Frequently Asked Questions
- How much VRAM does DeepSeek V3.1 need?
DeepSeek V3.1 requires 414.6 GB of VRAM at Q4_K_M, or 491.6 GB at Q5_K_M. Full 164K context adds up to 283.0 GB (697.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 684.5B × 4.8 bits ÷ 8 = 410.7 GB
KV Cache + Overhead ≈ 3.9 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 286.9 GB (at full 164K context)
