DGX Spark’s 64GB model runs 100B models locally, then scales to 200B
NVIDIA’s new 64GB DGX Spark lets developers run models and agents privately on-device, without sending every task to the cloud. It arrives with DGX OS and NVIDIA’s AI software stack, supporting models up to 100 billion parameters, plus runtimes including Ollama, vLLM and PyTorch. Connect two units with a cable and Sync pools 128GB of memory for models up to 200 billion parameters, with up to 1.7x performance in NVIDIA’s Qwen 3.8 27B test.
