“This model is a real step forward towards the kind of computing that we expect in the future — but it is one step, and we expect to see many in the future,” Brockman said. “It’s a faster, sharper thinker for fewer tokens compared to something like 5.4. So this means that there’s just more frontier AI available for businesses and for consumers, which is part of our goal.”

Brockman also said that the model was an additional step toward creating a “super app” — a multi-purpose, Swiss Army knife of a program — which Brockman and co-founder Sam Altman have previously discussed launching. The co-founders envision combining ChatGPT, Codex, and AI browser into one unified service that can aid enterprise customers. Notably, the “super app” concept is also a hot topic with Altman rival (and former OpenAI colleague) Elon Musk, who has said he wants to turn X into its own so-called super app.

OpenAI released its last model only last month, with a previous release in December and, before that, November. The company has continued to churn out new models at a crisp pace, a trend that company staff said should be expected to continue for the foreseeable future. “We see pretty significant improvements in the short term, extremely significant improvements in the medium term,” said Jakub Pachocki, OpenAI’s chief scientist. “In fact, I would say, like, I think the last two years have been surprisingly slow.”

According to OpenAI, GPT-5.5 is designed to be useful across a broad array of categories, including foundational enterprise areas like agentic coding and knowledge work, but also in more experimental AI applications like mathematics and scientific research. The company also released data Thursday showing the model’s superior performance across a range of benchmarks. Compared to its previous 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.
