Qwen3-Coder 8B — VRAM Requirements
Written by Jakub Rusinowski · Last updated February 5, 2026
How much GPU VRAM you need to run Qwen3-Coder Qwen3-Coder 8B by Alibaba Cloud locally, a 8B-parameter model. Figures are quantized weights + KV cache + framework overhead, computed from the model's parameter count and published architecture — not a throughput model. See /en/methodology.
Qwen3-Coder 8B needs about 6 GB VRAM at Q4_K_M.
VRAM by Quantization
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 2.6 GB | 3.4 GB |
| Q3_K_M | 3.41 | 3.4 GB | 4.2 GB |
| Q4_K_M | 4.83 | 4.8 GB | 5.6 GB |
| Q5_K_M | 5.67 | 5.7 GB | 6.5 GB |
| Q6_K | 6.56 | 6.6 GB | 7.4 GB |
| Q8_0 | 8.50 | 8.5 GB | 9.3 GB |
| F16 | 16.00 | 16.0 GB | 16.8 GB |
