How much VRAM does DeepSeek V4 Flash Base need at each quantization?

DeepSeek V4 Flash Base 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.

Same Flash architecture (config identical on published arch keys). VRAM follows 284B resident.

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).

Runs DeepSeek V4 Flash Base comfortably (25%+ VRAM headroom)

Minimum GPUs that fit DeepSeek V4 Flash Base at Q4_K_M

These GPUs hold the model but leave little headroom — keep contexts short.

Needs 2+ GPUs to run DeepSeek V4 Flash Base

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.

Can a Mac run DeepSeek V4 Flash Base?

Yes — these Apple Silicon machines fit DeepSeek V4 Flash Base 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.

Which pre-built systems can run DeepSeek V4 Flash Base?

These mini PCs and workstations from our database fit DeepSeek V4 Flash Base 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.
