Qwen 3 VL (8B) has 8 billion parameters. At standard 4-bit quantization with 8K context, it needs roughly 7.4 GB of VRAM — weights plus cache and runtime overhead.
VRAM by quantization
| Precision | Weights | Cache/Buffer | Total VRAM |
|---|---|---|---|
| 2-bit (IQ2_XXS) | 2.6 GB | 1.0 GB | 5.5 GB |
| 4-bit (Q4_K_M) | 4.4 GB | 1.0 GB | 7.4 GB |
| 8-bit (Q8_0) | 8.4 GB | 1.0 GB | 11.4 GB |
| 16-bit (FP16) | 16.0 GB | 1.0 GB | 19.0 GB |
