Did you know you don't need to import any special libraries to generate text via an LLM?
All you need is an API key from the LLM platform, a Python environment, and the requests library. Then in a few lines of code you can get started.
Quick start!
If you are working from the command-line, you can run any of the scripts below with a simple call:
OPENAI_API_KEY=yourkeygoeshere python3 script.py
OR, you can add OPENAI_API_KEY=yourkeygoeshere to a .env file in the same directory, and add this code to the top of your script:
from dotenv import load_dotenv
load_dotenv()
OR, if you're using Google Colab, click the 🔑 icon in the left sidebar and follow the resulting instructions.
