🧠 Text Detector Model v2 — Fine-Tuned AI vs Human Text Classifier

This model (silentone0725/text-detector-model-v2) is a fine-tuned text classifier that distinguishes between human-written and AI-generated text in English.
It is trained on a large combined dataset of diverse genres and writing styles, built to generalize well on modern large language model (LLM) outputs.

🚀 Usage Example

python

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_name = "silentone0725/text-detector-model-v2"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

text = "This paragraph was likely written by a machine learning model."
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)
pred = torch.argmax(outputs.logits, dim=1).item()

print("🧍 Human" if pred == 0 else "🤖 AI")
