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.

OpenAI launched its most advanced language model Thursday with the release of GPT-5, a flagship product the company says will enhance ChatGPT as it reportedly nears a $500 billion valuation and aims to stave off competitors in Google, Anthropic and more.

OpenAI on Thursday released GPT-5, unveiling a new version of the artificial intelligence model that fuels popular chatbot ChatGPT. The product will be made immediately available to users, including customers who use the company's cost-free options, OpenAI said.
