Microsoft has been a major player in the artificial intelligence boom, providing critical cloud infrastructure and services alongside multibillion-dollar equity investments in companies like OpenAI and Anthropic. The company is now intensifying its efforts to compete by developing its own proprietary models.
Microsoft's New AI Development Tools
On Tuesday, at the Build developer conference in San Francisco, Microsoft announced the launch of its first AI programming model, MAI-Code-1-Flash. This model can take a user's text description and directly output the source code for applications and websites. The AI programming market has grown rapidly in recent years, with developers and non-technical users employing text-based prompts to create complex software.
For Microsoft, offering its own models presents significant economic advantages as the cost of using industry-leading models continues to rise, and these savings can be passed on to developers. Microsoft can run these models on its own Azure cloud infrastructure, thereby avoiding fees paid to third parties like OpenAI. In May, Google also announced its Gemini 3.5 Flash model, which is capable of programming and other tasks and runs on Google's own data centers.
In addition to MAI-Code-1-Flash, Microsoft introduced the reasoning model MAI-Thinking-1, emphasizing that both products are highly efficient.
Focus on Cost Efficiency and Performance
Kyle Daigler, Microsoft's Head of Developer Marketing and GitHub Operations, wrote in a blog post that this medium-sized reasoning model is "designed for high capability and performance, and importantly, to run at a low token cost." Tokens are the fundamental units of data that models read, process, and generate, and their consumption determines the cost for developers.
As OpenAI and Anthropic continue to post record growth and advance toward public listings, Microsoft is seeking to play a role in more layers of the AI technology stack. Anthropic confidentially filed for an IPO on June 1, and OpenAI is also seeking to go public this year. Microsoft has invested $13 billion in OpenAI and $5 billion in Anthropic while also offering their models via the Azure platform.
Availability and Future Outlook
MAI-Thinking-1 is currently available for private preview through the Microsoft Foundry service, which is primarily used for integrating models into applications. Customers can express interest in testing the model before its wider release. Furthermore, customers can improve the accuracy of this reasoning model by incorporating their own data.

Microsoft CEO Satya Nadella stated on stage, "What you just saw was a pretty big shift. We believe now is the best time for every company to move from just consuming frontier models to participating fully in the frontier ecosystem."
Microsoft AI CEO Mustafa Suleyman revealed that after optimizing a model for the needs of consulting firm McKinsey, Microsoft's proprietary model successfully outperformed OpenAI's GPT-5 and achieved a tenfold improvement in cost efficiency.
Daigler wrote that the programming model is "super-efficient for reasoning" and is now available in the GitHub Copilot AI programming service and the Visual Studio Code text editor.
Also on Tuesday, Microsoft announced updates to cloud models in areas such as speech recognition, synthetic voice generation, and image generation, as well as small AI models that can run locally on Windows PCs.
