Microsoft to unveil new in-house AI models at Build conference

Microsoft shares rose on Thursday after reports indicated the company plans to introduce a new suite of proprietary artificial intelligence models at its annual Build developer conference scheduled for June 2 to June 3 in San Francisco. The announcements are expected to include a dedicated coding model aimed at strengthening GitHub Copilot’s position in an increasingly competitive market for AI-assisted programming tools.

The planned coding model is designed to enhance developer workflows and compete more directly with emerging rivals such as Cursor and Anthropic’s Claude Code system. The move reflects Microsoft’s broader strategy to reduce reliance on external partners and expand its internal AI capabilities across productivity and developer tools. Investors reacted positively to the reports, sending the company’s stock higher in early trading.

Microsoft has steadily expanded its portfolio of in-house models over the past year. In April, the company introduced MAI-Transcribe-1 for multilingual speech-to-text transcription, MAI-Voice-1 for customized audio generation, and MAI-Image-2 for image and video creation. These systems are available through Azure AI Foundry and represent a growing effort to build a full-stack AI ecosystem under Microsoft’s control.

Earlier developments included the rollout of MAI-Voice-1 and MAI-1-preview in 2025, marking Microsoft’s first internally trained foundation model. That model was developed using approximately 15,000 Nvidia H100 GPUs, underscoring the scale of infrastructure investment required to compete in advanced generative AI. Company leadership has repeatedly signaled ambitions to reach frontier-level performance across text, image, and audio models by 2027.

Microsoft AI chief Mustafa Suleyman has stated that the company aims to reach state-of-the-art performance across multiple modalities within the next two years. He has emphasized the need to push the boundaries of AI development as competition intensifies across the sector, particularly in enterprise and developer-focused applications.

The timing of the Build conference reflects a renewed focus on San Francisco as a central hub for developer engagement. The event will take place at the Fort Mason Center and will include both in-person and virtual programming. Key themes are expected to include AI agents, multimodal systems, and large-scale cloud infrastructure.

GitHub Copilot, one of Microsoft’s flagship AI products, faces increasing pressure from alternative coding tools that offer deeper integration with developer environments. Cursor, a modified version of Visual Studio Code, has gained traction among programmers seeking more flexible AI assistance, while Anthropic’s Claude models are also expanding their presence in software development tasks. In response, GitHub has already shifted its pricing model toward usage-based billing through AI credits, signaling a broader commercialization shift within the ecosystem.
