Can I Run DeepSeek V4.1 on NVIDIA A100 80GB (PCIe)?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 13 października 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 NVIDIA A100 80GB (PCIe)'s 80 GB leaves it ~382.2 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 80 GB. 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 NVIDIA A100 80GB (PCIe): 8K 462.2 GB ✗ · 32K 463.9 GB ✗ · 128K 470.8 GB ✗. Past 8K it no longer fits 80 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 NVIDIA A100 80GB (PCIe) provides (80 GB).
DeepSeek V4.1 needs ~462 GB but this GPU has 80 GB. Rent a 8× H100 (640 GB)-class GPU by the hour instead of buying one:
