More large AI models now fit on two DGX Spark systems
Connecting two systems with a cable provides about 250GB of usable memory for roughly $7,000–$8,000. That is enough to run several powerful models locally in 4-bit form. For a long time, the main choices around this size were GLM 4.5/4.6/4.7 (194GB), Qwen 3.5 397B (210GB), and older MiniMax models.
Over the past three months, MiniMax M2.7 (131GB), (160GB), and Xiaomi MiMo 2.5 (181GB) joined the list, followed by StepFun 3.7 Flash (129GB) and Tencent Hy3 (182GB). Before spending thousands on the hardware, the practical advice is to test the same models on for about $7.
