Introduction

VARCO-VISION-2.0 is a multimodal AI model capable of understanding both images and text to answer user queries. It supports multi-image inputs, enabling effective processing of complex content such as documents, tables, and charts. The model demonstrates strong comprehension in both Korean and English, with significantly improved text generation capabilities and a deeper understanding of Korean cultural context. Compared to its predecessor, performance has been notably enhanced across various benchmarks, and its usability in real-world scenarios—such as everyday Q&A and information summarization—has also improved.

In addition to the 14B full-scale model, a lightweight 1.7B version is available for on-device use, making it accessible on personal devices such as smartphones and PCs. VARCO-VISION-2.0 is a powerful open-source AI model built for Korean users and is freely available for a wide range of applications.

Key Features

• —Multi-image Understanding: Newly added support for multi-image inputs enables the model to analyze multiple images simultaneously and make more holistic and context-aware decisions.
• —Korean Language Specialization: The model is further specialized for Korean, with a deeper understanding of Korean language, context, and culture. Korean text generation has been significantly improved, resulting in more natural, fluent, and accurate responses.
• —OCR with Text Localization: Unlike typical models that only recognize and generate text from images, VARCO-VISION-2.0 can also identify the position of the text and provide bounding boxes around it. This makes it especially useful for document understanding, signage interpretation, and structured visual data.
• —Enhanced Safety: Improved robustness and filtering to ensure safer handling of harmful or sexually explicit content.

VARCO-VISION-2.0 Family

Model Architecture

VARCO-VISION-2.0 follows the architecture of LLaVA-OneVision.

Evaluation

We adopted benchmark scores directly from OpenVLM Leaderboard where available, and conducted our own evaluations for benchmarks not included in OpenVLM Leaderboard, comparing results against various open-source models to provide a fair and comprehensive evaluation. Please note that for certain benchmarks involving LLM-based evaluation (e.g., LLaVABench), results may not be exactly reproducible due to variations in the underlying LLM behavior.

English Benchmark

Korean Benchmark

Korean Cultural Benchmark

Text-only Benchmark

Note: Some models show unusually low performance on the MMLU benchmark. This is primarily due to their failure to correctly follow the expected output format when only few-shot exemplars are provided in the prompts. Please take this into consideration when interpreting the results.

OCR Benchmark

Usage

To use this model, we recommend installing transformers version 4.53.1 or higher. While it may work with earlier versions, using 4.53.1 or above is strongly recommended, especially to ensure optimal performance for the multi-image feature.

The basic usage is identical to LLaVA-OneVision:

import torch
from transformers import AutoProcessor, LlavaOnevisionForConditionalGeneration

model_name = "NCSOFT/VARCO-VISION-2.0-14B"
model = LlavaOnevisionForConditionalGeneration.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    attn_implementation="sdpa",
    device_map="auto",
)
processor = AutoProcessor.from_pretrained(model_name)

conversation = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/NCSOFT/VARCO-VISION-2.0-14B/resolve/main/demo.jpg"},
            {"type": "text", "text": "각 박스마다 한 줄씩 색상과 글자를 정확하게 출력해주세요."},
        ],
    },
]

inputs = processor.apply_chat_template(
    conversation,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt"
).to(model.device, torch.float16)

generate_ids = model.generate(**inputs, max_new_tokens=1024)
generate_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generate_ids)
]
output = processor.decode(generate_ids_trimmed[0], skip_special_tokens=True)
print(output)

    {

        "content": [

            {"type": "text", "text": "이미지 간의 유사점을 파악하세요."},
        ],
    },
]

inputs = processor.apply_chat_template(
    conversation,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt"
).to(model.device, torch.float16)

generate_ids = model.generate(**inputs, max_new_tokens=1024)
generate_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generate_ids)
]
output = processor.decode(generate_ids_trimmed[0], skip_special_tokens=True)
print(output)

<details> <summary>Batch inference</summary>

All inputs in a batch must have the same modality structure—for example, text-only with text-only, single-image with single-image, and multi-image inputs with the same number of images—to ensure correct batch inference.

conversation_1 = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "file:///path/to/image1.jpg"},
            {"type": "text", "text": "이미지를 설명해주세요."},
        ],
    },
]

conversation_2 = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "file:///path/to/image2.jpg"},
            {"type": "text", "text": "이 이미지에 표시된 것은 무엇인가요?"},
        ],
    },
]

inputs = processor.apply_chat_template(
    [conversation_1, conversation_2],
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    padding=True,
    return_tensors="pt"
).to(model.device, torch.float16)

generate_ids = model.generate(**inputs, max_new_tokens=1024)
generate_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generate_ids)
]
output = processor.batch_decode(generate_ids_trimmed, skip_special_tokens=True)
print(output)
