No — not on this device

Qwen3.8 2.4T-A95B at Q4_K_M needs 1376.7 GB against 25.6 GB usable, and the shortfall of 1351.1 GB is more than 32 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.

How to run it

terminal
$ llama-server \
    -hf Qwen/Qwen3.8-2.4T-A95B:Q4_K_M \
    -c 8192 -ngl 1

The engine underneath most of the others. Every knob is exposed. More on llama.cpp.

01Download is 1375.4 GB. Keep it on an SSD — a first load off a spinning disk takes minutes.
02With no GPU, thread count matters more than clock. Start at one thread per physical core.
03If it falls back to CPU silently, drop the context first, then step down a quantisation.
