AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

  • This ComfyUI workflow is for FLUX UltimateSD Upscale: provide a model and a text prompt to generate an upscaled image.

Flow

  • It is described as a six-node workflow built with the UmeAiRT Toolkit for ComfyUI.

  • The UmeAiRT Toolkit is described as packaging an upscaler, face detailer, and metadata saver.

Inputs and outputs

  • Use a model and a text prompt as the main inputs; the described output is an upscaled image.

  • Manual setup lists CLIP, a text encoder, and a VAE as required files.

Setup

  • Enable ComfyUI's Nodes 2.0 (Vue) interface by turning on “Use Nodes V2 (Vue),” refreshing the page, and then loading the workflow.

  • Install ComfyUI-UmeAiRT-Toolkit through ComfyUI Manager by searching “UmeAiRT,” or use the UmeAiRT Auto-Installer.

Dependencies

  • Before using it, verify that ComfyUI-UmeAiRT-Toolkit is available.

    Suggestion

  • Also verify that 4x-AnimeSharp.pth and FLUX/Dev are available.

    Suggestion

Configuration

  • For the base variant, use flux1-dev-fp8.safetensors or flux1-dev-fp16.safetensors for the model, plus clip_l.safetensors for CLIP.

  • For the GGUF variant, the listed model and CLIP choices are Q8, Q6, Q5, Q4, and Q3.

  • Common files include t5xxl_fp8_e4m3fn.safetensors or ViT-L-14-TEXT-detail-improved-hiT-GmP-TE-only-HF.safetensors as the text encoder, plus ae.safetensors as the VAE.

Cautions

  • If Nodes 2.0 (Vue) is disabled, the workflow may have display problems.

  • No license is listed for this workflow.
