Frequently Asked Questions
- How much VRAM does Vikhr Nemo 12B Instruct R 21 09 24 need?
Vikhr Nemo 12B Instruct R 21 09 24 requires 8.1 GB of VRAM at Q4_K_M, or 25.2 GB at BF16. Full 1024K context adds up to 209.3 GB (217.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 12.2B × 4.8 bits ÷ 8 = 7.3 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 210.1 GB (at full 1024K context)
