Can I Run DeepSeek V4-Flash on Apple M2 Max?
Written by Jakub Rusinowski · Last updated September 29, 2026
No. DeepSeek V4-Flash needs 172.8 GB at 8K context (171.5 GB weights + 1.3 GB KV cache/overhead) at Q4 (experimental) and the Apple M2 Max has only 72 GB usable. No quantization we publish closes a gap that size.

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.
What to do next
Either step down to a smaller size in this family, or move to a Apple M5 Ultra (512 GB), the card with the least memory we track that holds it.
No compatible GPU? DeepSeek V4-Flash on 128 GB of system RAM, CPU only: runs, but it is tight.
