Ministral 3 3B Instruct 2512 needs ~20.8 GB VRAM. NVIDIA DGX Spark 128GB has 0 MB. With F16 quantization, expect ~37 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.

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 Ministral 3 3B Instruct 2512 at F16 quantization (Runs well). The recommended Q4_K_M requires 3.4 GB which exceeds available memory, but at F16 it needs only 20.8 GB. Expected decode speed: 37.3 tok/s.
Ministral 3 3B Instruct 2512 (3B parameters) requires approximately 3.4 GB at Q4_K_M quantization. On NVIDIA DGX Spark 128GB, it fits at F16 using 20.8 GB.
The recommended quantization is Q4_K_M, but on NVIDIA DGX Spark 128GB the best fitting quantization is F16, which uses 20.8 GB.
On NVIDIA DGX Spark 128GB, Ministral 3 3B Instruct 2512 achieves approximately 37.3 tokens per second decode speed with a time-to-first-token of 5192ms using F16 quantization.
For coding workloads, Ministral 3 3B Instruct 2512 on NVIDIA DGX Spark 128GB receives a F grade with 16.1 tok/s and 4K context.
On NVIDIA DGX Spark 128GB, Ministral 3 3B Instruct 2512 can safely use up to 4.0M tokens of context at F16 quantization. The model's official context limit is —, 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.
