What the DeepSeek-V4-Flash-0731 numbers mean
The fastest verified result on our board is 92.1 output tok/s on an CMP 170HX x4 at FP8 with a 487713-token context. That is about 10.9 ms per generated token — 500 tokens takes roughly 5.4 seconds. Prompt processing on the same record runs at 163277.9 tok/s, so a 2,000-token prompt is read in about 0.0 seconds. Across the 7 records we hold for this model the range is 18.0–185.6 tok/s on 6 GPUs, because quantisation, context length and the engine build all move the number.
How much VRAM does DeepSeek-V4-Flash-0731 need?
DeepSeek-V4-Flash-0731 has 304.0B parameters. These estimates use the same formula as the VRAM calculator: weights, plus about 15% for a moderate-context KV cache and runtime overhead, plus a small engine floor.
| Quantisation | Estimated VRAM | Smallest card that fits |
|---|---|---|
| Q4_K_M (4-bit) | 197.4 GB | multi-GPU or CPU offload |
| Q8_0 (8-bit) | 372.2 GB | multi-GPU or CPU offload |
| FP16 (16-bit) | 700.0 GB | multi-GPU or CPU offload |
