    I suggest you open a request on the llama.cpp project, since ggml (our backend library) is developed primarily there.

    As far as I know, they are the only ones with a well-optimized inference engine for NPUs (specifically XDNA2), and it’s impressive what they achieve within a TDP below 2 W. It makes me think that AMD should focus resources on ASICs and the software ecosystem for them.

    Hey, would love to have a help out. I was working on a android app to have a local quantized sdxl as a model to run.

    I tried wirh stable-diffusion.cpp, however due to it not having npu support it takes a huge amount of time. I am working on a exynos samsung processor, could you suggest any other alternative which i can use.
    Anyways thanks for the reply.
