Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

repo = "AtliQ-Technologies/guardex-distilbert-safety"
tok = AutoTokenizer.from_pretrained(repo)
model = AutoModelForSequenceClassification.from_pretrained(repo)

enc = tok("text to check", return_tensors="pt", truncation=True, max_length=128)
with torch.no_grad():
    logits = model(**enc).logits
print(model.config.id2label[int(logits.argmax())])  # "safe" or "unsafe"
