DeepSeek V4 Flash: Bringing Frontier AI to the Home

Running a near-frontier AI model at home used to be unthinkable, but DeepSeek V4 Flash has changed that. Using two NVIDIA DGX Spark units connected with a high-speed cable, a home setup achieved 88.6% on GPQA Diamond — a PhD-level science benchmark — matching scores that only top commercial AI models reached six months ago. The model's efficient architecture, activating only 13 billion of its 284 billion parameters per token, makes this possible on consumer hardware.
