Microsoft AI launches its first in-house models

Microsoft's AI division has announced the launch of its first in-house AI models, MAI-Voice-1 and MAI-1-preview. MAI-Voice-1 is a speech model that can generate a minute's worth of audio in under one second on a single GPU, and is already being used to power features like Copilot Daily, which has an AI host recite the day's top news stories. MAI-1-preview, on the other hand, is a large language model trained on 15,000 Nvidia H100 GPUs, and is designed to follow instructions and provide helpful responses to everyday queries. Microsoft plans to integrate MAI-1-preview into its Copilot AI assistant, which currently relies on OpenAI's models. The company has also started publicly testing the MAI-1-preview model on the AI benchmarking platform LMArena. Microsoft's AI chief, Mustafa Suleyman, has stated that the company's internal AI models are focused on consumer use cases rather than enterprise applications.
