Microsoft is working on a new generation of in-house artificial intelligence reasoning models designed to rival those from OpenAI, according to a report by The Information.
The company, which has been a major backer of OpenAI, is exploring options to reduce its dependence on external AI technology and may eventually offer these models to developers via an application programming interface.
The report indicates that Microsoft is testing models from xAI, Meta, and DeepSeek as potential replacements for the technology currently powering its Microsoft 365 Copilot. Reuters reported in December that Microsoft had been actively integrating both internal and third-party AI models into Copilot to diversify its technological foundation and lower costs, given that the service was originally built on OpenAI's GPT-4.
Microsoft’s AI division, led by Mustafa Suleyman, has reportedly completed training a family of models internally known as MAI. These models are said to perform nearly as well as leading models from OpenAI and Anthropic on standard benchmarks. In addition, Suleyman’s team is developing reasoning models that use chain-of-thought techniques—methods that generate answers through intermediate reasoning steps—to directly compete with similar models from OpenAI.
Suleyman’s team is already experimenting with replacing OpenAI’s models in Copilot with the newly developed MAI models, which are significantly larger than an earlier series known as Phi. Microsoft is considering a release of these models later this year in the form of an API, which would enable external developers to integrate the advanced AI reasoning capabilities into their own applications.
Neither Microsoft nor OpenAI immediately responded to requests for comment.
Microsoft has announced 6,000 job cuts, representing nearly 3% of its workforce, as part of a strategy to streamline operations and prioritize investments in artificial intelligence.
US Senators Elizabeth Warren and Ron Wyden are pressing Google and Microsoft for details on their AI partnerships, raising concerns that such deals may stifle competition, breach antitrust laws, and limit innovation in the fast-growing AI sector.
In a surprising move, Microsoft is reportedly reducing its data center footprint by canceling leases with several data center providers that together amount to a "couple hundred megawatts" of capacity - roughly equivalent to two full data centers.
In a major update to its AI assistant platform, Microsoft announced today that it will offer unlimited free access to two of Copilot’s advanced features—Voice and Think Deeper—powered by OpenAI’s o1 model.
