Frequently Asked Questions
- How much VRAM does Qwen3.8 27B Abliterated MTPLX Optimized Speed need?
Qwen3.8 27B Abliterated MTPLX Optimized Speed requires 54.5 GB of VRAM at BF16. Full 262K context adds up to 56.8 GB (111.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 26.9B × 16 bits ÷ 8 = 53.8 GB
KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 57.6 GB (at full 262K context)
