Frequently Asked Questions
- How much VRAM does Josiefied Qwen3 8B Abliterated V1 need?
Josiefied Qwen3 8B Abliterated V1 requires 5.5 GB of VRAM at Q4_K_M, or 8.8 GB at Q8_0. Full 41K context adds up to 5.7 GB (11.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.2B × 4.8 bits ÷ 8 = 4.9 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 6.4 GB (at full 41K context)
