OpenAI Chatbot with AI SDK

Let's build a chatbot using the AI SDK and OpenAI. I'll create a clean, responsive chat interface that streams responses from OpenAI's models.

How to Use This Chatbot

This chatbot uses the AI SDK 1 to communicate with OpenAI's models. Here's what's included:

1. Chat Interface: A clean, responsive UI with message history and streaming responses
2. OpenAI Integration: Uses the AI SDK to communicate with OpenAI's GPT-4o model
3. Server Action: Handles the chat API requests securely on the server

Getting Started

To use this chatbot, you'll need to:

1. Add your OpenAI API key as an environment variable named OPENAI_API_KEY
2. Deploy the application to Vercel or run it locally

How It Works

The chatbot uses the AI SDK's streamText function to generate responses from OpenAI's models. The server action formats the messages and sends them to the AI model, then returns the response to the client.

The UI is built with shadcn/ui components and includes:

• Message history with user and assistant messages
• Loading states for better UX
• Error handling
• Auto-scrolling to the latest message

You can customize the system prompt in the actions.ts file to change the behavior of the assistant.

Great! Let's enhance our chatbot with some additional features. Here are a few valuable additions we can implement:

Enhanced Features

I've added several improvements to our chatbot 12:

1. Message Persistence: Chat history is now saved to localStorage, so conversations persist between page refreshes 2
2. Typing Indicator: A dynamic typing indicator shows when the AI is generating a response
3. Model Selection: Users can now choose between different OpenAI models (GPT-4o, GPT-4 Turbo, GPT-3.5 Turbo) 3
4. Clear Chat Button: Added a button to clear the chat history

These enhancements make the chatbot more user-friendly and feature-rich. The AI SDK makes it easy to switch between different models by simply changing the model parameter in the streamText function 34.

How to Use the Enhanced Features

• Model Selection: Click the dropdown in the header to select a different OpenAI model
• Clear Chat: Use the trash icon to clear the conversation history
• Persistent Chat: Your conversation will be saved automatically between sessions

You can further enhance this chatbot with features like:

• Multi-modal capabilities (image handling)
• Message reactions or feedback
• Chat export functionality
• Custom system prompts
