DeepSeek R1 0528 Qwen3 8B needs ~31.6 GB VRAM. NVIDIA DGX Spark 128GB has 0 MB. With F16 quantization, expect ~14 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 DeepSeek R1 0528 Qwen3 8B at F16 quantization (Runs well). The recommended Q4_K_M requires 7.0 GB which exceeds available memory, but at F16 it needs only 31.6 GB. Expected decode speed: 14.0 tok/s.
DeepSeek R1 0528 Qwen3 8B (8B parameters) requires approximately 7.0 GB at Q4_K_M quantization. On NVIDIA DGX Spark 128GB, it fits at F16 using 31.6 GB.
The recommended quantization is Q4_K_M, but on NVIDIA DGX Spark 128GB the best fitting quantization is F16, which uses 31.6 GB.
On NVIDIA DGX Spark 128GB, DeepSeek R1 0528 Qwen3 8B achieves approximately 14.0 tokens per second decode speed with a time-to-first-token of 13845ms using F16 quantization.
For coding workloads, DeepSeek R1 0528 Qwen3 8B on NVIDIA DGX Spark 128GB receives a F grade with 6.0 tok/s and 4K context.
On NVIDIA DGX Spark 128GB, DeepSeek R1 0528 Qwen3 8B can safely use up to 1.3M 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.
