Frequently Asked Questions
- How much VRAM does Qwen3.5 2B Claude 4.6 Opus Reasoning Distilled need?
Qwen3.5 2B Claude 4.6 Opus Reasoning Distilled requires 1.8 GB of VRAM at Q4_K_M, or 2.7 GB at Q8_0. Full 262K context adds up to 12.8 GB (14.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 2.3B × 4.8 bits ÷ 8 = 1.4 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 13.2 GB (at full 262K context)
VRAM usage by quantization
