Can I Run DeepSeek V4-Pro on NVIDIA DGX Spark?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 21 lipca 2026
No. DeepSeek V4-Pro needs 527.4 GB at 8K context (526 GB weights + 1.4 GB KV cache/overhead) at Q2 (experimental, datacenter only) and the NVIDIA DGX Spark has only 128 GB. No quantization we publish closes a gap that size.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 128 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q2 (experimental, datacenter only) on the NVIDIA DGX Spark: 8K 527.4 GB ✗ · 32K 529.1 GB ✗ · 128K 536 GB ✗. Past 8K it no longer fits 128 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Step down to a smaller size in this family — no single consumer card we track fits this one.
No compatible GPU? DeepSeek V4 on 128 GB of system RAM, CPU only: runs, but it is tight.
