Short answerA M3 Ultra 256GB is the smallest Apple Silicon machine that loads DeepSeek V4 Flash Vision Exp at Q4_K_M with an 8K context, at roughly 4 tokens/sec. Mac Studio (M3 Ultra) is the cheapest way to get that configuration.

Download size by quantisation
Weight memory scales linearly with bits per parameter. Everything below assumes an 8K context on top.
| Quantisation | Weights | Total @ 8K | Notes |
|---|---|---|---|
| FP16 | 567.5 GiB | 597.3 GiB | Full precision. Reference quality, twice the memory of Q8. |
| Q8_0 | 301.5 GiB | 318.0 GiB | Indistinguishable from FP16 in practice, at half the size. |
| Q6_K | 234.1 GiB | 247.3 GiB | Near-lossless. A good stop when you have memory to spare. |
| Q5_K_M | 202.2 GiB | 213.7 GiB | Slightly better than Q4_K_M, noticeably bigger. |
| Q4_K_M | 173.8 GiB | 183.9 GiB | The default. Best quality-per-gigabyte for most people. |
| Q3_K_M | 138.3 GiB | 146.7 GiB | Visible quality loss. Use to squeeze one size class up. |
| Q2_K | 106.4 GiB | 113.2 GiB | Last resort. Often worse than a smaller model at Q4. |
Partly estimatedThis model was added automatically from its published config. Its parameter count and KV cache size are exact, but the config did not expose the expert shapes needed to work out how many parameters are read per token — so the speed estimate assumes every parameter is read, and the real figure is likely faster. Memory numbers are unaffected.
