Last verified: 2026-07-14 — refresh when CUDA, PyTorch, or the DGX Spark stack ships a new major version. Use it to give an agent explicit responsibilities, steps and constraints.

DGX Spark ships a GB10 Grace Blackwell chip: aarch64 CPU, SM121 GPU, 128GB unified memory, CUDA 13. This is a narrower and younger platform than a standard x86 CUDA 12 box, so package selection and ABI matching matter more than usual — the wheel ecosystem for aarch64 + CUDA 13 is. Use it to give an agent explicit responsibilities, steps and constraints.
