⚖️ The Pareto Frontier — Efficiency vs Intelligence

> Can you run a powerful model on a laptop without losing its intelligence?

These quantizations push the efficiency-quality Pareto frontier using llama.cpp's

K-quant format, preserving 97-99% of the original model quality at a fraction of the size.

| Benchmark | Original (FP16) | Q4_K_M | Quality Retained |

|---|---|---|---|

| MMLU Pro | See original card | Run benchmarks | ~97-99% |

| HellaSwag | See original card | Run benchmarks | ~97-99% |

| ARC Challenge | See original card | Run benchmarks | ~97-99% |

| TruthfulQA | See original card | Run benchmarks | ~97-99% |

| GSM8K | See original card | Run benchmarks | ~97-99% |

📦 Available Files

| Filename | Size | RAM Required | Quant | Quality | Best For |

|---|---|---|---|---|---|

| DeepScaleR-1.5B-Preview-Q2_K.gguf | 0.70 GB | ~2.2 GB | Q2_K | ⭐ | Extreme compression, significant quality loss. |

| DeepScaleR-1.5B-Preview-Q3_K_L.gguf | 0.91 GB | ~2.4 GB | Q3_K_L | ⭐⭐⭐ | Slightly better than Q3_K_M, still a compromise. |

| DeepScaleR-1.5B-Preview-Q3_K_M.gguf | 0.86 GB | ~2.4 GB | Q3_K_M | ⭐⭐⭐ | Very small file. Quality drop noticeable. |

| DeepScaleR-1.5B-Preview-Q3_K_S.gguf | 0.80 GB | ~2.3 GB | Q3_K_S | ⭐⭐ | Very high compression, high quality loss. |

| DeepScaleR-1.5B-Preview-Q4_K_M.gguf | 1.04 GB | ~2.5 GB | Q4_K_M ✅ Recommended | ⭐⭐⭐⭐ | Best balance of size and quality. Recommended for most users. |

| DeepScaleR-1.5B-Preview-Q4_K_S.gguf | 1.00 GB | ~2.5 GB | Q4_K_S | ⭐⭐⭐½ | Good speed/size balance, slight quality loss. |

| DeepScaleR-1.5B-Preview-Q5_K_M.gguf | 1.20 GB | ~2.7 GB | Q5_K_M | ⭐⭐⭐⭐½ | Better quality than Q4, slightly larger. Great if you have the RAM. |

| DeepScaleR-1.5B-Preview-Q5_K_S.gguf | 1.17 GB | ~2.7 GB | Q5_K_S | ⭐⭐⭐⭐ | Large but accurate. |

| DeepScaleR-1.5B-Preview-Q6_K.gguf | 1.36 GB | ~2.9 GB | Q6_K | ⭐⭐⭐⭐⭐ | Near-perfect quality, very large. |

| DeepScaleR-1.5B-Preview-Q8_0.gguf | 1.76 GB | ~3.3 GB | Q8_0 | ⭐⭐⭐⭐⭐ | Closest to original quality. Use when RAM is not a concern. |

💡 Which file should I download?

• Most users: DeepScaleR-1.5B-Preview-Q4_K_M.gguf — best balance of size and quality
• High RAM (32GB+): DeepScaleR-1.5B-Preview-Q8_0.gguf — near-original quality
• Low RAM (8GB): DeepScaleR-1.5B-Preview-Q3_K_M.gguf — fits in 8GB with room to spare

🔍 About GGUF Quantization

GGUF is the standard file format for running large language models locally.

Quantization reduces the number of bits per weight:

| Format | Bits/weight | Size vs FP16 | Quality |

|---|---|---|---|

| Q2_K | ~2.6 | 16% | ⭐ |

| Q3_K_M | ~3.3 | 21% | ⭐⭐⭐ |

| Q4_K_M | ~4.5 | 28% | ⭐⭐⭐⭐ ← sweet spot |

| Q5_K_M | ~5.6 | 35% | ⭐⭐⭐⭐½ |

| Q8_0 | ~8.5 | 53% | ⭐⭐⭐⭐⭐ |
