OpenAI has officially launched GPT-5, its most advanced AI model to date. In a pre-briefing, Sam Altman shared that once he tried GPT-5 he had a hard time going back to GPT-4, likening the revert to using an old iPhone.
Designed to be more useful, more accurate and more human than any version before it, this is by far OpenAI's smartest and most efficient model.
GPT-5 is now rolling out in ChatGPT and the API, with the company describing it as a “unified system” built to deliver the best possible answer every time; no model switching required. This marks a major shift from the current GPT-4/4o experience and introduces a more seamless way to interact with AI.
