Can I Run Mistral Small 3.1 on Apple M2?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes, but it's tight — Mistral Small 3.1 24B at Q4_K_M needs 16.4 GB at 8K context (14.2 GB weights + 2.2 GB KV cache/overhead), leaving ~1.6 GB of the Apple M2's 18 GB usable memory, at ~4 tok/s (est.), with room for up to 16K context.

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 24 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Apple M2: 8K 16.4 GB · 32K 20.4 GB ✗ · 125K 36 GB ✗. Past 32K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Mistral Small 3.1 24B on 16 GB of system RAM, CPU only: runs, but it is tight.
