# Finetuned RADAR — AI Text Detector

Fine-tuned version of [TrustSafeAI/RADAR-Vicuna-7B](https://huggingface.co/TrustSafeAI/RADAR-Vicuna-7B) 
(RoBERTa classifier) via LoRA for binary AI-generated text detection.

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_id = "elisabeth-pl-pl/Finetuned-RADAR-binary-classification"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id)

text = "Your text here"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=512)
with torch.no_grad():
    logits = model(**inputs).logits
pred = logits.argmax(-1).item()
print("machine" if pred == 0 else "human")
```

## Labels
- `0` — machine-generated
- `1` — human-written
