Open AI GPT-5.5 is also available for Azure AI creators & developers through Microsoft Foundry.

OpenAI’s GPT-5.5 is generally available in Microsoft Foundry, bringing OpenAI’s latest frontier model to Azure and the enterprise teams building agents for real production work.

GPT-5.5 continues a clear progression in the GPT-5 series. GPT-5 brought unified reasoning and speed into a single system. GPT-5.4 brought stronger multi-step reasoning and early agentic capabilities for enterprise use. GPT-5.5 advances this arc with deeper long-context reasoning, more reliable agentic execution, improved computer-use accuracy, and greater token efficiency—designed for sustained, high-stakes professional workflows.

Powerful models alone aren’t enough to operationalize agentic AI at scale. Microsoft Foundry provides the platform layer that turns frontier models into usable, governable systems that enable enterprises to apply security policy and management at the platform level. Foundry is a unified, interoperable environment to build, optimize, and deploy AI applications and agents with confidence. Customers benefit from broad model choice, open and flexible agent frameworks, native integration with enterprise systems and productivity tools, and enterprise-grade security, compliance, and governance. When new models like GPT-5.5 become available, Foundry makes it easy to evaluate, productionize, and scale them without friction.
