  * Max seq len: 256
  
## Usage

```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("visolex/phobert-spam-classification")
model = AutoModelForSequenceClassification.from_pretrained("visolex/phobert-spam-classification")

text = "Chỉ PR thương hiệu chứ không review thật."
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)
pred = model(**inputs).logits.argmax(dim=-1).item()
label_map = {0: "NO-SPAM",1: "SPAM-1",2: "SPAM-2",3: "SPAM-3"}
print(label_map[pred])
```
