Can I Run DeepSeek V4 on Apple M2 Max?
Written by Jakub Rusinowski · Last updated September 29, 2026
No — DeepSeek V4-Flash at Q4 (experimental) needs 172.8 GB at 8K context (171.5 GB weights + 1.3 GB KV cache/overhead), and the Apple M2 Max's 72 GB usable memory leaves it ~100.8 GB short. The cheapest card that runs it is the Apple M5 Ultra (512 GB).

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 (experimental) on the Apple M2 Max: 8K 172.8 GB ✗ · 32K 174.6 GB ✗ · 128K 181.5 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-Flash on 128 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every DeepSeek V4 variant requires more VRAM than the Apple M2 Max provides (96 GB).
Nearest GPU That Fits
Apple M5 Ultra (512 GB VRAM).
DeepSeek V4 needs ~173 GB but this GPU has 96 GB. Rent a 8× H100 (640 GB)-class GPU by the hour instead of buying one:
