In a notable event at the Microsoft Build 2025 developer conference, Elon Musk , CEO of xAI and Tesla, joined Microsoft CEO Satya Nadella to announce the integration of xAI’s flagship Grok 3 AI models on Microsoft Azure. This announcement marks a significant step in the evolving artificial intelligence landscape, bringing together two major technology powerhouses. The Grok models will be accessible for free throughout June on the Azure AI Foundry platform, which also features AI offerings from industry leaders such as OpenAI, Meta, and Hugging Face.
This collaboration highlights not only technological innovation but also the historical ties between Musk and Microsoft, recalling Musk’s early programming days as a Microsoft intern. This detailed report covers all aspects of the announcement, the technology behind Grok, the significance of this partnership, and the future prospects of AI development on Azure.
Elon Musk’s early connection with Microsoft
During the Build conference, Satya Nadella took a moment to reflect on Elon Musk’s early career. Nadella reminded the audience of Musk’s internship at Microsoft, stating, “I know you started off as an intern at Microsoft. You were a PC gamer then—and still are.” Musk responded warmly, sharing memories of his beginnings before Windows with MS-DOS on the earliest IBM PCs. He highlighted the technological limitations of that era, recalling how memory upgrades from 128k to 256k were significant milestones. Musk also described programming video games in DOS and later working with Windows 3.1, emphasizing his foundational experience in software development which shaped his future ventures.
xAI’s Grok 3 AI models now available on Microsoft Azure
The core of the announcement focused on the launch of Grok 3, xAI’s advanced family of AI models, now integrated with Microsoft Azure’s cloud infrastructure. Nadella introduced Grok as “a family of models that are both responsive and capable of reasoning,” expressing enthusiasm about its deployment on Azure AI Foundry, Microsoft’s AI platform that offers scalable, managed AI services to developers and enterprises worldwide.
The availability of Grok 3 and Grok 3 Mini on Azure aims to broaden access to cutting-edge AI capabilities. Microsoft will provide these models with service-level agreements consistent with their other AI offerings, and billing will be streamlined through Microsoft’s standard Azure framework. This ensures ease of integration for enterprises already operating within the Azure ecosystem.
Technical insights into Grok 3.5
Elon Musk elaborated on the forthcoming Grok 3.5 model during the conversation. He described it as an AI designed to “reason from first principles,” a philosophical approach emphasizing fundamental truths and axioms as the basis for knowledge and problem-solving. Musk explained that the model’s architecture is grounded in fundamental physics, allowing it to apply these principles across different reasoning domains with an aim to minimize error and approach accurate understanding.
This emphasis on physics-based reasoning sets Grok apart from many AI models that rely primarily on pattern recognition and statistical inference. By integrating first-principles reasoning, Grok 3.5 aspires to provide more reliable, consistent outputs, potentially enhancing applications across diverse fields such as autonomous vehicles, space exploration, and customer service.
Significance of the Microsoft-xAI collaboration
The integration of Grok into Azure represents a strategic alliance that leverages Microsoft’s extensive cloud infrastructure and xAI’s innovative AI research. This collaboration extends the reach of Musk’s xAI beyond standalone systems, embedding it within one of the largest and most trusted cloud platforms globally.
Azure AI Foundry already hosts models from major AI developers like OpenAI, Meta, and Hugging Face, making it a hub for AI innovation and adoption. Grok’s addition to this ecosystem reflects Microsoft’s commitment to providing diverse AI options to developers and enterprises.
The partnership also comes amid industry discussions regarding the influence of large tech firms on AI development. Musk’s previous criticisms of Microsoft’s role in OpenAI’s operations add a layer of complexity to this collaboration, underscoring the nuanced relationships shaping the AI industry.
Free access to Grok AI on Azure available this June
Microsoft announced that Grok models will be available free of charge throughout June, allowing developers, researchers, and businesses to explore and experiment with xAI’s technology. This limited free access serves to increase adoption and foster community feedback, critical for refining AI capabilities and expanding real-world applications.
Post-June, Grok’s services will continue under Microsoft’s commercial terms, integrated fully within the Azure billing and support system. This seamless integration facilitates enterprise-grade deployment, enabling customers to incorporate Grok-powered AI into their existing workflows with minimal friction.
Future outlook and industry impact
The collaboration between Microsoft and xAI marks a pivotal moment in AI development, demonstrating the growing importance of cloud platforms as hubs for AI innovation and distribution. By combining xAI’s first-principles reasoning models with Microsoft’s global cloud reach, this partnership is poised to accelerate the deployment of advanced AI solutions across industries.
As AI technologies continue to evolve rapidly, partnerships like this provide essential infrastructure and support for scalable AI applications in sectors such as automotive, aerospace, healthcare, and customer experience. The free access period in June offers the broader tech community an opportunity to assess Grok’s capabilities and potential impact.
