## Usage

```python
from setfit import SetFitModel

# Load the model
model = SetFitModel.from_pretrained("loganh274/nlp-testing-setfit")

# Single prediction
text = "This product exceeded my expectations!"
prediction = model.predict([text])
print(f"Sentiment: {prediction[0]}")

# Batch prediction
texts = [
    "Amazing quality, highly recommend!",
    "It's okay, nothing special.",
    "Terrible experience, very disappointed.",
]
predictions = model.predict(texts)
probabilities = model.predict_proba(texts)

for text, pred, prob in zip(texts, predictions, probabilities):
    print(f"Text: {text}")
    print(f"  Prediction: {pred}, Confidence: {max(prob):.2%}")
```

## Label Mapping
