Gemma 4 E4B, self-quantized to GGUF by Atomic Chat. Built straight from Google's original weights with a per-tensor importance matrix. Runs fully offline.

Highlights

• Natively multimodal — handles text, image, and audio input and generates text output.
• 4.5B effective parameters (8B with embeddings) — the "E" stands for "effective", using Per-Layer Embeddings (PLE) for on-device efficiency.
• 128K-token context window built on a hybrid local/global attention mechanism.
• Built-in thinking mode — configurable step-by-step reasoning, triggered with the <|think|> token.
• Native function calling for structured tool use and agentic workflows.
• Multilingual — out-of-the-box support for 35+ languages, pre-trained on 140+ languages.

[!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 E4B chat template is applied. Without it the model can emit malformed turns.

Model Overview

[!NOTE] Gemma 4 E4B is multimodal. This repo ships the mmproj-gemma4-e4b-it-f16.gguf vision projector. With -hf it is pulled automatically; otherwise pass --mmproj. Use llama-mtmd-cli or llama-server to feed images.

Scores are Google's published results for the base google/gemma-4-E4B-it. Quantization preserves the large majority of this; Q4_K_M and up sit within a point or two of full precision.

Choosing a quant

[!TIP] Pick the largest file that fits your (V)RAM with room for context. Q4_K_M or UD-Q4_K_XL is the sweet spot for most setups; Q6_K or Q8_0 for maximum fidelity.

Get started

Run Gemma 4 E4B locally with:

• Atomic Chat: the easiest path. Open the app, search AlexAtomic/gemma4-e4b-it-GGUF, pick a quant, hit Use this model.
• llama.cpp: llama-server -hf AlexAtomic/gemma4-e4b-it-GGUF:Q4_K_M --jinja -c 8192
• Ollama: ollama run hf.co/AlexAtomic/gemma4-e4b-it-GGUF:Q4_K_M
• LM Studio / Jan: search the repo id, download any quant.

Best practices

Google's standardized sampling configuration recommended across all use cases.

Run in llama.cpp

git clone https://github.com/ggerganov/llama.cpp
cmake llama.cpp -B llama.cpp/build -DBUILD_SHARED_LIBS=OFF -DGGML_CUDA=ON
cmake --build llama.cpp/build --config Release -j --target llama-cli llama-server

./llama.cpp/build/bin/llama-server \
    -hf AlexAtomic/gemma4-e4b-it-GGUF:UD-Q4_K_XL \
    --jinja -ngl 99 -c 8192 -fa on

How these were made

1. Download google/gemma-4-E4B-it (original weights).
2. Convert to f16 GGUF with llama.cpp.
3. Build an importance matrix over calibration_datav3 (100 chunks).
4. Quantize the full ladder with --imatrix.
5. UD-Q4_K_XL additionally pins the token-embedding and output tensors to Q8_0.
