Introduction

VARCO-VISION-2.0-1.7B-OCR is a lightweight yet powerful OCR-specialized model derived from VARCO-VISION-2.0-1.7B, designed to deliver efficient and accurate text recognition in real-world scenarios. Unlike conventional vision-language models (VLMs) that primarily focus on transcribing visible text, this model performs both recognition and spatial localization by detecting bounding boxes around each character, enabling structured, layout-aware OCR outputs.

The model supports both Korean and English, making it well-suited for multilingual environments where mixed-script documents are common. Each recognized character is paired with its precise position in the image, formatted as <char>{characters}</char><bbox>{x1}, {y1}, {x2}, {y2}</bbox>, where the coordinates correspond to the top-left (x1, y1) and bottom-right (x2, y2) corners of the character's bounding box.

While VARCO-VISION-2.0-14B demonstrates strong OCR capabilities as part of its broader multimodal reasoning skills, deploying such a large model for single-task use cases can be computationally inefficient. VARCO-VISION-2.0-1.7B-OCR addresses this with a task-optimized design that retains high accuracy while significantly reducing resource requirements, making it ideal for real-time or resource-constrained applications.

Usage

To use this model, we recommend installing transformers version 4.53.1 or higher. Additionally, for best results, we *recommend upscaling input images to a minimum resolution of 2,304*** on the longer side if they are smaller.

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

model_name = "NCSOFT/VARCO-VISION-2.0-1.7B-OCR"
model = LlavaOnevisionForConditionalGeneration.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    attn_implementation="sdpa",
    device_map="auto",
)
processor = AutoProcessor.from_pretrained(model_name)

image = Image.open("file:///path/to/image.jpg")

# Image upscaling for OCR performance boost
w, h = image.size
target_size = 2304
if max(w, h) < target_size:
    scaling_factor = target_size / max(w, h)
    new_w = int(w * scaling_factor)
    new_h = int(h * scaling_factor)
    image = image.resize((new_w, new_h))

conversation = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": image},
            {"type": "text", "text": "<ocr>"},
        ],
    },
]

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)
