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.
Model Overview
Benchmarks
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
[!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.
