FLUX 3 Image Klein GGUF files and Mac RAM

Distilled 5.6B text-to-image and editing model with Qwen3-VL-4B-Instruct as the text encoder. The FLUX Kommunity License limits model use to non-commercial work, with an output exception below US$5,000,000 revenue.

Answer

No published Mac run with a GGUF build yet. The smallest complete GGUF download is 12.88 GB; a download that fits in memory does not prove the model runs.

FLUX Kommunity License v1.0. Commercial use: restricted. Excluded territories: none listed. Ordinary model use is non-commercial. Output generation has an exception for qualifying users below US$5,000,000 gross annualized revenue.

This is the distilled FLUX 3 Image Klein checkpoint. FLUX 3 Image Klein Base and the prompt upsampler are separate repositories and roles.

Does it fit your Mac's RAM?

Published names the exact measured machine. est. is a memory calculation. unknown means the run verdict is not established, not that the model fails.

    Official

    Formats: safetensors, gguf. Memory policy: component stages stay resident.

    Runs on the PyTorch mps device on Mac and CUDA on NVIDIA. GGUF loads through from_single_file on the model class, not the pipeline. Resident size is the sum of the weights, an upper bound.

What does the official configuration say?

"Peak GPU memory with the reference code on a B200 at 1024x1024 with the prompt upsampler off is 31 GB in BF16, 26 GB in FP8 and 25 GB in NVFP4. This is a datacenter GPU figure, not a Mac minimum."

What known issues should you check?

  • Known issue 1

    Black Forest Labs says not to use the model without a prompt upsampler. The upsampler is a separate 9B model and is not counted in the sizes here.

  • Known issue 2

    The Mac timings come from a run with other applications active and growing swap. The authors call them observations under shared load, not a speed ranking.
