Frequently Asked Questions
- How much VRAM does MLX Qwen3.5 9B Claude 4.6 Opus Reasoning Distilled 6bit need?
MLX Qwen3.5 9B Claude 4.6 Opus Reasoning Distilled 6bit requires 5.9 GB of VRAM at Q4_K_M, or 9.5 GB at Q8_0. Full 262K context adds up to 34.1 GB (40.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 9.0B × 4.8 bits ÷ 8 = 5.4 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 34.6 GB (at full 262K context)
