Frequently Asked Questions
- How much VRAM does Datarus R1 14B Preview need?
Datarus R1 14B Preview requires 8.1 GB of VRAM at Q4_0, or 15.5 GB at Q8_0. Full 131K context adds up to 25.4 GB (33.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 14.8B × 4 bits ÷ 8 = 7.4 GB
KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 26.1 GB (at full 131K context)
VRAM usage by quantization
