San Francisco, April 23, 2026: OpenAI GPT-5.5 was released on April 23, 2026, as the company’s latest artificial intelligence model. The new version is described as more advanced and efficient, marking another step toward OpenAI’s goal of building a unified AI super app.
San Francisco, April 23, 2026 — OpenAI announced the launch of GPT-5.5, calling it its smartest and most intuitive model so far. The model introduces improvements in coding, research, data analysis, and general knowledge work.
According to OpenAI co-founder and president Greg Brockman, the release represents progress toward more agentic computing. He said the model is a faster, sharper thinker that uses fewer tokens while delivering stronger performance compared to earlier versions.
The company said GPT-5.5 performs better across several benchmarks when compared with its previous models and competing systems such as Gemini 3.1 Pro and Claude Opus 4.5.
OpenAI also highlighted improvements in areas such as scientific research and enterprise applications. The model is designed to handle complex, multi-step tasks, including software development workflows and technical problem-solving.
Chief research officer Mark Chen said GPT-5.5 shows meaningful gains on scientific and technical research workflows and could support areas like drug discovery.
The release also ties into OpenAI’s broader plan to develop a super app. The concept, discussed by CEO Sam Altman and Greg Brockman, aims to combine tools like ChatGPT, Codex, and an AI browser into a single platform for both consumers and enterprise users.
Competition in this space is increasing, with Elon Musk also expressing plans to transform X into a similar all-in-one platform.
OpenAI said GPT-5.5 is being rolled out to Plus, Pro, Business, and Enterprise users within ChatGPT. A more advanced version, GPT-5.5 Pro, will be available to higher-tier users.
The company has released multiple models in recent months and indicated that rapid updates will continue. Chief scientist Jakub Pachocki said improvements in AI development are expected to accelerate further in the near future.
OpenAI stated that GPT-5.5 includes enhanced safety measures and has been tested with external partners before release. The company said it will continue refining safeguards as the model is deployed at scale.
The rollout of GPT-5.5 marks another step in OpenAI’s strategy to expand AI capabilities across industries while working toward a more integrated computing platform.
