Written by Jakub Rusinowski · Last updated April 28, 2025
How much GPU VRAM you need to run Qwen 3 Qwen 3 30B-A3B (MoE) by Alibaba Cloud locally, a 30.5B-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.
Qwen 3 30B-A3B (MoE) needs about 20 GB VRAM at Q4_K_M.
VRAM by Quantization
