ComfyUI-GigaHires

Workspace for a new high-quality, high-performance hires-fix / upscale custom node for ComfyUI.

Current status:

• local research notes captured from ComfyUI core and local ReForge source
• helper nodes implemented for the workflow-first direction:
  • GigaHires Latent Upscale
  • GigaHires Image Upscale
  • GigaHires Refine Pass
• coordinator nodes still available:
  • GigaHires V1
  • GigaHires Easy

Recommended direction:

• use the helper-node workflow
• keep normal pass, upscale, and refine visibly separate
• later collapse that layout into a subgraph with only the important face controls exposed

Helper nodes:

• GigaHires Latent Upscale
  • latent-space upscale with scale_by or exact target size
• GigaHires Image Upscale
  • image-space upscale with scale_by or exact target size
  • accepts an UPSCALE_MODEL input or internal model dropdown
• GigaHires Refine Pass
  • explicit second-pass sampler stage on the already-upscaled latent

Coordinator nodes:

• GigaHires V1
  • single post-sampler hires coordinator with most knobs exposed
• GigaHires Easy
  • simplified wrapper kept around for quick experiments, not the main UX direction
