GPT-5.5 is Now Available in Microsoft Foundry for Enterprise Use

After weeks of leaks and rumors, OpenAI finally released GPT-5.5 yesterday. The company calls the new model as its smartest and the most intuitive to use model to date. Not to forget, there is a “Pro” model called GPT-5.5 Pro.

As Microsoft does everytime when a new model lands, it is bringing GPT-5.5 to Microsoft foundry for enterprise use. Starting today, GPT-5.5 is now available in Microsoft Foundry. Speaking of core features, the latest model is definutely an improvement over GPT-5.4 on paper.

The details shared by OpenAI in the announcement post indicates that GPT-5.5 advances with deeper long-context reasoning, more refined agentic execution, improved computer-use accuracy, and greater token efficiency. All of that makes it suitable for high-stakes professional workflows.

One of the standout points is that GPT-5.5 beats Anthropic’s latest Claude Opus 4.7 on almost every benchmark that the company tested it on. Worth noting that Claude Opus 4.7 is also available in Microsoft Foundry.

Coming back to GPT-5.5, it’s handy in reasoning and professional workloads, especially in document-heavy and tool-using environments where models need to stay consistent across longer workflows. GPT-5.5 also shows strong performance in tasks that mirror real office environments like data analysis, reporting, and workflow automation.

OpenAI also says that GPT-5.5 matches GPT-5.4‘s latency in real-world use while offering higher-quality outputs. The model also shows stronger efficiency in coding workflows. As of the pricing, OpenAI will charge $5 per 1 million input tokens and $30 per 1 million output tokens, with a 1 million context window.
