Introduction to Chatbots and Their Use Cases

• What's a Chatbot?: At its core, a chatbot is like a virtual assistant. It's a program that chats with you, answering questions or helping out with tasks. They're often found on websites, apps, or even in messaging platforms.
• Why Use Them?: Chatbots are super handy for businesses. They can handle customer questions at any hour, help users navigate a website, or even take food orders. For users, they offer instant answers without waiting on hold or searching through FAQs.

Basics of Integrating LLMs with Chat

• Why LLMs?: Remember those old chatbots that could only answer a handful of questions? With LLMs, chatbots got a major upgrade. They can understand context, handle a wider range of queries, and give more human-like responses.
• How's It Done?: It starts by connecting a chatbot interface (where users type their questions) to an LLM like GPT. When a user asks something, the chatbot sends the question to the LLM, gets the answer, and then shows it to the user. It's like the LLM is the brain of the chatbot.

High-Level Overview of the Chatbot Architecture

• The Frontend: This is where users interact. It could be a chat window on a website, an app, or even a messaging platform. It's all about the user experience here.
• The Backend: This is where the magic happens. Once a user sends a message, it goes to the server. Here, the message is processed, sent to the LLM, and the response is fetched.
• The LLM Integration: This is the part where the chatbot connects to the LLM (like GPT). The LLM takes in the user's message, thinks for a split second, and sends back a response.
