Installation

Clone this repo into your custom_nodes directory.

Nodes

  • Flex Guidance: Allows you to set the guidance for the Flex.1 guidance embedder, or bypass it completly to use true CFG.
  • Flex LoRA Loader: Loads LoRAs and automatically prunes them to Flex.1 layers. It will not be perfect as Flex is heavily diverged from Flux dev and is not a direct ancenstor of it, but it should be good enough for most purposes.
  • Flex LoRA Loader (Model Only): Same as Flex LoRA Loader, but only loads the model and not the text encoder. Most Flux LoRAs do not train the text encoder.
