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.
