🚀 Example Inference

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tokenizer = AutoTokenizer.from_pretrained("kishankachhadiya/debarta-text-classifier")
model = AutoModelForSequenceClassification.from_pretrained("kishankachhadiya/debarta-text-classifier")

text = "This text was likely written by an AI model."
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)
probs = torch.nn.functional.softmax(outputs.logits, dim=1)
print(probs)
