Explore Workers AI Models Using a Jupyter Notebook

Last reviewed:

A handy way to explore all of the models available on Workers AI is to use a Jupyter Notebook.

You can download the Workers AI notebook or view the embedded notebook below.

​​ Explore the Workers AI API using Python

Workers AI allows you to run machine learning models, on the Cloudflare network, from your own code – whether that be from Workers, Pages, or anywhere via REST API.

This notebook will explore the Workers AI REST API using Python and the requests library.

import sys
!{sys.executable} -m pip install requests python-dotenv

​​ Configuring your environment

To use the API you’ll need your Cloudflare Account ID (head to Workers & Pages > Overview > Account details > Account ID) and a Workers AI enabled API Token.

If you want to add these files to your environment, you can create a new file named .env

if "CLOUDFLARE_API_TOKEN" in os.environ:
api_token = os.environ["CLOUDFLARE_API_TOKEN"]
api_token = getpass("Enter you Cloudflare API Token")
if "CLOUDFLARE_ACCOUNT_ID" in os.environ:
account_id = os.environ["CLOUDFLARE_ACCOUNT_ID"]
account_id = getpass("Enter your account id")

​​ Text Generation

Explore all Text Generation Models

model = "@cf/meta/llama-3-8b-instruct"
response =
headers={"Authorization": f"Bearer {api_token}"},
json={"messages": [
{"role": "system", "content": "You are a productivity assistant for users of Jupyter notebooks for both Mac and Windows users. Respond in Markdown."},
{"role": "user", "content": "How do I use keyboard shortcuts to execute cells?"}
inference = response.json()

Great question! 😊

​​ Mac Users:

To execute cells using keyboard shortcuts on a Mac, you can use the following combinations:

Ctrl + EnterExecute the current cell.
Shift + EnterExecute the current cell and move to the next cell.
Cmd + EnterExecute the current cell and move to the next cell. (Only works in Jupyter Notebook 1.0 and later.)

​​ Windows Users:

On Windows, you can use the following keyboard shortcuts to execute cells:

Ctrl + EnterExecute the current cell.
Shift + EnterExecute the current cell and move to the next cell.
Shift + Ctrl + EnterExecute the current cell and move to the next cell without leaving the cell.


  • You can also use the F5 key to execute the current cell on both Mac and Windows.
