Gemma 4 E2B int8 for gemma4.c

This is the ready-to-run model file for gemma4.c, a small educational implementation of Gemma 4 E2B inference on CPU.

The project's exporter.py converts the original Google Gemma 4 E2B QAT checkpoint into one 4.7 GiB file containing the model configuration, tokenizer, and weights. During export, matrix weights are quantized to int8 with FP16 scales.

Download

hf download QmogAI/gemma4-e2b-int8 gemma4-E2B-int8.bin --local-dir .

Run

git clone https://github.com/ryanssenn/gemma4.c
cd gemma4.c
make
./run -m ./gemma4-E2B-int8.bin -t 1.0 -n 256 "Why is the sky blue?"

Export your own

If you would rather create the file from the original checkpoint:

python3 -m pip install -r requirements.txt
python3 exporter.py /path/to/gemma-4-E2B-it-qat-q4_0-unquantized -o ./gemma4-E2B-int8.bin

The runtime is made for x86-64 CPUs with AVX2 and FMA. AVX-512 VNNI is used when available. It is intended for learning and experimentation.
