Thank you, I have tried this option, but with the same source and the same style, 2 generated images are differents.
The command line used is :
gmic.exe output_0009.png modele\11.jpg srand 0 +fx_stylize 1,4,0,0,0.5,2,3,0.5,0.1,1,5,0,0.7,1,0,1,0,5,5,7,1,30,1000,2,1.85,0 k[2] -output result01.png
and
gmic.exe output_0009.png modele\11.jpg srand 0 +fx_stylize 1,4,0,0,0.5,2,3,0.5,0.1,1,5,0,0.7,1,0,1,0,5,5,7,1,30,1000,2,1.85,0 k[2] -output result02.png
May be a parameter in the fx_stylize option change an other random parameter…
