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

OpenAI on Thursday launched GPT-5.5, its latest AI mannequin, which the corporate calls its “smartest and most intuitive to make use of mannequin” but. The algorithm comes with elevated capabilities in a mess of areas, with OpenAI co-founder and president Greg Brockman claiming that it additionally brings the corporate one step nearer to the creation of OpenAI’s “tremendous app.”

On a name with journalists, Brockman stated that the brand new mannequin was a giant development “in direction of extra agentic and intuitive computing.”

“This mannequin is an actual step ahead in direction of the type of computing that we anticipate sooner or later — however it’s one step, and we anticipate to see many sooner or later,” Brockman stated. “It’s a quicker, sharper thinker for fewer tokens in comparison with one thing like 5.4. So because of this there’s simply extra frontier AI obtainable for companies and for shoppers, which is a part of our aim.”

Brockman additionally stated that the mannequin was a further step towards making a “tremendous app” — a multi-purpose, Swiss Military knife of a program — which Brockman and co-founder Sam Altman have beforehand mentioned launching. The co-founders envision combining ChatGPT, Codex, and AI browser into one unified service that may support enterprise prospects. Notably, the “tremendous app” idea can be a scorching subject with Altman rival (and former OpenAI colleague) Elon Musk, who has stated he desires to show X into its personal so-called tremendous app.

OpenAI launched its final mannequin solely final month, with a earlier launch in December and, earlier than that, November. The corporate has continued to churn out new fashions at a crisp tempo, a development that firm workers stated must be anticipated to proceed for the foreseeable future. “We see fairly important enhancements within the quick time period, extraordinarily important enhancements within the medium time period,” stated Jakub Pachocki, OpenAI’s chief scientist. “In reality, I might say, like, I feel the final two years have been surprisingly gradual.”

In keeping with OpenAI, GPT-5.5 is designed to be helpful throughout a broad array of classes, together with foundational enterprise areas like agentic coding and information work, but additionally in additional experimental AI purposes like arithmetic and scientific analysis. The corporate additionally launched knowledge Thursday exhibiting the mannequin’s superior efficiency throughout a spread of benchmarks. In comparison with its earlier fashions, and to fashions from rivals Google and Anthropic (like Gemini 3.1 Professional and Claude Opus 4.5), 5.5 persistently scores larger, in response to OpenAI.

OpenAI’s rivalry with Anthropic is rarely removed from dialogue, and GPT-5.5 provided one other alternative for the 2 firms to check themselves to 1 one other. One reporter throughout the press briefing requested if GPT 5.5. would have capabilities just like Mythos, the cybersecurity device lately introduced by Anthropic. (Mythos has skilled controversy in latest days as a result of a report of unauthorized entry to this system.) Mia Glaese, a member of OpenAI’s technical workers, stated that GPT-5.5 would have a big impression on the corporate’s strategy to deploying its fashions towards digital protection. “We have now a powerful and longstanding technique for our strategy to cyber, and we’ve refined a sturdy strategy to rolling out fashions safely,” Glaese stated.

Mark Chen, chief analysis officer at OpenAI, stated that GPT-5.5 was higher at navigating laptop work than its predecessors, and likewise stated that the mannequin “reveals significant features on scientific and technical analysis workflows,” noting that the corporate feels it might actually “assist skilled scientists make progress.” Chen additionally stated it might help with drug discovery, an space that has proven elevated trade curiosity over the previous couple of years.

GPT 5.5 is broadly obtainable beginning Thursday, in response to OpenAI. The corporate says that the mannequin is deploying to Plus, Professional, Enterprise, and Enterprise customers in ChatGPT, whereas 5.5 Professional is headed to Professional, Enterprise, and Enterprise customers.
