Frequently Asked Questions

How much VRAM does Xing4.0 29B A4B need?

Xing4.0 29B A4B requires 20.2 GB of VRAM at Q4_K_M, or 63.9 GB at BF16. Full 262K context adds up to 149.2 GB (169.3 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 31.2B × 4.8 bits ÷ 8 = 18.7 GB

KV Cache + Overhead ≈ 1.5 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead ≈ 150.7 GB (at full 262K context)
