Usage

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

# Load model
base_model = "meta-llama/Meta-Llama-3.1-8B-Instruct"
tokenizer = AutoTokenizer.from_pretrained(base_model)
model = AutoModelForCausalLM.from_pretrained(
    base_model,
    device_map="auto",
    torch_dtype=torch.bfloat16
)
model = PeftModel.from_pretrained(model, "manaspros/indian-receipt-parser-v2")

# Prepare receipt
receipt_text = """
Thank you for your purchase from Zomato

Date: November 15, 2025
Subtotal: ₹450
Tax (18%): ₹81
Total: ₹531
"""

messages = [
    {
        "role": "system",
        "content": "You are a financial receipt parser specialized in Indian vendors. Extract vendor name, amount, date, and category from receipts. Return ONLY valid JSON."
    },
    {
        "role": "user",
        "content": receipt_text
    }
]

# Generate
input_text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.1)
response = tokenizer.decode(outputs[0][inputs['input_ids'].shape[1]:], skip_special_tokens=True)

print(response)
# Output: {"vendor": "Zomato", "amount": 531.0, "date": "2025-11-15", "category": "dining", ...}

Output Format

  "tax": 0.0,
  "currency": "INR",
  "confidence": 0.95
}

Performance Metrics
