Can I Run Cogito v1 70B on Apple M3 Pro?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 29 września 2026
Not at Q4_K_M — that needs 45.7 GB at 8K context and the Apple M3 Pro has 27 GB usable. Drop to Q2_K and it fits in 26.5 GB, with up to 8K of context.

Cogito v1 70B on the Apple M3 Pro: VRAM by quantization

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 36 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 M3 Pro: 8K 45.7 GB ✗ · 32K 53.8 GB ✗ · 128K 86 GB ✗. Past 8K it no longer fits 36 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q2_K. That is the cheapest fix — it costs some quality but no money.
