FLUX.1 Dev is a quantized version of the black-forest-labs/FLUX.1-dev text-to-image model provided in GGUF format on Hugging Face. It enables the 12-billion-parameter model to run on a range of hardware by offering multiple quantization levels that reduce file size and memory requirements while preserving the original non-commercial license terms.
The repository supplies GGUF files at bit depths from 2-bit to 16-bit. Specific variants include Q2_K at 4.03 GB, Q3_K_S at 5.23 GB, Q4_K_S at 6.81 GB, Q4_0 at 6.79 GB, Q4_1 at 7.53 GB, Q5_K_S at 8.29 GB, Q5_0 at 8.27 GB, Q5_1 at 9.01 GB, Q6_K at 9.86 GB, Q8_0 at 12.7 GB, and F16 at 23.8 GB. These quantized models are not finetunes and therefore inherit all restrictions from the base FLUX.1-dev license, which is designated as a non-commercial license.
It integrates with the ComfyUI-GGUF custom node. Model files are placed in the ComfyUI/models/unet directory, with further setup details available in the associated GitHub readme. The page also references a chart that outlines the characteristics of each quantization type.
The model belongs to the class of text-to-image generation tools within the image-generation domain. It has recorded 119,887 downloads in the last month. No inference providers currently host it, and hardware compatibility details require login to view.
FLUX.1 Dev sits in PulseGate's Image generation category. It focuses on running the large FLUX.1-dev text-to-image model efficiently on consumer hardware with reduced memory requirements. FLUX.1 Dev is an open-source project aimed at AI developers and local AI users. The project is open source (Apache-2.0). FLUX.1 Dev is available on the web and API.
It is developed by city96, and the product first shipped in 2024. The project is developed in the open on GitHub with 3.8k stars. PulseGate's similarity index places it among 5 comparable tools. Among its 3 catalogued features are GGUF quantization, comfyUI support, and multiple bit-widths.
