Example Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("diwakartiwari/mistral-7b-financial-sentiment")
base_model = AutoModelForCausalLM.from_pretrained("mistralai/Mistral-7B-v0.1")
model = PeftModel.from_pretrained(base_model, "diwakartiwari/mistral-7b-financial-sentiment")

# Prepare prompt
prompt = "<s>[INST] Analyze the financial sentiment of this statement: Company reported record profits [/INST] "

# Generate response
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=20)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

# Expected Output: "The financial sentiment is positive."
