Microsoft AI unveils MAI-Voice-1 and MAI-1-preview models

Investing.com -- Microsoft AI (MAI) has introduced two new in-house AI models as part of its mission to create AI that empowers everyone globally.

The company released MAI-Voice-1, a speech generation model that can create a full minute of audio in under a second on a single GPU. This model is already powering features in Copilot Daily and Podcasts, and is now available in Copilot Labs where users can test expressive speech and storytelling capabilities.

MAI also began public testing of MAI-1-preview on LMArena, a platform for community model evaluation. This foundation model was trained end-to-end on approximately 15,000 NVIDIA H100 GPUs and is designed to follow instructions and provide helpful responses to everyday queries.

The company plans to implement MAI-1-preview for certain text use cases within Copilot over the coming weeks to gather user feedback. The model is also being made available to trusted testers who can apply for API access.

Microsoft AI stated it will continue using models from its team, partners, and open-source innovations to power its products. The company mentioned its next-generation GB200 cluster is now operational as part of its computing infrastructure.
