Frequently Asked Questions
- How much VRAM does Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 need?
Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 requires 1.3 GB of VRAM at Q4_K_M, or 3.5 GB at BF16. Full 41K context adds up to 2.2 GB (3.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1.5B × 4.8 bits ÷ 8 = 0.9 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 2.7 GB (at full 41K context)
