Can the DGX Spark (GB10) run Phi-4 Mini?

Yes. Phi-4 Mini fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 4.3 GB needed), running at an estimated 63 tok/s. There's room for up to FP16 if you want higher quality.

Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the DGX Spark (GB10)'s 273.2 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked

Quick answers

Can the NVIDIA DGX Spark (GB10) run Phi-4 Mini?

Yes. Phi-4 Mini fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 4.3 GB needed), running at an estimated 63 tok/s. There's room for up to FP16 if you want higher quality.

How much VRAM does Phi-4 Mini need?

About 2.5 GB of weights at Q4_K_M, 4.5 GB at Q8_0 and 6 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.

How fast is Phi-4 Mini on the DGX Spark (GB10)?

Roughly 63 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the DGX Spark (GB10)'s 273.2 GB/s memory bandwidth.
