Single workflow with preconfigured profiles - no need to re-enter sampler parameters and jump between workflows.

Existing profiles: Full, Dev and Fast fp8, Flux fp8, any single XL.

Quickly create your own profiles - copy existing one and replace 2 or 3 values.

Simple upscale, Iterative upscale, Face and Hand detailers, UltimateSD - it's possible to choose different checkpoint for them, for example generate with HiDream and upscale with your favourite XL checkpoint.

I2I and Inpainting - toggle corresponding encoders, optionally resize input image.

Save results with Civitai-compatible metadata.

Every feature is toggleable with rgthree nodes.

Shortcuts (keybindings) for quick navigation:

1 - main area (select resolution, input prompts, toggle features, input upscale denoise)

2 - optional checkpoint selector for post-work - upscale and detailers; upscales

3 - detailers and UltimateSD

4 - XL checkpoint selector and VAE override if not baked in

5 - HiDream profiles
