This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Yes, NVIDIA DGX Spark 128GB can run Mistral Nemo 12B with a C grade (Runs well). Expected decode speed: 24.1 tok/s.
Mistral Nemo 12B (12B parameters) requires approximately 24.0 GB of memory with Q4_K_M quantization.
The recommended quantization for Mistral Nemo 12B is Q4_K_M, which balances quality and memory efficiency.
On NVIDIA DGX Spark 128GB, Mistral Nemo 12B achieves approximately 24.1 tokens per second decode speed with a time-to-first-token of 8048ms using Q4_K_M quantization.
For coding workloads, Mistral Nemo 12B on NVIDIA DGX Spark 128GB receives a C grade with 24.1 tok/s and 128K context.
On NVIDIA DGX Spark 128GB, Mistral Nemo 12B can safely use up to 128K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
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.
