation parameters as embedded metadata.

In ComfyUI, turn on “Use Nodes V2 (Vue)” in Settings, refresh the page, and then load the workflow.

The auto version can download models automatically.

Install ComfyUI-UmeAiRT-Toolkit; it is the only custom node to install and packages the upscaler, face detailer, and metadata saver.

For manual base setup, prepare `flux1-kontext-dev-fp8-e4m3fn.safetensors`, `t5xxl_fp8_e4m3fn_scaled.safetensors`, and `clip_l.safetensors`.

For manual GGUF setup, the listed choices are models `G8`, `G5`, or `G4`; CLIP `Q8`, `Q6`, `Q5`, `Q4`, or `Q3`; text encoder `ViT-L-14-TEXT-detail-improved-hiT-GmP-TE-only-HF.safetensors`; and VAE `ae.safetensors`.

Toggle the built-in SeedVR2 upscaler on or off for tiled upscaling.

Use three LoRA slots with individual on/off toggles and strength controls.

Before use, verify that `comfyui-umeairt-toolkit`, `FLUX/Kontext`, and `seedvr2_ema_7b_sharp_fp8_e4m3fn_mixed_block35_fp16.safetensors` are available.

Without ComfyUI’s Nodes 2.0 (Vue) interface, the workflow may have display problems.
