NVIDIA DGX Spark 是全球首款桌面级 AI 超级计算机，
在 150×150×50.5 mm 机身内集成 Grace Blackwell 超级芯片、128 GB 统一内存和 1000 AI TOPS 算力，
可在本地完成 2000 亿参数大模型的原型、微调与推理，并能无缝扩展至云端或数据中心。
NVIDIA DGX Spark™ belongs to a new class of computers designed from the ground up to build and run AI. Powered by the NVIDIA GB10 Grace Blackwell Superchip, DGX Spark delivers up to 1, 000 AI TOPS1 of performance to power AI workloads. With 128 GB of coherent unified system memory, developers can experiment, fine-tune, or inference the latest generation of reasoning AI models from DeepSeek, Meta, Google, and others of up to 200B parameters. Plus, NVIDIA ConnectX™ networking can connect two DGX Spark AI computers to enable inference on models up to 405B parameters.
To give developers a familiar experience, DGX Spark mirrors the same software architecture that powers industrial-strength AI factories. Using the NVIDIA DGX OS with Ubuntu Linux and preconfigured with the latest NVIDIA AI software stack, along with developer program access to NVIDIA NIM and NVIDIA Blueprints, developers can hit the ground running using common tools such as Pytorch, Jupyter, and Ollama to prototype, fine-tune, and inference on DGX Spark and seamlessly deploy to DGX Cloud or any accelerated data center or cloud infrastructure.
