OpenAI has released GPT-5.5, its newest artificial intelligence model, describing it as the company’s most capable and intuitive model to date and a step towards its stated goal of building an AI superapp that consolidates its core products into a single unified service.
OpenAI co-founder and president Greg Brockman said the release was an additional step towards building a superapp—a multi-purpose, unified programme combining ChatGPT, Codex, and an AI browser into one service primarily aimed at enterprise customers, reports Techcrunch.
OpenAI released its previous model, GPT-5.4, only last month, with prior releases in December and November. According to OpenAI, GPT-5.5 is designed for a broad array of applications, including agentic coding, enterprise knowledge work, mathematics, and scientific research.
GPT-5.5 is available from Thursday to Plus, Pro, Business, and Enterprise users in ChatGPT, while a GPT-5.5 Pro tier is rolling out to Pro, Business, and Enterprise subscribers. OpenAI’s published benchmark data shows the model outperforming recent models from rivals including Google and Anthropic across a range of evaluations.
