Short answerA M2 24GB is the smallest Apple Silicon machine that loads Mistral Small 3 24B at Q4_K_M with an 8K context, at roughly 6 tokens/sec. MacBook Air 15" (M2) 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 | 44.0 GiB | 48.2 GiB | Full precision. Reference quality, twice the memory of Q8. |
| Q8_0 | 23.4 GiB | 26.6 GiB | Indistinguishable from FP16 in practice, at half the size. |
| Q6_K | 18.1 GiB | 21.1 GiB | Near-lossless. A good stop when you have memory to spare. |
| Q5_K_M | 15.7 GiB | 18.5 GiB | Slightly better than Q4_K_M, noticeably bigger. |
| Q4_K_M | 13.5 GiB | 16.2 GiB | The default. Best quality-per-gigabyte for most people. |
| Q3_K_M | 10.7 GiB | 13.3 GiB | Visible quality loss. Use to squeeze one size class up. |
| Q2_K | 8.2 GiB | 10.7 GiB | Last resort. Often worse than a smaller model at Q4. |
