DeepSeek-R1 distills, the reasoning sweet spot
The full DeepSeek-R1 671B is impractical on consumer hardware, but the official distilled variants, derived by training Qwen 2.5 and Llama 3 backbones on R1's chain-of-thought traces , punch dramatically above their weight on math, code, and multi-step reasoning evals. R1-Distill-Qwen-32B at Q5_K_M is, in our testing, the single best reasoning model that fits in a 24 GB consumer card.
Watch the <think> tags. R1 distills generate hidden chain-of-thought before producing the final answer; the resulting context is often 2–4× the user-visible response. KV cache balloons accordingly. If you regularly push the context window past 16k tokens, plan for ~25% additional VRAM overhead beyond the table above.
Recommended
R1-Distill-Qwen-32B Q5_K_M on RTX 5090 32 GB. ~48 tok/s, 16k context fits.
Avoid
R1 distills at Q2 / Q3, reasoning collapses fast under aggressive quantization.
