OpenAI releases GPT-5.5, bringing company one step closer to an AI ‘superapp’

OpenAI connected Thursday released GPT-5.5, its newest AI model, which the institution calls its “smartest and astir intuitive to usage model” yet. The algorithm comes with accrued capabilities successful a multitude of areas, with OpenAI co-founder and president Greg Brockman claiming that it besides brings the institution 1 measurement person to the instauration of OpenAI’s “superapp.”

On a telephone with journalists, Brockman said that the caller exemplary was a large advancement “towards much agentic and intuitive computing.”

“This exemplary is simply a existent measurement guardant towards the benignant of computing that we expect successful the aboriginal — but it is 1 step, and we expect to spot galore successful the future,” Brockman said. “It’s a faster, sharper thinker for less tokens compared to thing similar 5.4. So this means that there’s conscionable much frontier AI disposable for businesses and for consumers, which is portion of our goal.”

Brockman besides said that the exemplary was an further measurement toward creating a “superapp” — a multi-purpose, Swiss Army weapon of a programme — which Brockman and co-founder Sam Altman person antecedently discussed launching. The co-founders envision combining ChatGPT, Codex, and AI browser into 1 unified work that tin assistance endeavor customers. Notably, the “superapp” conception is also a blistery topic with Altman rival (and erstwhile OpenAI colleague) Elon Musk, who has said helium wants to crook X (formerly Twitter) into its ain alleged superapp.

OpenAI released its past model lone past month, with a erstwhile merchandise successful December and, earlier that, November. The institution has continued to churn retired caller models astatine a crisp pace, a inclination that institution unit said should beryllium expected to proceed for the foreseeable future. “We spot beauteous important improvements successful the abbreviated term, highly important improvements successful the mean term,” said Jakub Pachocki, OpenAI’s main scientist. “In fact, I would say, like, I deliberation the past 2 years person been amazingly slow.”

According to OpenAI, GPT-5.5 is designed to beryllium utile crossed a wide array of categories, including foundational endeavor areas similar agentic coding and cognition work, but besides successful much experimental AI applications similar mathematics and technological research. The institution besides released information Thursday showing the model’s superior show crossed a scope of benchmarks. Compared to its erstwhile models, and to models from competitors Google and Anthropic (like Gemini 3.1 Pro and Claude Opus 4.5), 5.5 consistently scores higher, according to OpenAI.

OpenAI’s rivalry with Anthropic is ne'er acold from discussion, and GPT-5.5 offered different accidental for the 2 companies to comparison themselves to 1 another. One newsman during the property briefing asked if GPT 5.5. would person capabilities akin to Mythos, the cybersecurity instrumentality precocious announced by Anthropic. (Mythos has experienced contention successful caller days owed to a study of unauthorized entree to the program.) Mia Glaese, a subordinate of OpenAI’s method staff, said that GPT-5.5 would person a important interaction connected the company’s attack to deploying its models towards integer defense. “We person a beardown and agelong lasting strategy for our attack to cyber, and we’ve refined a durable attack to rolling retired models safely,” Glaese said.

Mark Chen, main probe serviceman astatine OpenAI, said that GPT-5.5 was amended astatine navigating machine enactment than its predecessors, and besides said that the exemplary “shows meaningful gains connected technological and method probe workflows,” noting that the institution consciousness it could truly “help adept scientists marque progress.” Chen besides said it could assistance with cause discovery, an country that has shown increased manufacture interest implicit the past fewer years.

GPT 5.5. is wide disposable starting Thursday, according to OpenAI. The institution says that the exemplary is deploying to Plus, Pro, Business, and Enterprise users successful ChatGPT, portion 5.5 Pro is headed to Pro, Business, and Enterprise users.
