Breakthrough release: Launched in October 2025, DGX Spark is NVIDIA’s most compact DGX ever—just 18.5L in volume, quiet operation, and lower power draw (480W typical).
Grace Blackwell GB10 inside: Central to Spark is the new GB10 superchip—a CPU+GPU marvel co-designed with MediaTek, offering up to 20x faster AI training than last year’s desktop-class hardware.
Performance highlights: Early benchmarks show full GPT-3 finetunes in under an hour, stable diffusion at 80+ images/minute, and real-time multimodal inference for speech, vision, and language stacking.

Tiny powerhouse: Desktop footprint, near-silent cooling, and full software stack (DGX OS, CUDA, TensorRT, Triton).
Edge AI and enterprise ready: PCIe Gen5 slots, dual 100Gb Ethernet, and latest NVMe. Easily moved from lab to office to edge deployment in factories or research centers.
Runs big models locally: GPT-4, Llama 3, and Sora-sized video models can now be tuned, inferenced, and even multi-user scheduled on-premises—no cloud required.
Security and privacy: All local, with full TPM, zero-knowledge modules, and direct admin controls for compliance-heavy industries.

Startups building generative AI apps, vision tools, or custom LLMs.
Academia, scientists, and edge deployment pioneers—run large models without waiting for cloud queue slots.
SMEs and creative studios wanting server-grade AI, but with plug-and-play simplicity.
