Only with CPU offload
Qwen3.6 35B-A3B at Q4_K_M needs 20.9 GB but only 10.6 GB is addressable, so about 51% of the layers would stream from system RAM at roughly 60 GB/s. Expect around 14 tokens per second — usable for batch work, painful for chat.

Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. Only 10 of its 40 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
$ llama-server \
-hf Qwen/Qwen3.6-35B-A3B:Q4_K_M \
-c 8192 -ngl 19
The engine underneath most of the others. Every knob is exposed. More on llama.cpp.
01Download is 20.2 GB. Keep it on an SSD — a first load off a spinning disk takes minutes.
02Close anything else holding VRAM. A browser with hardware acceleration can sit on 1–2 GB.
03If it falls back to CPU silently, drop the context first, then step down a quantisation.
