# Flux.1-dev (GGUF) — personal weights mirror

A personal mirror of the Flux.1-dev weights, quantized text encoders, and pencil-style LoRAs. Weights only — bring your own inference runtime.

> ⚠️ **Non-commercial only.** This bundle contains `black-forest-labs/FLUX.1-dev`, released under the **FLUX.1 [dev] Non-Commercial License**. The weights and any outputs derived from them may not be used for commercial purposes. The full license is in [`licenses/FLUX1dev-LICENSE.txt`](licenses/FLUX1dev-LICENSE.txt) and governs this repository as a whole.

## Attribution

- **Flux.1-dev** — Black Forest Labs. Upstream weights: [`black-forest-labs/FLUX.1-dev`](https://huggingface.co/black-forest-labs/FLUX.1-dev). License: [FLUX.1 [dev] Non-Commercial License](licenses/FLUX1dev-LICENSE.txt).
- **GGUF quantizations** — `Q5_K_S` quants of the Flux.1-dev diffusion model and T5-XXL encoder. Commonly sourced from [`city96/FLUX.1-dev-gguf`](https://huggingface.co/city96/FLUX.1-dev-gguf) and [`city96/t5-v1_1-xxl-encoder-gguf`](https://huggingface.co/city96/t5-v1_1-xxl-encoder-gguf) — verify the specific file you downloaded and update this line accordingly.
- **CLIP-L & T5-XXL encoders** — bundled by [`comfyanonymous/flux_text_encoders`](https://huggingface.co/comfyanonymous/flux_text_encoders). Their LICENSE is preserved in [`licenses/flux_text_encoders-LICENSE.txt`](licenses/flux_text_encoders-LICENSE.txt).
- **Pencil LoRAs** — third-party style LoRAs. **TODO before publishing:** add the original author(s), download URL, and the LoRA's own license terms. Some style LoRAs restrict mirroring on Hugging Face.

## Restrictions (summary, not legal advice)

By downloading or using these weights you agree that you will **not**:

- use them or their outputs for any commercial purpose;
- redistribute modified versions under a more permissive license than the original;
- remove or obscure the license files in `licenses/`;
- use them in any way that violates the FLUX.1 [dev] Non-Commercial License.

For commercial licensing of Flux.1-dev, contact Black Forest Labs directly via [https://blackforestlabs.ai/](https://blackforestlabs.ai/).

## Changelog

- _initial mirror_ — upload of locally-used weights and LoRAs.
