**ArmorOCR** is a two-stage framework for **grounded adversarial OCR perception** built on Qwen3-VL-8B-Instruct. It enables single-pass inference on the original image, without any inference-time visual transformations or tool assistance.

📖 For training details, the AdvSpot benchmark, and evaluation scripts, please visit the [GitHub repo](https://github.com/ant-research/ArmorOCR).

## Quickstart

```bash
pip install transformers==4.57.1 accelerate
```

```python
from transformers import Qwen3VLForConditionalGeneration, AutoProcessor

model = Qwen3VLForConditionalGeneration.from_pretrained(
    "inclusionAI/ArmorOCR", dtype="auto", device_map="auto",
)
processor = AutoProcessor.from_pretrained("inclusionAI/ArmorOCR")

messages = [{
    "role": "user",
    "content": [
        {"type": "image", "image": "path/to/image.png"},
        {"type": "text",
         "text": ("Please identify the text in the image. "
                  "Put your reasoning inside <analyze></analyze> "
                  "and your final recognized text inside <answer></answer>.")},
    ],
}]

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

out = model.generate(**inputs, max_new_tokens=256)
trimmed = [o[len(i):] for i, o in zip(inputs.input_ids, out)]
print(processor.batch_decode(trimmed, skip_special_tokens=True))
```
