Microsoft launches own AI models to take on OpenAI, Google

Tech giant Microsoft has released its first in-house artificial intelligence (AI) models under the Microsoft AI (MAI) team. The two models are:

• MAI-1-preview: This is a large language model (LLM) designed to follow instructions and answer queries.
• MAI-Voice-1: This is an expressive speech generation model.

Significance


The Satya Nadella-led company has been pushing to reduce its reliance on OpenAI, especially since tensions between them in late 2023 which involved leadership changes and several senior departures. The MAI initiative is a move towards this aim as both companies pursue their own ambitions in the increasingly competitive arena. By taking the AI reins in its own hands, Microsoft gains more control over how its technology works and how much it costs.

Microsoft has already deployed these models in its Copilot tools, including Copilot Daily and Copilot Labs. The new models are also designed to work better with Microsoft’s products such as Windows, Office, and Teams.

How do these stand out?

• MAI-1-preview uses a “mixture-of-experts” design, which it claims makes the models more efficient and scalable than traditional models.
• MAI-Voice-1 can generate a minute of audio in less than a second and supports multiple speakers and voice styles.

Microsoft’s models will mainly compete with OpenAI’s GPT-4 and GPT-5, Google’s Gemini, Anthropic’s Claude and Meta’s LLaMA. Each of these companies has a headstart in building and distributing its AI systems to consumers. Microsoft is counting on its vertical integration with everyday tools and its strong enterprise reputation to race ahead.

The company also plans to build more specialised models and continue using a mix of its own, OpenAI’s, and open-source models.

This comes weeks after OpenAI officially launched GPT-5, terming it their most advanced model yet. The much-anticipated model features major upgrades in reasoning, coding, writing, health, and multimodal capabilities.

Feedback from users, however, has been mixed. The model's capabilities were impressive said some, but the rollout itself faced issues. Many users complained about rate limits, touch-mode glitches, and the removal of older models, which the company had to reverse later.
