Gemma 3 4b Novision

🚀 Gemma-3-4b Text-Only

This model is a text-only version converted from the multimodal Gemma-3-4b-it, offering pure text generation capabilities.

🚀 Quick Start

This model is a text-only version of google/gemma-3-4b-it, converted from the multimodal Gemma3ForConditionalGeneration architecture to the text-only Gemma3ForCausalLM architecture.

✨ Features

• Original Model: The original Gemma-3-4b-it is a multimodal model released by Google that can process both text and images.
• This Version: This version has been modified to use the same architecture as the text-only 1b model, with the vision components removed.
• Parameters: 4 billion parameters.
• Conversion Process: Vision-related components were stripped while maintaining the text generation capabilities.

📦 Installation

No specific installation steps are provided in the original document.

💻 Usage Examples

Basic Usage

from transformers import AutoTokenizer, BitsAndBytesConfig, Gemma3ForCausalLM
import torch

model_id = "gghfez/gemma-3-4b-novision"

quantization_config = BitsAndBytesConfig(load_in_8bit=True)

model = Gemma3ForCausalLM.from_pretrained(
    model_id, quantization_config=quantization_config
).eval()

tokenizer = AutoTokenizer.from_pretrained(model_id)

messages = [
    [
        {
            "role": "system",
            "content": [{"type": "text", "text": "You are a helpful assistant."},]
        },
        {
            "role": "user",
            "content": [{"type": "text", "text": "Write a poem on Hugging Face, the company"},]
        },
    ],
]
inputs = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device).to(torch.bfloat16)


with torch.inference_mode():
    outputs = model.generate(**inputs, max_new_tokens=64)

outputs = tokenizer.batch_decode(outputs)
