Model Card for RoGemma3-4B-Instruct

Name: RoGemma3-4B-Instruct
Availability: InStock

RoGemma3-4B-Instruct is a Romanian-adapted vision-language model built on top of google/gemma-3-4b-it. It was produced by continued supervised instruction tuning of the base Gemma 3 checkpoint on a Romanian multimodal SFT mixture covering general instruction following (LLaVA mix), captioning (Pixmo-Cap, Flickr30k-Cap), visual question answering (Pixmo-AA, Pixmo-Cap-QA, Flickr30k-QA), document and chart understanding (CoSyn, FinePDFs), and visual grounding (Pixmo-Points, Pixmo-Count). The model is intended for research on Romanian VLM capabilities.

Intended Use

Intended Use Cases

RoGemma3-4B-Instruct is intended for research use on Romanian vision-language tasks — captioning, visual question answering, cultural understanding, OCR / document understanding, and visual grounding — and as a starting point for further Romanian VLM adaptation.

Out-of-Scope Use

Use in any manner that violates applicable laws or regulations (including trade-compliance laws), the project's license, or use in languages other than Romanian.

How to Get Started with the Model

python

import torch
from PIL import Image
from transformers import AutoProcessor, Gemma3ForConditionalGeneration

model = Gemma3ForConditionalGeneration.from_pretrained(
    "OpenLLM-Ro/RoGemma3-4B-Instruct",
    torch_dtype=torch.bfloat16,
    device_map="auto",
).eval()
processor = AutoProcessor.from_pretrained("OpenLLM-Ro/RoGemma3-4B-Instruct")

image = Image.open("example.jpg").convert("RGB")
question = "Descrie imaginea în detaliu."

messages = [
    {"role": "user", "content": [
        {"type": "image", "image": image},
        {"type": "text", "text": question},
    ]},
]
inputs = processor.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device, dtype=torch.bfloat16)

with torch.inference_mode():
    outputs = model.generate(**inputs, max_new_tokens=256, do_sample=False)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))
