Yes, just — 0.2 GB spare
DeepSeek-R1-Distill-Qwen 14B at Q4_K_M fits your Radeon RX 6700 XT entirely on the GPU at 8K context, at an estimated 28 tokens per second. Past 8K the KV cache pushes it over — quantise the cache to q8_0, or step down a quantisation, to go longer.

| F16 | 27.6 GB | 29.7 GB | — | ~1.8 | Reference | 19.1 GB over |
| Q8_0 | 14.6 GB | 16.7 GB | — | ~4.9 | −0.1% ppl | 6.1 GB over |

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-14B:Q4_K_M \
-c 8192 -ngl 99
The engine underneath most of the others. Every knob is exposed. More on llama.cpp.
01Download is 8.3 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 0.2 GB is spare, so a long system prompt can still push it over. Its real ceiling here is 8K context.
