Yes, just — 3.6 GB spare
DeepSeek-R1-Distill-Llama 70B at Q4_K_M fits your RTX A6000 entirely on the GPU at 8K context, at an estimated 12 tokens per second. Past 19K the KV cache pushes it over — quantise the cache to q8_0, or step down a quantisation, to go longer.

Quantisation ladder
| Quant | Weights | Total @ 8K | Max context | Tok/s | Quality | Fit |
|---|---|---|---|---|---|---|
| Q8_0 | 69.9 GB | 73.0 GB | — | ~1.2 | −0.1% ppl | 26.6 GB over |
| Q6_K | 53.9 GB | 57.0 GB | — | ~2.6 | −0.4% ppl | 10.6 GB over |
| Q5_K_M | 46.6 GB | 49.7 GB | — | ~5.4 | −0.8% ppl | 3.3 GB over |
| Q4_K_M | 39.7 GB | 42.8 GB | 19K | 12 | −1.9% ppl | Recommended |

| Q2_K | 27.5 GB | 30.6 GB | 58K | 17 | −15% ppl | Long context |
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 \

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.
03Only 3.6 GB is spare, so a long system prompt can still push it over. Its real ceiling here is 19K context.
