# exo provides an API that aims to be a drop-in replacements for the ChatGPT-API.
# This example shows how you can use the API first without streaming and second with streaming.
# This works the same in a single-node set up and in a multi-node setup.
# You need to start exo before running this by running `python3 main.py`.
