"""
TootBot is a Python class that provides functionality to generate and post tweets
on Mastodon. The class uses OpenAI's generative language model to generate the
content for the tweets. The tweets can be generated from a given topic, and the
class allows for customization of several parameters, such as the number of tweets
to generate and the frequency of including images.
TootBot acts as a bot that can create Twitter-like posts, or "toots", from given inputs.
It includes methods for adding custom images and text to a given image, generating text completions
and titles for articles, and classifying text as "failed" or "not failed". Additionally, it includes
methods for generating news articles from prompts and rephrasing existing text in a news article style,
as well as extracting keywords from text. The class relies on several third-party libraries and models,
including the Pillow and OpenAI libraries, the Stable Diffusion image generation model, and several text
classification and keyword extraction models. Users can customize certain parameters of the models used
by the bot, such as the device type and data type for the image generation model, and the model IDs for
the text classification and keyword extraction models. The Tootbot class provides a powerful toolkit for
generating engaging content for social media and other purposes.
To use the TootBot class, the user needs to have a Mastodon account and an OpenAI
API key. The class provides methods to log in to Mastodon, generate and save tweets
to a CSV file, create images to accompany the tweets, and post the tweets to Mastodon.
The class requires the installation of several Python packages, including
openai, numpy, pandas, and mastodon.py.

Date: April 7, 2023
Example usage:
# Instantiate the TootBot class with an OpenAI API key and a generative language model
my_bot = TootBot(model='gpt-4', api_key='12345')
# Initialize all models to allow the model to function
my_bot.init_models(diffusion_model="stabilityai/stable-diffusion-2-1-base",
dtype="float32", device="cuda")
# Log in to Mastodon using a username and password
my_bot.mastodon_login(username='my_username', password='my_password',
redirect_uri='http://localhost:3000/', to_file='usercred.secret')
# Generate and post tweets on a given topic
my_bot.run(topic='artificial intelligence', num_responses=50)
