OpenAI Launches GPT-5.5, Touts Progress Toward AI Super App
OpenAI released GPT-5.5 on Thursday, calling it its smartest and most intuitive model yet. Co-founder Greg Brockman said the model brings the company closer to creating a 'super app' that would combine ChatGPT, Codex, and an AI browser into a unified service for enterprise customers. The super app concept is also pursued by Elon Musk for X. GPT-5.5 is designed for agentic coding, knowledge work, mathematics, and scientific research. OpenAI claims it outperforms previous models and competitors like Google's Gemini 3.1 Pro and Anthropic's Claude Opus 4.5 on benchmarks. Chief scientist Jakub Pachocki noted significant short-term improvements, calling the last two years 'surprisingly slow.' Technical staff member Mia Glaese said the model will impact digital defense strategies. Chief research officer Mark Chen highlighted gains in scientific workflows and drug discovery. GPT-5.5 is available to Plus, Pro, Business, and Enterprise users; GPT-5.5 Pro is for Pro, Business, and Enterprise tiers.
