Microsoft Build in San Francisco featured seven new in-house AI models, including a flagship reasoning model, a coding model, a transcription model, and a voice generation model. Microsoft also entered the AI agent space with Microsoft Scout, giving OpenAI direct access to Microsoft products and Windows management. The announcements signal a major push by Microsoft into competitive AI across multiple domains.

Summary

At Microsoft Build in San Francisco, Microsoft unveiled seven new AI models developed entirely in-house under the Microsoft AI brand. The centerpiece was a new thinking model positioned as their flagship reasoning model, designed for complex problem-solving tasks.

On the coding side, Microsoft introduced MAI Code One Flash, which was highlighted as being more accurate and more token-efficient than Claude Haiku 4.5, making it a competitive option for developers seeking cost-effective coding assistance. An ultraefficient flash variant was also announced, and despite its efficiency focus, it still ranks number two globally in image editing, narrowly behind GPT Image 2.

Microsoft also made strides in audio AI, announcing MAI Transcribe 1.5, which was claimed to be the best transcription model in the world at the time of the announcement. Complementing this, MAI Voice 2 was introduced as a speech generation model supporting 15 languages, with a live audio sample demonstrating its natural-sounding conversational output.

Finally, Microsoft entered the agentic AI space with the introduction of Microsoft Scout. This agent gives OpenAI direct integration into the broader Microsoft ecosystem, enabling it to operate across cloud, desktop, and web environments. It connects to Teams, Outlook, OneDrive, and SharePoint, with access to chats, emails, calendars, and contacts, and can directly manage Windows on behalf of users.

[0:00] I just got back from Microsoft Build out in San Francisco and there was a ton of announcements. They announced seven new models developed in-house at Microsoft AI. They built a new thinking model which is their new flagship reasoning model. They also introduced a new coding model MAI code one flash. It's more accurate and uses quite a bit less tokens than Claude Haiku 4.5. They also announced a new ultraefficient flash variant. and it is still ranked number [0:30] two in image editing, only very slightly being beat out by GPT image 2. They also announced a new transcription model, MAI transcribe 1.5, and it's currently the best transcription model in the world. And they announced MAI…
