How to Get Started with the Model

from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("roma2025/FinLlama-3-8B")
tokenizer = AutoTokenizer.from_pretrained("roma2025/FinLlama-3-8B")

def get_sentiment_score(model, tokenizer, text):
    inputs = tokenizer(text, return_tensors='pt', padding=True, truncation=True, max_length=75)
    with torch.no_grad():
        outputs = model(**inputs)
        logits = outputs.logits
    probabilities = F.softmax(logits, dim=-1)
    sentiment_score = torch.argmax(probabilities, dim=-1).item()
    return sentiment_score, probabilities

# Example usage
text = "Determine the sentiment of the financial news as negative, neutral or positive:
The stock market is going up!
Sentiment:"

sentiment_score, probabilities = get_sentiment_score(model, tokenizer, text)
