city96/FLUX.2-dev-gguf

This is a direct GGUF conversion of black-forest-labs/FLUX.2-dev.

The model files can be used in ComfyUI with the ComfyUI-GGUF custom node. Place the required model(s) in the following folders:

Type	Name	Location	Download
Main Model	flux2-dev	ComfyUI/models/diffusion_models	GGUF (this repo)
Text Encoder	Mistral-Small-3.2-24B-Instruct-2506	ComfyUI/models/text_encoders	Safetensors / GGUF
VAE	flux2 VAE	ComfyUI/models/vae	Safetensors

Example outputs - sample size of 1, not strictly representative

Notes

[!NOTE] As with Qwen-Image, Q5_K_M, Q4_K_M, Q3_K_M, Q3_K_S and Q2_K have some extra logic as to which blocks to keep in high precision.

The logic is partially based on guesswork, trial & error, and the graph found in the readme for Freepik/flux.1-lite-8B (which in turn quotes this blog by Ostris)

As this is a quantized model not a finetune, all the same restrictions/original license terms still apply.
