Can I Run Nemotron Cascade 2 on Apple M2 Max?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes, comfortably — Nemotron Cascade 2 70B at Q4_K_M needs 45.4 GB at 8K context (42.3 GB weights + 3.1 GB KV cache/overhead), leaving ~26.6 GB of the Apple M2 Max's 72 GB usable memory, at ~5 tok/s (est.), with room for up to 64K context.

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 96 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 Max: 8K 45.4 GB · 32K 52.6 GB · 125K 80.3 GB ✗. Past 125K it no longer fits 96 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Nemotron Cascade 2 on 24 GB of system RAM, CPU only: runs.
