Frequently Asked Questions
- How much VRAM does DeepSeek Prover v2 671B need?
DeepSeek Prover v2 671B requires 1372.9 GB of VRAM at BF16. Full 164K context adds up to 283.0 GB (1655.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 684.5B × 16 bits ÷ 8 = 1369.1 GB
KV Cache + Overhead ≈ 3.8 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 286.8 GB (at full 164K context)
