2. Create a Flask app in python:

   main.py
   from flask import Flask, jsonify, request
   import torch
   from transformers import AutoTokenizer, AutoModelForCausalLM
   
   app = Flask(__name__)
   
   # Initialize the model and tokenizer
   tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-1.3B")
   model = AutoModelForCausalLM.from_pretrained("EleutherAI/gpt-neo-1.3B")
   
   @app.route('/chatbot', methods=['POST'])
   def chatbot():
       input_text = request.json["input_text"]
       input_ids = tokenizer.encode(input_text, return_tensors='pt')
       response = model.generate(input_ids, max_length=1000, do_sample=True)[0]
       response_text = tokenizer.decode(response)
       return jsonify(response_text=str(response_text))
   662 chars
   18 lines

3. Request the chatbot API:

   main.py
   import requests
   
   url = "http://localhost:5000/chatbot"
   
   payload = {"input_text": "Hello, how are you doing?"}
   
   response = requests.post(url, json=payload)
   
   print("Chatbot Response: ", response.json()["response_text"])
   218 chars
   10 lines

This is just a simple example, you can modify the chatbot function to suit your requirements.
