Google has added the option of Nvidia GPUs to its AI Platform as part of an overhaul of the as a service platform. As Google explains, "ML models are so complex that they only run with acceptable latency on machines with many CPUs, or with accelerators like NVIDIA GPUs. This is especially true of models processing unstructured data like images, video, or text." Which would be why the service's one current generally available option of one vCPU, 2GB of RAM, and no GPU support seems a little bare bones – though it does support all types of models artifacts, with a maximum model size of 500MB. This basic tier is now joined by a beta option of 4 vCPUs.
