Usage

ONNX Runtime (recommended, low memory)

from optimum.onnxruntime import ORTModelForSequenceClassification
from transformers import AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("xanderabim/fraudfoxai-phishing")
model = ORTModelForSequenceClassification.from_pretrained("xanderabim/fraudfoxai-phishing")

inputs = tokenizer("URGENT: Verify your account now!", return_tensors="np", truncation=True)
outputs = model(**inputs)

PyTorch

from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("xanderabim/fraudfoxai-phishing")
model = AutoModelForSequenceClassification.from_pretrained("xanderabim/fraudfoxai-phishing")

inputs = tokenizer("URGENT: Verify your account now!", return_tensors="pt", truncation=True)
outputs = model(**inputs)
