Microsoft’s complex collaboration with OpenAI is taking on a new dimension. The company has announced its first self-developed artificial intelligence models: MAI-Voice-1 and MAI-1-preview.

Microsoft’s artificial intelligence division recently announced its first in-house developed models: MAI-Voice-1 and MAI-1-preview. The technology giant is known to be one of OpenAI’s biggest partners and supporters. However, the company’s introduction of its own models further complicates its relationship with OpenAI.

Microsoft has released its own models

MAI-Voice-1 can generate one minute of audio in less than a second on a single GPU. This model is already being used in features like Copilot Daily. The tool can read the day’s top news aloud to the user and explain topics in a podcast style. Additionally, this system, which anyone can try via Copilot Labs, offers the ability to personalize voice tone and speaking style settings.

On the other hand, the MAI-1-preview model was trained using approximately 15,000 Nvidia H100 GPUs. Microsoft is positioning this model specifically as an assistant that can provide meaningful and useful answers to everyday questions. While the company prepares to integrate this model into Copilot, it is also testing it on the AI benchmark platform called LMArena. Microsoft AI CEO, Mustafa Suleyman, had previously stated that the focus of their models is on the consumer experience, not enterprise. The advertising and user interaction data held by the company also facilitates the development of more powerful artificial intelligences. In the future, Microsoft aims to build an ecosystem of specialized models for different use cases.
