Can I Run Aya Expanse 8B on Apple M4?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Yes. Aya Expanse 8B needs 6.7 GB at 8K context (4.8 GB weights + 1.9 GB KV cache/overhead) at Q4_K_M and the Apple M4 has 24 GB usable, leaving about 17.3 GB of headroom, at roughly 12 tok/s (estimated) with room for up to 8K of context.

Aya Expanse 8B on the Apple M4: VRAM by quantization
| Quant | VRAM needed | Fits 32 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 17.9 GB | ✓ Yes | 8K | — |
| Q8_0 | 10.4 GB | ✓ Yes | 8K | — |
| Q6_K | 8.5 GB | ✓ Yes | 8K | — |

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 32 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
