’s AI unit recently concluded the training of “a new family of AI model” that are currently in development under the “MAI” codename. Internally, the team is hopeful that these in-house models perform nearly as well as the top AI models from the likes of OpenAI and Anthropic.

Under the leadership of its AI chief, Mustafa Suleyman,

These two new AI models are already available to developers via

is also exploring third-party options such as DeepSeek, xAI, and Meta. DeepSeek recently made waves by offering a high performance benchmark at a dramatically lower development cost. It has already been adopted by numerous companies and recently

Today, we are advancing our AI ambitions with the release of DeepSeek R1 7B & 14B distilled models for Copilot+ PCs via Azure AI Foundry. This is the next step on our journey to continue to make Windows the platform for AI, seamlessly integrating intelligence from the cloud to…

against OpenAI products such as GPT-o1 as well as ******** upstarts such as DeepSeek, both of which offer reasoning capabilities.

Apparently, the work on an in-house reasoning model has been expedited due to strained relationships between

and OpenAI teams over technology sharing. According to The Information, Suleyman and OpenAI have been at odds over the latter’s lack of transparency regarding the intricate workings of its AI models such as GPT-o1.

Reasoning models are deemed to be the next frontier for AI development, as they offer a more nuanced understanding of queries, logical deduction, and better problem solving capabilities.
