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)

Sample Predictions

Email	Phishing Score	Verdict
"URGENT: Your PayPal account has been suspended!"	99.99%	PHISHING
"Hi team, meeting at 2pm tomorrow"	0.00%	SAFE
"Congratulations! You've won $1,000,000!"	98.66%	PHISHING
"Meeting notes from yesterday attached"	0.00%	SAFE
"Dear valued customer, your package delivery failed"	99.92%	PHISHING
