SAN FRANCISCO (AP) — OpenAI on Thursday released the fifth generation of the artificial intelligence technology that powers ChatGPT, a product update that’s being closely watched as a measure of whether generative AI is advancing rapidly or hitting a plateau.
GPT-5 arrives more than two years after the March 2023 release of GPT-4, bookending a period of intense commercial investment, hype and worry over AI’s capabilities.
In anticipation, rival Anthropic released the latest version of its own chatbot, Claude, earlier in the week.

Expectations are high for the newest version of OpenAI’s flagship model because the San Francisco company has long positioned its technical advancements as a path toward artificial general intelligence, or AGI, a technology that is supposed to surpass humans at economically valuable work.
It is also trying to raise huge amounts of money to get there, in part to pay for the costly computer chips and data centers needed to build and run the technology.
OpenAI Sam Altman described the new model as a “significant step along our path to AGI” but mostly focused on its usability to the 700 million people he says use ChatGPT each week.
“It’s like talking to an expert — a legitimate PhD-level expert in anything, any area you need, on demand,” Altman said at a launch event livestreamed Thursday.
OpenAI started in 2015 as a nonprofit research laboratory to safely build AGI and has since incorporated a for-profit company with a valuation that has grown to $300 billion. The company has tried to change its structure since the nonprofit board ousted its Altman in Nov. 2023. He was reinstated days later and continues to lead OpenAI.

It has run into hurdles escaping its nonprofit roots, including scrutiny from the attorneys general in California and Delaware, who have oversight of nonprofits, and a lawsuit by Elon Musk, an early donor to and founder of OpenAI.
Most recently, OpenAI has said it will turn its for-profit company into a public benefit corporation, which must balance the interests of shareholders and its mission.
