# **coreOCR-7B-050325-preview**

> The **coreOCR-7B-050325-preview** model is a fine-tuned version of **Qwen/Qwen2-VL-7B**, optimized for **Document-Level Optical Character Recognition (OCR)**, **long-context vision-language understanding**, and **accurate image-to-text conversion with mathematical LaTeX formatting**. Designed with a focus on high-fidelity visual-textual comprehension, this model enhances document parsing, structured data extraction, and complex visual reasoning.

# Key Enhancements

* **Advanced Document-Level OCR**: Accurately processes and extracts structured text from complex, multi-page documents including invoices, forms, and research papers.

* **Enhanced Long-Context Vision-Language Understanding**: Supports long-text retrieval and reasoning from documents and multimedia inputs, including dense text blocks, diagrams, and math content.

* **SoTA Understanding Across Image Resolutions**: Achieves state-of-the-art results on visual benchmarks including MathVista, DocVQA, RealWorldQA, and MTVQA.

* **Video Comprehension up to 20+ minutes**: Capable of high-quality video-based question answering, dialogue generation, and content summarization from long video sequences.

* **Device Control via Visual Commands**: With complex reasoning and perception capabilities, it can be integrated with devices like mobile phones or robots for visually grounded automation.

# Quick Start with Transformers

```python
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info

model = Qwen2VLForConditionalGeneration.from_pretrained(
    "prithivMLmods/coreOCR-7B-050325-preview", torch_dtype="auto", device_map="auto"
)

processor = AutoProcessor.from_pretrained("prithivMLmods/coreOCR-7B-050325-preview")

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
            },
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to("cuda")

generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
```

# Intended Use

This model is intended for:

* Document analysis and OCR from scanned images, PDFs, and camera input.
* Image-based question answering (e.g., educational content, diagrams, receipts).
* Math problem solving and LaTeX text generation from handwritten or printed math content.
* Long-context vision-text applications such as multi-slide document retrieval and dense information extraction.
* Multilingual OCR workflows for cross-lingual business documents and global data digitization.
* AI agents for mobile/robotic interaction through visual context.

# Limitations

* Performance may degrade on extremely noisy or low-resolution images.
* Not suitable for real-time inference on edge devices due to model size and memory demands.
* While multilingual, performance on low-resource or rare scripts may vary.
* Not optimized for high-speed processing of video streams in constrained environments.
* Contextual understanding depends on visual tokenization parameters; improper configuration may affect output quality.
* Outputs may occasionally include hallucinations or incomplete answers in long-context queries.
