DeepSeek V4 Flash DSpark
165.27 billion parameters in total, but only 20.36 billion are read for each token. That split is the whole point of the design: it costs the memory of a large model and the speed of a small one. Grouped-query attention keeps the cache small, so long contexts cost less here than on models of the same size.
Memory needed, by quantisation
At an 8k context window. Quality is our rough ranking of how much the compression costs you: anything at or above Q5 is hard to tell apart from the original in normal use.
| Quantisation | File size | KV cache | Total VRAM | Quality | What it costs you |
|---|---|---|---|---|---|
| Q8_0 | 163.54 GB | 0.01 GB | 164.4 GB | 99% | Lossless in practice. Use it when the memory is there. |
| Q6_K | 126.21 GB | 0.01 GB | 127.08 GB | 98% | Very close to Q8 for two thirds of the size. |
| Q5_K_M | 109.48 GB | 0.01 GB | 110.34 GB | 96% | The quality-first choice when Q6 will not fit. |
| Q4_K_M | 92.93 GB | 0.01 GB | 93.79 GB | 93% | The default. Best size-to-quality ratio for local use. |
| IQ4_XS | 81.77 GB | 0.01 GB | 82.63 GB | 91% | Importance-matrix 4-bit. Q4_K_S quality, smaller file. |
| Q3_K_M | 75.23 GB | 0.01 GB | 76.09 GB | 86% | Degradation starts to show. A way to fit one size up. |
| IQ3_XXS | 58.87 GB | 0.01 GB | 59.74 GB | 79% | Aggressive. Only worth it on very large models. |
What a longer conversation costs
Same model at Q4_K_M, only the context window changes. This model uses sliding-window attention, so most layers stop growing past 128 tokens and the bill flattens out.
| Context | KV cache | Total VRAM | Fits in 8 GB | Fits in 12 GB | Fits in 24 GB |
|---|---|---|---|---|---|
| 4k | 0.01 GB | 93.67 GB | no | no | no |
| 8k | 0.01 GB | 93.79 GB | no | no | no |
| 16k | 0.01 GB | 94.04 GB | no | no | no |
| 32k | 0.01 GB | 94.54 GB | no | no | no |
| 64k | 0.01 GB | 95.54 GB | no | no | no |
| 128k | 0.01 GB | 97.54 GB | no | no | no |
The "fits" columns allow for the roughly 0.8 GB Windows keeps for the desktop.
