Let’s unpack the future of AI-enabled productivity.🚀
What Is ChatGPT 4 and ChatGPT 4o?
ChatGPT 4 is the fourth iteration of the language model developed by OpenAI, a company recognised as one of the leading names in artificial intelligence. It is more sophisticated than its predecessor, GPT-3.5, providing better reasoning, faster processing, and the ability to use multimodal input, such as images and voice.
In May 2024, OpenAI unveiled a newer version called ChatGPT 4o (the “o” is for “Omni”). Whereas previous models could either understand or generate text, images, or audio — but not both — in real time, ChatGPT 4o can do both. It is designed to create lifelike conversational interactions and is more intelligent, responsive, and intuitive.
