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.

C lose followers of OpenAI's model releases are probably tired of hearing about GPT-5, the next big step in the company's line of flagship large language models. It's been expected seemingly all year. But the hints are getting very strong.

In an interview, the head of ChatGPT says ‘we have to give people some level of predictability when there’s a major change.’ After the backlash to replacing its 4o model with GPT-5, OpenAI will no longer get rid of old models without a heads up.
