Can I run DeepSeek V3 on Nvidia DGX Spark (128GB)?
No. DeepSeek V3 needs ~383.7 GB even at Q4_K_M, but Nvidia DGX Spark (128GB) only has ~112 GB usable.
Needs ~383.7 GB even at Q4_K_M, but only ~112 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 271.7 GB: DeepSeek V3 needs roughly 383.7 GB at Q4_K_M and Nvidia DGX Spark (128GB) leaves only about 112 GB usable for a model. No single tracked device has enough memory; DeepSeek V3 needs a multi-GPU or high-memory rig.

FAQ
Can Nvidia DGX Spark (128GB) run DeepSeek V3?
No. DeepSeek V3 needs ~383.7 GB even at Q4_K_M, but Nvidia DGX Spark (128GB) only has ~112 GB usable.
How much memory does DeepSeek V3 need?
Nvidia DGX Spark (128GB) does not have enough memory. At Q4_K_M the weights are ~376.65 GB; with KV cache and runtime overhead, budget ~383.7 GB at a 4k context. It is a Mixture-of-Experts model (671B total / 37B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run DeepSeek V3 on Linux?
Ollama for a simple setup; vLLM for the most speed. vLLM shines for multi-user serving/throughput. For a single local chat, Ollama or llama.cpp is simpler and lighter.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
