Can you run DeepSeek V4 Flash DSpark locally?
DeepSeek V4 family · Jun 2026 (DSpark attach) · 284B parameters (13B activated per token) · Hugging Face model card
DeepSeek V4-Flash-DSpark is not a new model (official README): it is the Flash checkpoint with a speculative-decoding module attached. Config architecture matches Flash (deepseek-ai/DeepSeek-V4-Flash-DSpark@62af8fffb2f7030cac4de2f0169f5b8d1101b646): 43 layers, 284B/13B, 256 experts × 6, 1M context, MIT. safetensors.total=165,265,454,782 (smaller than Flash instruct dump; do not treat that byte count as a new param count). Measured tok/s: not published here.
Minimum: Same as V4-Flash: 1× B200 192GB (Q4_K_M ~187 GB, calculated from 284B resident) · Recommended: Same as V4-Flash plus DSpark speculative decoding enabled at serve time
How much VRAM does DeepSeek V4 Flash DSpark need at each quantization?
DeepSeek V4 Flash DSpark needs 187.8 GB of VRAM at Q4_K_M. The table below lists weights-only size and total VRAM including overhead for each common quantization level with 4k and 32k token contexts.
| Quantization | Bits / weight | Weights only | Total + KV @4k ctx | Total + KV @32k ctx |
|---|---|---|---|---|
| Q4_K_M | 4.8 | 170.4 GB | 187.8 GB | 190.3 GB |
| Q5_K_M | 5.7 | 202.4 GB | 223.0 GB | 225.5 GB |
| Q6_K | 6.6 | 234.3 GB | 258.1 GB | 260.6 GB |
| Q8_0 | 8.5 | 301.8 GB | 332.3 GB | 334.8 GB |
| FP16 | 16 | 568.0 GB | 625.2 GB | 627.7 GB |
Official: not a new model. Same Flash arch keys. VRAM follows 284B resident, not safetensors.total/1e9.
Method: weights = parameters × bits-per-weight (Q4_K_M ≈ 4.8, Q5_K_M ≈ 5.7, Q6_K ≈ 6.6, Q8_0 ≈ 8.5, FP16 = 16), plus 10% loading overhead, plus KV cache from the verified architecture config (43 layers, 1 KV heads, 512 head dim).

Needs 2+ GPUs to run DeepSeek V4 Flash DSpark
One of these cards is too small on its own, but a pair (tensor or pipeline parallel, ~90% efficiency) covers the 187.8 GB requirement. See our multi-GPU guide for setup.
| GPU | VRAM | Bandwidth | Type | |
|---|---|---|---|---|
| H200 SXM | 141 GB ×2 | 4800 GB/s | Data Center GPU |
Can a Mac run DeepSeek V4 Flash DSpark?
Yes — these Apple Silicon machines fit DeepSeek V4 Flash DSpark at Q4_K_M, since macOS lets the GPU use about 75% of unified memory. Generation speed is bound by memory bandwidth, so the GB/s column matters as much as capacity.
| Apple Silicon | Unified memory | Usable by GPU (~75%) | Bandwidth |
|---|---|---|---|
| M3 Ultra (Mac Studio, 256 GB) | 256 GB | 192 GB | 819 GB/s |
Which pre-built systems can run DeepSeek V4 Flash DSpark?
These mini PCs and workstations from our database fit DeepSeek V4 Flash DSpark at Q4_K_M. Usable-memory figures are conservative: Windows shares about half of system RAM with the GPU by default (Linux can expose more), macOS lets Apple Silicon GPUs use about 75% of unified memory, and Linux unified-memory systems such as GB10 expose roughly 90%. Generation speed is bound by memory bandwidth, so compare the GB/s column before buying.
| System | Type | Memory | Usable for AI | Bandwidth | GPUs |
|---|---|---|---|---|---|
| HP Z8 Fury G5 (4x RTX 6000 Ada) | Workstation | 192 GB | 192 GB | 960 GB/s | 4 |
