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.

Critics say the cash-strapped system misspent millions of dollars. CSU leaders insist the expense is necessary to prepare students for a changing economy.

In the wake of the long-awaited GPT-5 release, it appears that OpenAI has learned one big lesson: that it does not know its user base.

With new tools and greater autonomy, OpenAI's flagship AI chatbot is more capable, and potentially more dangerous, than ever.

Mental health experts say cases of people forming delusional beliefs after hours with AI chatbots are concerning and offer tips on how to help someone affected.

"You can learn from everywhere, but you have to do it from scratch," ChatGPT's Nick Turley said. "That trait tends to make someone effective at OpenAI."

OpenAI, the maker of ChatGPT, is in talks to sell $6 billion in shares owned by its current and former employees to investors, in a deal that would value the artificial intelligence company at roughly $500 billion, according to two people with knowledge of the discussions.

To many, AI has become a helpful assistant for everyday tasks. But some say chatbots have turned into a personal nightmare, pulling them into a tunnel of isolation and psychosis
