Frequently Asked Questions
- How much VRAM does Qwen3.8 Flash Next OQ5e Mtp need?
Qwen3.8 Flash Next OQ5e Mtp requires 108.4 GB of VRAM at Q4_K_M, or 360.4 GB at BF16. Full 262K context adds up to 10.7 GB (119.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 180.0B × 4.8 bits ÷ 8 = 108 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11 GB (at full 262K context)
