NVIDIA unveils deskside DGX AI systems for local model development
US chipmaker NVIDIA has introduced desk-side DGX Spark and DGX Station systems at CES, enabling developers to run large-scale artificial intelligence models locally without relying on data centres.
NVIDIA said the new DGX Spark and DGX Station systems are designed to support local development, fine-tuning and inference of open and frontier AI models, ranging from 100 billion parameters on DGX Spark to one trillion parameters on DGX Station.
The company said both systems are built on its Grace Blackwell architecture and feature large unified memory, petaflop-level AI performance and preconfigured NVIDIA AI software with CUDA-X libraries.
According to NVIDIA, the architecture supports NVFP4 precision, which can compress models by up to 70% and improve performance. It added that software optimisations, including llama.cpp, deliver around a 35% performance uplift and faster model loading on DGX Spark.
DGX Station is powered by the GB300 Grace Blackwell Ultra superchip and includes 775 gigabytes of coherent memory with FP4 precision. NVIDIA said the system can run models with up to one trillion parameters, including Kimi-K2 Thinking, DeepSeek-V3.2, Mistral Large 3, Meta Llama 4 Maverick, Qwen3 and OpenAI gpt-oss-120b.
At CES, NVIDIA demonstrated large language model pretraining at 250,000 tokens per second, large-scale data visualisation and text-to-knowledge graph generation. The company also showed DGX Spark accelerating video generation workloads and running a local CUDA-based coding assistant.
