Model Providers

This template ships with OpenAI gpt-3.5-turbo as the default. However, thanks to the Vercel AI SDK, you can switch LLM providers to Anthropic, Cohere, Hugging Face, or using LangChain with just a few lines of code.

Running locally

You will need to use the environment variables defined in .env.example to run Next.js AI Chatbot.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

pnpm install
pnpm dev

Your app template should now be running on localhost:3000.
