No — not on this device
Qwen3.8 2.4T-A95B at Q4_K_M needs 1376.7 GB against 48.0 GB usable, and the shortfall of 1328.7 GB is more than 256 GB of system RAM can cover at a tolerable speed. A smaller sibling or a lower quantisation is the honest answer here.
The first open Qwen-Max-class flagship. Listed as the honest ceiling: nothing short of a rack runs it.

Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. Only 23 of its 92 blocks keep a per-token KV cache; the rest are linear-attention, Mamba or convolution blocks with a fixed-size state.
