Only with CPU offload
DeepSeek-R1-Distill-Qwen 32B at Q4_K_M needs 21.0 GB but only 10.6 GB is addressable, so about 57% of the layers would stream from system RAM at roughly 60 GB/s. Expect around 3.1 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.
How to run it
$ llama-server \
-hf deepseek-ai/DeepSeek-R1-Distill-Qwen-32B:Q4_K_M \
-c 8192 -ngl 27
The engine underneath most of the others. Every knob is exposed. More on llama.cpp.
01Download is 18.4 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.
