Can I Run DeepSeek V4.1 on Apple M2 Max?
Written by Jakub Rusinowski · Last updated October 13, 2026
No — DeepSeek V4.1 Flash at Q4_K_M needs 462.2 GB at 8K context (460.8 GB weights + 1.4 GB KV cache/overhead), and the Apple M2 Max's 72 GB usable memory leaves it ~390.2 GB short.

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 462.2 GB ✗ · 32K 463.9 GB ✗ · 128K 470.8 GB ✗. Past 8K 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? DeepSeek V4.1 Flash on 256 GB of system RAM, CPU only: still does not fit.
Why It Does Not Fit
Every DeepSeek V4.1 variant requires more VRAM than the Apple M2 Max provides (96 GB).
DeepSeek V4.1 needs ~462 GB but this GPU has 96 GB. Rent a 8× H100 (640 GB)-class GPU by the hour instead of buying one:
