Qwen 3 VL (32B) has 32 billion parameters. At standard 4-bit quantization with 8K context, it needs roughly 23.4 GB of VRAM — weights plus cache and runtime overhead.
VRAM by quantization
| Precision | Weights | Cache/Buffer | Total VRAM |
|---|---|---|---|
| 2-bit (IQ2_XXS) | 10.2 GB | 3.8 GB | 16.1 GB |
| 4-bit (Q4_K_M) | 17.6 GB | 3.8 GB | 23.4 GB |
| 8-bit (Q8_0) | 33.6 GB | 3.8 GB | 39.4 GB |
| 16-bit (FP16) | 64.0 GB | 3.8 GB | 69.8 GB |
