Can I Run IBM Granite 4.1 on Apple M1 Max?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 29 września 2026
Yes, comfortably — Granite 4.1 30B at FP8 (Q4 est. ~12-15GB, unconfirmed) needs 33.5 GB at 8K context (30.9 GB weights + 2.6 GB KV cache/overhead), leaving ~14.5 GB of the Apple M1 Max's 48 GB usable memory, at ~7 tok/s (est.).

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. 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 FP8 (Q4 est. ~12-15GB, unconfirmed) on the Apple M1 Max: 8K 33.5 GB · 32K 38.9 GB · 128K 60.2 GB ✗. Past 128K 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? Granite 4.1 30B on 32 GB of system RAM, CPU only: runs comfortably.
