What it does
This is OpenAI's own Python library. It lets programmers send requests to OpenAI's models, the same family behind ChatGPT, from their own apps and scripts.
With a few lines of code, a program can send instructions and text to a model and get a reply back. It handles details like account keys and connections. Using the models requires an OpenAI account and is usually paid.
Who it's for
