Blurry image with Flux Dev [SOLVED]

[olivbrau]

Hi, here is my command (CPU backend) :

sd --diffusion-model .\flux_dev\flux1-dev-q4_0.gguf --clip_l .\flux_dev\clip_l.safetensors --vae .\flux_dev\ae.safetensors --t5xxl .\flux_dev\t5xxl_fp16.safetensors --sampling-method euler --steps 20 -H 512 -W 512 -t 20 -p "a lovely cat"

and here is the result : the cat seems very nice and realistic, but totally blurry

Did I miss something ? Does Flux dev need more steps ?
Thanks for your help !

Can you check with --cfg-scale set to 1 ?
As stated in the docs https://github.com/leejet/stable-diffusion.cpp/blob/master/docs/flux.md#run

Ah yes, flux really don't handle CFG well.

[Green-Sky]

Hm yea, we might want to think about setting defaults for some more values like cfg-scale, based on model detected.
We will need to communicate that to the user though.

You were right, I didn't read well the instructions. With 1.0, here is the result (the picture is exceptionally well done and realistic, I'm sure because there are a lot of cats in training images !)
