What it does

Provides standardized API access to reverse engineered large language models like ChatGPT and Bard, allowing developers to interact with them using a unified OpenAI API format

When to use it

•You need to integrate multiple reverse engineered LLMs into your application without dealing with different APIs
•You want to use ChatGPT or Bard in your project but prefer a standardized API interface
•You're looking for a free alternative to paid LLM APIs with a similar interface

Ready-to-paste prompt

api.ask('What are the implications of AI on modern society?', model='gpt4free')

Heads up: Make sure you have the necessary dependencies installed, including `transformers` and `torch`, as they are required for the API to function properly
