A quick-start template using the OpenAI Assistants API with Next.js.
git clone https://github.com/openai/openai-assistants-quickstart.git
cd openai-assistants-quickstart
2. Set your OpenAI API key
export OPENAI_API_KEY="sk_..."
(or in .env.example
and rename it to .env
).
npm install
npm run dev
5. Navigate to http://localhost:3000.
This project is intended to serve as a template for using the Assistants API in Next.js with streaming, tool use (code interpreter and file search), and function calling. While there are multiple pages to demonstrate each of these capabilities, they all use the same underlying assistant with all capabilities enabled.
The main logic for chat will be found in the Chat
component in app/components/chat.tsx
, and the handlers starting with api/assistants/threads
(found in api/assistants/threads/...
). Feel free to start your own project and copy some of this logic in! The Chat
component itself can be copied and used directly, provided you copy the styling from app/components/chat.module.css
as well.
