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, Hugging Face, or using LangChain with just a few lines of code.

upstash

You will need to set up an upstash account and create a Redis Database. Only takes a few clicks!

Remember to update your environment variables (UPSTASH_URL, UPSTASH_KEY) in the .env file with the appropriate credentials provided during the setup process.

Clerk

You will need to set up a Clerk account and create a Clerk application. This also only takes a few clicks!

Remember to update your environment variables (NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY, CLERK_SECRET_KEY) in the .env file with the appropriate credentials provided during the setup process.

Running locally

You will need to use the environment variables defined in .env.example to run Next.js AI Chatbot. It's recommended you use Vercel Environment Variables for this, but a .env file is all that is necessary.

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.

1. Install Vercel CLI: npm i -g vercel
2. Link local instance with Vercel and GitHub accounts (creates .vercel directory): vercel link
3. Download your environment variables: vercel env pull

pnpm install
pnpm dev

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