Only with CPU offload

DeepSeek-R1-Distill-Llama 70B at Q4_K_M needs 42.8 GB but only 8.8 GB is addressable, so about 86% of the layers would stream from system RAM at roughly 60 GB/s. Expect around 1.1 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

terminal
$ llama-server \
    -hf deepseek-ai/DeepSeek-R1-Distill-Llama-70B:Q4_K_M \
    -c 8192 -ngl 11

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

01Download is 39.7 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.
