Can I Run Cogito v1 on Apple M1 Max?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes, but it's tight — Cogito v1 70B at Q4_K_M needs 45.7 GB at 8K context (42.3 GB weights + 3.4 GB KV cache/overhead), leaving ~2.3 GB of the Apple M1 Max's 48 GB usable memory, at ~5 tok/s (est.), with room for up to 8K context.

Cogito v1 70B on the Apple M1 Max: 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 64 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 M1 Max: 8K 45.7 GB · 32K 53.8 GB ✗ · 128K 86 GB ✗. Past 32K it no longer fits 64 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Cogito v1 on 8 GB of system RAM, CPU only: runs.
