cmake .. -DGGML_CUBLAS=ON -DCMAKE_CUDA_COMPILER=/opt/cuda/bin/nvcc
to use my NVIDIA GeForce RTX 2060 SUPER.
I have converted the model to use FP16.
With these choices, the time per iteration is between 8.5 s and 9 s and the total time for making an image is around 200 s.

Seeing the times reported by other people, it seems that using the GPU with GGML, instead of the CPU, still provides a speed improvement, but it is small.
Nevertheless, I have appreciated that after following exactly the instructions of this project everything was up and running after a few minutes and it could be tested.
Past attempts to install all the environment needed to run such models have required much more work.
