OpenAI has just released GPT-5, its most advanced AI model yet, now available to all ChatGPT users and developers worldwide. CEO Sam Altman calls it a dramatic leap forward—like upgrading to the first iPhone with a Retina display.
Smarter, faster, and 45% more accurate than GPT-4o, GPT-5 feels like talking to a PhD-level expert. It’s the best in the world at coding, writing, health care, and more—building apps, and games in minutes.
A new reasoning router adapts automatically for complex questions—no confusing menus. And it’s free for everyone, with Pro and Enterprise plans for heavier workloads.
GPT-5—your on-demand expert in anything, anytime.
