Access to the ChatGPT AI is available through the website chatopenaicom or through the mobile app for Android or iPhone. To use ChatGPT, you will need to sign up for a free OpenAI account. Once you have an account, you can click on the New Chat button at the topleft corner of the page and type in a question or prompt to start using ChatGPT. As of January 5th, 2024, ChatGPT Plus subscribers have access to GPT4 with a usage cap of 40 messages every 3 hours. The dialogue format of ChatGPT makes it possible for the AI to answer follow-up questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. Additionally, ChatGPT now has the capability to see, hear, and speak, and users can show ChatGPT images to start a chat or analyze complex data. Voice and image capabilities have also been introduced, allowing for a more intuitive type of interface.
