What the DeepSeek-V4-Flash-Vision-Exp numbers mean
The fastest verified result on our board is 179.5 output tok/s on an RTX PRO 6000 Blackwell x2 at FP8 with a 1048576-token context. That is about 5.6 ms per generated token — 500 tokens takes roughly 2.8 seconds. Prompt processing on the same record runs at 15057.6 tok/s, so a 2,000-token prompt is read in about 0.1 seconds. Peak VRAM was measured at 183.1 GB.
How much VRAM does DeepSeek-V4-Flash-Vision-Exp need?
DeepSeek-V4-Flash-Vision-Exp has 305.0B 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) | 198.1 GB | multi-GPU or CPU offload |
| Q8_0 (8-bit) | 373.5 GB | multi-GPU or CPU offload |
| FP16 (16-bit) | 702.3 GB | multi-GPU or CPU offload |
