Powered by the NVIDIA GB10 Grace Blackwell Superchip, NVIDIA DGX Spark delivers up to 1 petaFLOP (FP4) of AI performance in a powerefficient, compact workstation. With the NVIDIA AI software stack preinstalled and 128 GB unified memory, developers can prototype, finetune, and inference reasoning LLMs (DeepSeek, Meta, NVIDIA, Google, Qwen) with up to 200B parameters locallyideal for generative AI, RAG, multimodal, and agentic AI workflows.
Feature
Up to 1 petaFLOP (FP4) with Grace Blackwelloptimized for LLM inference, finetuning, prompt engineering, and agent frameworks.
- 128 GB coherent unified system memory
Run 200Bparameter models locally with unified LPDDR5x memory for zerocopy data access and fast context handling.
- NVIDIA ConnectX networking
ConnectX enables pairing two DGX Spark systems to handle 405Bparameter workloadsscalable multinode AI experiments.
Fullstack generative AI: NVIDIA NIM microservices, CUDA, Triton Inference Server, TensorRTLLM, toolchains, libraries, and pretrained models.
