ComfyUI FP8 checkpoints
This repository provides ComfyUI-ready checkpoints derived from the official Microsoft Mage-Flow-Edit and Mage-Flow-Edit-Turbo weights.
Mage-Flow is not currently supported by official ComfyUI. To load and run these checkpoints, use the custom nodes and workflows from starsFriday/ComfyUI-MageFlow.
The FP8 transformer files use scaled FP8 weight storage with BF16/full-precision matrix multiplication. In the ComfyUI model loader, select weight_dtype = bf16; activation-quantized fast FP8 matrix multiplication can make the four-step Turbo checkpoint collapse into structured noise.
[!WARNING] The official Mage VAE currently produces garbled or noise-like decoded images in this ComfyUI workflow. Useflux2-vae.safetensorsfor normal image decoding.mage_vae_bf16.safetensorsis retained as the original BF16 reference checkpoint.
ComfyUI custom nodes
Use the workflows and loader/conditioning nodes from:
[starsFriday/ComfyUI-MageFlow](https://github.com/starsFriday/ComfyUI-MageFlow)
