Gemma 4 E2B 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
- 2.3B effective (5.1B with embeddings) parameters: the weights this repo quantizes.
- Context length: 128K tokens, as published by Google.
- 35 layers: Dense decoder, hybrid sliding-window (512) and global attention.
- Modalities: the base model handles Text, Image, Audio; 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
--jinjaso the Gemma 4 E2B It Assistant chat template is applied. Without it the model can emit malformed turns.
Model Overview
| Property | Value |
|---|---|
| Base model | google/gemma-4-E2B-it-assistant |
| Parameters | 2.3B effective (5.1B with embeddings) |
| Layers | 35 |
| Sliding window | 512 tokens |
| Context length | 128K tokens |
| Vocabulary | 262K |
| Modalities | Text, Image, Audio in the base model; text only in this repo, it ships no vision projector |
| Architecture | Dense decoder, hybrid sliding-window (512) and global attention, 4 attention heads over 1 KV head, Gemma4AssistantForCausalLM |
| This repo | GGUF quants (imatrix). Quants: Q4_K_S, Q4_K_M, Q5_K_M, Q8_0, F16 |
Benchmarks
| Benchmark | Score |
|---|---|
| MMLU Pro | 60.0% |
| AIME 2026 no tools | 37.5% |
| LiveCodeBench v6 | 44.0% |
| Codeforces ELO | 633 |
| GPQA Diamond | 43.4% |
| Tau2 (average over 3) | 24.5% |
| BigBench Extra Hard | 21.9% |
| MMMLU | 67.4% |
| MMMU Pro | 44.2% |
| OmniDocBench 1.5 (average edit distance, lower is better) | 0.290 |
| MATH-Vision | 52.4% |
| MedXPertQA MM | 23.5% |
| CoVoST | 33.47 |
| FLEURS (lower is better) | 0.09 |
| MRCR v2 8 needle 128k (average) | 19.1% |
Scores are Google's published results for the base google/gemma-4-E2B-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
| Quant | Size | Notes |
|---|---|---|
Q4_K_S | 78 MB | Compact 4-bit, fast. |
Q4_K_M | 78 MB | Recommended default. Best balance of size, speed and quality. |
Q5_K_M | 79 MB | Higher quality, low loss. |
Q8_0 | 99 MB | Effectively lossless, reference quality. |
F16 | 172 MB | Unquantized reference, twice the size of Q8_0. |
[!TIP] Pick the largest file that fits your (V)RAM with room for context.
Q4_K_Mis the sweet spot for most setups;Q6_KorQ8_0for maximum fidelity.
Get started
Run Gemma 4 E2B It Assistant locally with:
- Atomic Chat: the easiest path. Open the app, search
AtomicChat/gemma-4-E2B-it-assistant-GGUF, pick a quant, hit Use this model. - llama.cpp:
