OpenAI has released the fifth generation of the AI technology behind ChatGPT. The update is being closely watched to see if generative AI is advancing or plateauing.

GPT-5 is the highly anticipated latest installment of a technology that has helped transform global business and culture.

Altman and other OpenAI leaders took questions on Reddit on Friday, a day after the announcement of the new GPT-5 model. A quick glance through the comments revealed how many users preferred how older models like GPT-4.1, GPT-4.5 and 4o handled writing and other tasks. Some said the other models seemed more friendly and conversational than GPT-5.
