My favorite feature is being able to setup a container on my Linux desktop that has a GPU access and can run ML workloads for image processing whenever I turn the computer on, as my NAS (where Immich resides) is a low power machine without a dedicated GPU. They even have ROCM support, so it works even without an Nvidia GPU. Being able to spread such workloads over your local network feels like a magic that has been forgotten in an era of blackbox cloud providers.
