This tiny model is intended for debugging. It is randomly initialized using the configuration adapted from openai/privacy-filter.

File path	Size
model.safetensors	4.1MB

Example usage:

python

import torch
from transformers import AutoModelForTokenClassification, AutoTokenizer

model_id = "tiny-random/openai-privacy-filter"
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForTokenClassification.from_pretrained(
    model_id,
    dtype=torch.bfloat16,
).to(device)
text = ''
for i in range(10):
    text += f'Contact me at test{i}@example.com or call 555-0000-{i}. '
enc = tokenizer(text, return_tensors='pt').to(device)
with torch.no_grad():
    outputs = model(**enc)
predicted_token_class_ids = outputs.logits.argmax(dim=-1)
predicted_token_classes = [model.config.id2label[token_id.item()] for token_id in predicted_token_class_ids[0]]
print(predicted_token_classes, len(predicted_token_classes))
