Microsoft debuts first in house AI models for Copilot platform
- Microsoft debuts its first homegrown AI models, MAI-Voice-1 and MAI-1-Preview.
- MAI-Voice-1 powers narrated news, explainers, and offers ultra-fast audio generation.
- MAI-1-Preview handles text based queries and showcases Microsoft’s future AI roadmap.
Microsoft has unveiled its first internally developed AI models MAI-Voice-1 and MAI-1-Preview, marking a major step in the company’s push to build proprietary AI tools for its growing Copilot platform.
The highlight is MAI-Voice-1, a speech generation model designed for speed and efficiency. It can generate one minute of audio in under a second using just one GPU. Microsoft is already using this model in products like Copilot Daily, which delivers narrated news briefings, and podcast style explainers that simplify complex topics.
Users can also test MAI-Voice-1 through Copilot Labs, where they can generate speech using various voices and speaking styles, opening creative possibilities for personalized audio content.
Alongside it, Microsoft introduced MAI-1-Preview, a powerful text based model trained on 15,000 Nvidia H100 GPUs. It’s built to follow instructions and handle everyday questions. The model is currently being tested on LMArena, a benchmarking platform, and is expected to be integrated into select Copilot features soon.
Microsoft’s AI chief, Mustafa Suleyman emphasized a consumer first approach. Unlike enterprise focused models, Microsoft’s AI is designed to serve as a true digital companion, informed by real consumer behavior and advertising data.
