OpenAI launches GPT-5.5 as it pushes toward 'super app' vision

OpenAI on Thursday released GPT-5.5, its newest AI model, which the company asserts is its smartest and most intuitive model to date. Greg Brockman, OpenAI’s co-founder and president, stated that the release brings the company closer to creating a super app—which he defined as a multi-purpose, unified software application. Brockman and co-founder Sam Altman envision this application combining ChatGPT, Codex, and an AI browser into a single service for enterprise customers. Brockman described the model as a step toward more agentic computing, meaning AI that is capable of performing autonomous tasks. While Brockman noted that the company expects to see many steps forward in the future, he described this release as a single step.

The release of GPT-5.5 continues a rapid pace of model releases for OpenAI, which previously launched models last month, in December, and in November. Staff indicated that this rapid pace should be expected to continue for the foreseeable future. Jakub Pachocki, OpenAI’s chief scientist, noted that the company expects to see significant improvements in the short term and extremely significant improvements in the medium term, adding that he considered the last two years to have been surprisingly slow. According to OpenAI, GPT-5.5 is a faster and sharper thinker that uses fewer tokens than its previous 5.4 version. Brockman, the co-founder and president, stated: “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.” The company released benchmark data showing that GPT-5.5 consistently scores higher than its own previous models and those of its main competitors:

• It outperforms Google’s Gemini 3.1.
• It scores higher than Anthropic’s Claude Opus 4.5.

The model is designed for utility across enterprise tasks like agentic coding, as well as scientific and technical research workflows. Mark Chen, OpenAI’s chief research officer, asserted that GPT-5.5 shows meaningful gains in these research workflows and could help expert scientists make progress. During a press briefing, OpenAI staff also addressed how the model relates to cybersecurity, specifically when asked if GPT-5.5 would have capabilities similar to Mythos, a cybersecurity tool developed by competitor Anthropic. Mythos has experienced controversy in recent days due to a report of unauthorized access to the program. Mia Glaese, a member of OpenAI’s technical staff, stated that the company has a strong and longstanding strategy for its approach to cyber and has refined a durable approach to rolling out models safely.

Why it matters

OpenAI’s release of GPT-5.5 is a strategic move to consolidate its various AI tools into a unified super app, signaling a shift toward more agentic, autonomous computing for enterprise and consumer users.
