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.

Rest assured, GPT-5 is launching today. When it's available, the ChatGPT homepage should have a message introducing the new model, which reads: "Introducing GPT-5: ChatGPT now has our smartest, fastest, most useful model yet, with thinking built in - so you get the best answer, every time."
