🍦 gemma-4-E4B-it — Imatrix GGUF

> Verified quants only. Sub-4-bit variants are excluded from this release because they produce degenerate output on this model size — no point shipping broken files.

GGUF imatrix builds of google/gemma-4-E4B-it.

Built with llama.cpp and importance-matrix calibration on a public multilingual + code + math corpus. Every quant is loaded, prompted, and visually checked before publication.

👋 From the author

Hi local LLM enthusiasts! You may have noticed a few quants from me over the past months — those were one-off experiments. This release is the first one from a fully automated pipeline.

Please try them out, share feedback, and let me know which quants you find useful or which ones you wish I had made. For now, anything below 4-bit produces degraded output on this architecture, so I am holding off on those until they actually work well. More quants and more models coming.

🎯 Pick a quant

| Quant | Size | What it's for |

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

| Q8_0 | 7.5G | Almost the original. Pick this if RAM isn't a concern. |

| Q6_K_L | 6.6G | Near-lossless with Q8_0 embeddings. Best of the K-quants. |

| Q6_K | 5.8G | Near-lossless. Excellent fidelity at smaller size than Q8_0. |

| Q5_K_L | 6.2G | Q5_K_M with Q8_0 embeddings. High quality, small overhead. |

| Q5_K_M | 5.4G | Sweet spot between Q4 and Q6. Solid all-rounder. |

| Q5_K_S | 5.3G | Slightly smaller than Q5_K_M, virtually identical output. |

| Q4_K_L | 5.8G | Q4_K_M with Q8_0 embeddings. The smart 4-bit choice. |

| Q4_K_M | 5.0G | The default. Most-downloaded quant for a reason. |

| Q4_K_S | 4.9G | A bit smaller than Q4_K_M, a tiny step down. |

| IQ4_NL | 4.9G | ARM-optimized 4-bit. For Raspberry Pi & friends. |

| IQ4_XS | 4.8G | Tightest 4-bit format. Quality close to Q4_K_S, smaller. |

*_L variants override the output tensor and embeddings to Q8_0 — small disk cost, better output stability.

Tl;dr:

• 🟢 Q4_K_M — start here unless you have a reason not to
• 🟡 Q5_K_M — small quality bump if you have RAM to spare
• 🔵 Q8_0 — pick this if you're not RAM-constrained and want max quality
• 🟠 IQ4_XS — when 4-bit is too big
• 🟣 IQ4_NL — running on ARM (Pi, phones)

🔬 Calibration

Imatrix generated from reapmix — community calibration mix (~400K tokens, multilingual + code + math). Same class of public calibration data used by other community publishers; this release makes no unique calibration claim.

The output tensor and embeddings carry disproportionate weight in quantized output. The *_L variants keep these at Q8_0 — small disk cost for noticeably better stability at low bit-rates.
