Microsoft Foundry will make OpenAI’s latest large language model, GPT-5.5, available to enterprise customers starting next month. The model will run on Microsoft Azure, giving companies direct access to what OpenAI describes as its most advanced general-purpose AI system to date. Enterprise teams focused on building production-grade AI agents will be the first to integrate the new model into their workflows.
The move follows Microsoft’s recent expansion of its AI Foundry service, a managed platform designed to help businesses deploy and scale AI models without managing underlying infrastructure. GPT-5.5 will be offered through this service, simplifying deployment for organizations that need high-performance AI without the complexity of self-hosting. Microsoft has not disclosed pricing details but confirmed that existing Azure customers will have priority access.
OpenAI’s GPT-5.5 introduces improvements in reasoning, coding, and long-context understanding compared to its predecessor. Early benchmarks suggest it outperforms GPT-4 in tasks requiring multi-step problem solving and technical accuracy. Microsoft’s announcement emphasized the model’s readiness for enterprise use, citing security certifications and compliance with industry standards.
Industry analysts see this as a significant step toward making frontier AI more accessible to businesses. The integration with Microsoft Foundry means companies can deploy GPT-5.5 alongside other AI tools in a unified environment. Microsoft’s blog post highlighted use cases in customer service automation, internal knowledge management, and software development assistance.
No timeline for broader availability was provided, though Microsoft indicated it would expand access based on demand. The company also confirmed that GPT-5.5 will be available in both cloud and on-premises configurations for customers with strict data residency requirements.
