Qwen3.8-Max — VRAM Requirements
Written by Jakub Rusinowski · Last updated September 6, 2026
How much GPU VRAM you need to run Qwen3.8 Qwen3.8-Max by Alibaba Cloud locally, a 2400B-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.
Qwen3.8-Max needs about 1450 GB VRAM at Q4_K_M.
VRAM by Quantization
