Microsoft aims to join big four AI model developers

Microsoft used its annual Build developer conference to unveil its own reasoning model, AI agents and cybersecurity tools, signaling a shift toward an AI strategy centered on in-house models. It introduced its first reasoning model, MAI-Thinking-1, and six models for images, voice, transcription and coding. Microsoft AI chief Mustafa Suleyman said the goal is to prove Microsoft can be among the world’s top four research labs.
