GPT-4 Chat UI

Build your own GPT-4 frontend with this open source Next.js template! Simply add your OpenAI API key and you're good to go! Don't have early access to GPT-4? Replace "gpt-4" with "gpt-3.5-turbo" in pages/api/chat.js. Can't wait to see what you build with this! Note: due to insanely high traffic, I have downgraded this to GPT 3.5 until further notice.
