While ChatGPT is easy to use on the surface, many complex computations that are customized to each user are happening behind the scenes. Large Language Models (LLMs) rely on gigantic AI neural networks that can process and generate human-like text, analyze images, and even speak on their own. Here's how it works.

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.

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.

"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."

One source said the maker of ChatGPT was looking at a growing its office space footprint outside of San Francisco.

OpenAI’s Sam Altman didn’t build his fortune off his modest CEO salary. The tech titan worth $1.9 billion instead made critical early investments in Uber, Airbnb, and Reddit that yielded hundreds of millions of dollars.

OpenAI says it has tweaked ChatGPT to ensure the model responds appropriately when a user shows distress.
