Why this fits

96 vCPU and 900 GiB RAM — sized for workloads the default GitHub-hosted runners can't comfortably host, all on your own Azure account.
A100 × 8 — large ML CI, RDMA interconnect for distributed tests.
NVIDIA A100 40GB for PyTorch / JAX and other CUDA workloads, with drivers + CUDA pre-baked in the runner image.
