• ChatGPT was created by OpenAI, an AI research company based in San Francisco, and released publicly on November 30, 2022.
• ChatGPT is an artificial intelligence (AI) chatbot that can understand and generate natural language text:

How it works
ChatGPT is trained on large amounts of text data, including Wikipedia articles and research papers, using a transformer algorithm. It uses machine learning algorithms to process and analyze the data, and then generate responses to user inquiries.
What it can do
ChatGPT can:
Respond to questions
Compose written content, such as articles, social media posts, essays, code, and emails
Understand human language as it is spoken and written
How to use it
Users can ask questions or make requests in the form of prompts, and ChatGPT will respond. For example, you can ask it to explain how climate change affects endangered species, or write you a poem.
Features
ChatGPT is free to use and has gained popularity as an alternative to traditional search engines and as a tool for AI writing.
Limitations
ChatGPT can be prone to "hallucinations", or nonsensical answers to factual questions. It's also important to use ChatGPT with critical thinking, as it has many blind spots.
