Product Highlights
- Runs inference workloads with supported AI models up to 200 billion parameters using 128GB of coherent unified memory.
- Supports fine-tuning of supported models up to 70 billion parameters.
- Includes the NVIDIA AI software stack and DGX OS for local AI development and deployment workflows.
- ConnectX-7 networking can link two DGX Spark systems for supported workloads using models up to 405 billion parameters.

Compatibility Notes
DGX Spark uses an Arm-based CPU and DGX OS. Confirm that required applications, containers, libraries, and peripheral drivers support the Arm64 software environment. The 1 PFLOP figure is theoretical FP4 performance with sparsity and should not be interpreted as application-level performance for every workload.
