This repo contains a variant of QWEN's QWEN-IMAGE, the state-of-the-art generative model with extensive and (image/)text-to-image &/or instruction/control-editing capabilities.

To make these cutting edge capabilities more accessible to those constrained to low-end consumer-grade hardware, we've quantized the DiT (Diffusion Transformer) component of Qwen-Image to the 4-bit NF4 format using the Bits&Bytes toolkit.
This optimization was derived by us directly from the BF16 base model weights released on 08/04/2025, with no other mix-ins or modifications to the DiT component.
NOTE: Install bitsandbytes prior to inference.

QWEN-IMAGE is an open-weights customization-friendly frontier model released under the highly permissive Apache 2.0 license, welcoming unrestricted (within legal limits) commercial, experimental, artistic, academic, and other uses &/or modifications.

To help highlight horizons of possibility broadened by the QWEN-IMAGE release, our quantization is bundled with an "Abliterated" (aka de-censored) finetune of Qwen2.5-VL 7B Instruct, QWEN-IMAGE model's sole conditioning encoder (of prompts, instructions, input images, controls, etc), as well as a powerful Vision-Language-Model in its own right.

As such, our repo saddles a lean & prim NF4 DiT over the Qwen2.5-VL-7B-Abliterated-Caption-it by Prithiv Sakthi (aka prithivMLmods).

NOTICE:

Do not be alarmed by the file warning from the ClamAV automated checker.
It is a clear false positive. In assessing one of the typical Diffusers-adapted Safetensors shards (model weights), the checker reads: The following viruses have been found: Pickle.Malware.SysAccess.sys.STACK_GLOBAL.UNOFFICIAL
However, a Safetensors by its sheer design can not contain suchlike inserts. You may confirm for yourself thru HF's built-in weight/index viewer.
So, to be sure, this repo does not contain any pickle checkpoints, or any other pickled data.

TEXT-TO-IMAGE PIPELINE EXAMPLE:

This repo is formatted for usage with Diffusers (0.35.0.dev0+) & Transformers libraries, vis-a-vis associated pipelines & model component classes, such as the defaults listed in model_index.json (in this repo's root folder).
Sourced/adapted from the original base model repo by QWEN. EDIT: We've confronted some issues with using the below pipeline. Will update once reliable adjustments are confirmed.

Next to it hangs a poster showing a beautiful Chinese woman, and beneath the poster is written "π≈3.1415926-53589793-23846264-33832795-02384197". Ultra HD, 4K, cinematic composition'''
