Can Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored run on NVIDIA DGX Spark 128GB?

Yes, NVIDIA DGX Spark 128GB can run Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored with a C grade (Runs well). Expected decode speed: 5.6 tok/s.

Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored (48B parameters) requires approximately 49.2 GB of memory with Q4_K_M quantization.

The recommended quantization for Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored is Q4_K_M, which balances quality and memory efficiency.

On NVIDIA DGX Spark 128GB, Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored achieves approximately 5.6 tokens per second decode speed with a time-to-first-token of 34607ms using Q4_K_M quantization.

For coding workloads, Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored on NVIDIA DGX Spark 128GB receives a C grade with 5.6 tok/s and 186K context.

On NVIDIA DGX Spark 128GB, Qwen3 48B A4B Savant Commander Distill 12X Closed Open Heretic Uncensored can safely use up to 186K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.

Prioritize bandwidth, not only capacity. If this workload feels slow, the next useful step is often a GPU tier with materially faster memory bandwidth rather than only a small bump in capacity.

Not always. NVIDIA DGX Spark 128GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
