Jibs Qwen workflow uses a custom-trained Wan VAE to remove the hash/grid lines visible in Qwen outputs.

Here is the GitHub for nodes: https://github.com/spacepxl/ComfyUI-VAE-Utils?tab=readme-ov-file
and the Custom Wan/Qwen VAE model: https://huggingface.co/spacepxl/Wan2.1-VAE-upscale2x/blob/main/Wan2.1_VAE_upscale2x_imageonly_real_v1.safetensors

V6 a Qwen 2512 Version of Jib Mix Qwen.

+ Has better fine details than previous versions.

+ Less of a same face issue.

+ Less nosie artifacts.

- Not quite as good at NSFW as V5. (You can use my NSFW lora to bring it back: https://civarchive.com/models/1943554/jibs-qwen-nudity-fixer-lora)
- Not quite as fine good details as Base Qwen 2512

More European faces and fewer Asian by default.

The Pruned Model nf4 (13.91 GB) is actually a Q5_0.GGUF

V5 -More realistic, less plastic skin by default, with more imperfections.
My Skin detail/imperfections lora can be used to add more or even help remove them if used at a negative weight.

The Version 5 Q5. GGUF (marked nf4)

V4 - Much more natural pretty faces (Much better at Asian faces), less noise, cleaner (slightly less photographic look by default but adding LORAs can make that stronger again)

NEW: The fp8_e5m2 model is twice as fast as the Q5.GGUF on my 3090.

There is a Q5 .GGUF (marked nf4)

Tune for Clownshark dpmpp_3s/Bong_tangent sampler this time instead of Euler_ancestral/Linier_ Quadratic.

V3- Important I have uploaded 2 different versions of this model:
High Noise version (marked fp16) that I think is better at lower steps and single stage workflows (but can sometime show grid/scan lines).
Lower noise version (marked fp32) That makes cleaner/less noisey images on the first gen but is better suited to 2 stage Hi-res fix workflow (this is my preferred method)

There is a Q5 .GGUF (13.91 GB) that is the Higher Noise version

The Q6 .GGUF (15.6 GB) is a lower noise realistic skin version.

Small Q5 .GGUF (13.91) is a lower noise realistic skin version.

V2 - I tried to fix the big bobble heads from the previous versions. It is better but they can still be a bit big sometimes.

The V2 fp8 model listed is now actually a Q8 .GGUF (Thanks to export_tank_harmful for the conversion when mine was broken)

V1 - Adds a more photorealistic/amateur look to Qwen.

The fp8 model listed is now actually a Q6_k .GGUF

and has fewer grid lines than the fp8 (But I still recommend the fp16 with ram offloading, for better quality)
