gemma-4-E2B-it-NVFP4A16

Model Overview

—Base Model: google/gemma-4-E2B-it
—Quantization: NVFP4A16 (4-bit NV floating point weights, 16-bit activations)
—Quantization Tool: llm-compressor

Description

This model is a weight-only NVFP4A16 quantized version of Google's Gemma 4 E2B instruction-tuned model. Weights are quantized to FP4 with per-group (group size 16) quantization using the NVIDIA FP4 format, while activations remain in FP16.

The following modules are kept in their original precision:

—lm_head
—Vision encoder (vision_tower)
—Audio encoder (audio_tower)
—Vision embedding projection (embed_vision)
—Audio embedding projection (embed_audio)

How It Was Made

python

from transformers import AutoModelForImageTextToText, AutoProcessor
from llmcompressor import oneshot
from llmcompressor.modifiers.quantization import QuantizationModifier

MODEL_ID = "google/gemma-4-E2B-it"
model = AutoModelForImageTextToText.from_pretrained(MODEL_ID, dtype="auto")

recipe = QuantizationModifier(
    targets="Linear",
    scheme="NVFP4A16",
    ignore=[
        "lm_head",
        "re:.*vision_tower.*",
        "re:.*audio_tower.*",
        "re:.*embed_vision.*",
        "re:.*embed_audio.*",
    ],
)

oneshot(model=model, recipe=recipe)
model.save_pretrained("gemma-4-E2B-it-NVFP4A16", save_compressed=True)
