[Bug] - SeFi Image doesn't load - Mage flow generate garbage with Vulkan

[JohnLoveJoy]

System Specs:

Windows 10
iGPU Vega.
Latest drivers.

Unfortunately, my dGPU has died, so right now I can't test it on another GPU architecture.

Debug info:

ImageGen Init - Load Model: E:\A.KreaTurbo\MageFlow_Q8.gguf
With Custom VAE: E:\A.KreaTurbo\VAE_MG.safetensors
With Custom T5-XXL Model: E:\A.KreaTurbo\Qwen3VL-4B-Instruct-Q4_K_M.gguf
Conv2D Direct for VAE model is enabled
Backend assignment: "CLIP=CPU"

Mage Flow. Vulkan - I tested with FA on and off; it makes no difference.

Mage Flow - CPU:

More info for debug:
ImageGen Init - Load Model: E:\A.KreaTurbo\MageFlow_Q8.gguf
With Custom VAE: E:\A.KreaTurbo\VAE_MG.safetensors
With Custom T5-XXL Model: E:\A.KreaTurbo\Qwen3VL-4B-Instruct-Q4_K_M.gguf
Conv2D Direct for VAE model is enabled
Backend assignment: "CLIP=CPU,VAE=CPU"

And SeFi Image... It just won't load, no matter what files I use.

Error: Could not load image model: E:\Sefi_IMAGE\SeFi-5B-Base-Q5_K_M.gguf

You did not mention the KoboldCpp version, can you confirm this is the latest release 1.118?

Yeah, the latest version. If it were an older one, it wouldn't even load MageFlow tbh.

@JohnLoveJoy for SeFi, did you get your SeFi image model from here? https://huggingface.co/koboldcpp/imgmodel/tree/main/SeFi-Image-5B-Turbo
If not, please try download and load these 3 files.

As for mage flow, it does seem like a vulkan specific issue, as it works on CPU and CUDA. I'll see if there's a workaround.

Yes, I can confirm that it works with that file.

Doesn't seem to be a general Vulkan issue, either; it's working fine on my own Vega iGPU (Linux + radv, clip on GPU):

RX 7600 XT	Ryzen 3400G

Edit: could be related to the quantization; this test was with mage-flow-turbo.safetensors + Qwen3VL-4B-Instruct-Q8_0.gguf .

It could simply still be a bug in the proprietary driver.

I am getting bad results for mage flow myself on vulkan too. Almost like its generating unrelated images
