Frequently Asked Questions
- How much VRAM does MLX Qwen3.5 9B Claude 4.6 Opus Reasoning Distilled 4bit need?
MLX Qwen3.5 9B Claude 4.6 Opus Reasoning Distilled 4bit requires 1.4 GB of VRAM at Q4_K_M, or 2.0 GB at Q8_0. Full 262K context adds up to 34.1 GB (35.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1.4B × 4.8 bits ÷ 8 = 0.8 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 34.7 GB (at full 262K context)
