| File | Quant | Size | Notes |

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

| nexus-coder-f16.gguf | F16 | 3.09 GB | Full precision (unquantized). Reference / conversion. |

| nexus-coder-q8_0.gguf | Q8_0 | 1.65 GB | Extremely high quality — usually overkill. |

| nexus-coder-q6_k.gguf | Q6_K | 1.27 GB | Very high quality, near-perfect. Recommended if you have the RAM. |

| nexus-coder-q5_k_m.gguf | Q5_K_M | 1.13 GB | High quality. Recommended. |

| nexus-coder-q4_k_m.gguf | Q4_K_M | 0.99 GB | ⭐ Best size/quality balance — default pick for most users. |

| nexus-coder-iq4_xs.gguf | IQ4_XS | 0.90 GB | imatrix — great quality, smaller than Q4_K_S. Recommended for low RAM. |

| nexus-coder-q4_0.gguf | Q4_0 | 0.94 GB | Legacy format — prefer Q4_K_M. |

| nexus-coder-q3_k_m.gguf | Q3_K_M | 0.82 GB | Lower quality; usable when RAM is tight. |

| nexus-coder-iq3_xxs.gguf | IQ3_XXS | 0.44 GB | imatrix very low quality. |

| nexus-coder-q2_k.gguf | Q2_K | 0.68 GB | Very low quality — surprisingly usable. |

| nexus-coder-iq2_xxs.gguf | IQ2_XXS | 0.51 GB | Tiny imatrix — last resort. |

Not sure? Take Q4_K_M. Low RAM → IQ4_XS. Max quality → Q6_K.
