Gemma 4 31B It Assistant, self-quantized to GGUF by Atomic Chat. Built straight from Google's original weights with a per-tensor importance matrix, so this is not a repack of somebody else's files. Runs fully offline.

Highlights

  • —30.7B parameters: the weights this repo quantizes.
  • —Context length: 256K tokens, as published by Google.
  • —60 layers: Dense decoder, hybrid sliding-window (1024) and global attention.
  • —Modalities: the base model handles Text, Image; this repo ships text-only quants, it carries no vision projector.
  • —Full imatrix ladder: every quant is calibrated with an importance matrix.
  • —Reasoning: All models in the family are designed as highly capable reasoners, with configurable thinking modes.
  • —Diverse & Efficient Architectures: Offers Dense and Mixture-of-Experts (MoE) variants of different sizes for scalable deployment.
[!NOTE] These GGUFs are self-quantized from the original weights, not a repack. The importance matrix keeps low-bit quants closer to the full-precision model.
[!IMPORTANT] Always pass --jinja so the Gemma 4 31B It Assistant chat template is applied. Without it the model can emit malformed turns.

Scores are Google's published results for the base google/gemma-4-31B-it-assistant, not our own measurements. Quantization preserves the large majority of this; Q4_K_M and up stay close to full precision.

Choosing a quant

QuantSizeNotes
Q4_K_S349 MBCompact 4-bit, fast.
`Q4_K_M`353 MBRecommended default. Best balance of size, speed and quality.
Q5_K_M377 MBHigher quality, low loss.
Q8_00.5 GBEffectively lossless, reference quality.
F161.0 GBUnquantized reference, twice the size of Q8_0.
[!TIP] Pick the largest file that fits your (V)RAM with room for context. Q4_K_M is the sweet spot for most setups; Q6_K or Q8_0 for maximum fidelity.

Get started

    --jinja -ngl 99 -c 8192 -fa on

How these were made

  1. 1.Download google/gemma-4-31B-it-assistant (original weights).
  2. 2.Convert to f16 GGUF with llama.cpp.
  3. 3.Build an importance matrix over our calibration corpus.
  4. 4.Quantize the ladder with --imatrix.
