Frequently Asked Questions
- How much VRAM does Qwen3.5 27B Claude 4.6 Opus Reasoning Distilled Heretic V1 need?
Qwen3.5 27B Claude 4.6 Opus Reasoning Distilled Heretic V1 requires 17.2 GB of VRAM at Q4_K_M, or 55.5 GB at BF16. Full 262K context adds up to 56.8 GB (74.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 27.4B × 4.8 bits ÷ 8 = 16.4 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 57.6 GB (at full 262K context)
