+# 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
