Microsoft launches Microsoft AI, hires Mustafa Suleyman

Microsoft has created a new organization, Microsoft AI, to accelerate the development of its public-facing artificial intelligence products. The division will be led by Mustafa Suleyman, the co-founder of DeepMind and Inflection AI, with Karen Simonyan, also a co-founder of Inflection, serving as chief scientist.

The move announced Tuesday is no conventional acquisition. Microsoft has hired Suleyman, Simonyan and several key members of Inflection, while the company itself will continue to operate independently and retain its Pi product. The two companies have also signed a commercial agreement allowing Microsoft to use Inflection’s models.

A new leader for consumer AI

Suleyman will report directly to Microsoft CEO Satya Nadella. His mission will be to lead the company’s consumer AI research and products, including Microsoft Copilot, Bing and Edge.

The assignment goes beyond adding automated features to familiar software. Microsoft is trying to turn Copilot into an assistance layer spanning its search engine, browser, Windows and productivity apps: an interface that can answer questions, summarize information, generate content and help users complete tasks through natural language.

The company already has a strategic partnership with OpenAI, the creator of ChatGPT, and has integrated that company’s models across much of its product lineup. Suleyman’s arrival, however, creates an in-house team specifically focused on defining the end-user experience. Microsoft is seeking to control not only AI infrastructure and distribution, but also the design of the products that millions of people will use every day.

From DeepMind to Inflection

Mustafa Suleyman was one of DeepMind’s founders in 2010, alongside Demis Hassabis and Shane Legg. The British company became one of the decade’s most influential labs, particularly after Google acquired it in 2014 and following the advances made by AlphaGo, the system that defeated champion Lee Sedol at the game of Go.

Suleyman left DeepMind in 2019 and founded Inflection AI in 2022 with Karén Simonyan and Reid Hoffman, the co-founder of LinkedIn. Inflection launched Pi, a conversational assistant that set itself apart from ChatGPT by prioritizing a personal, supportive tone over productivity or information retrieval.

The company also developed Inflection-1 and Inflection-2, large language models. These systems are networks trained on vast amounts of text to predict and generate language—a technique that underpins today’s conversational assistants.

A deal that transforms Inflection

Inflection will continue to operate, but it will have to reorganize after the departure of much of its technical and executive team. Reid Hoffman and DeepMind co-founder Mustafa Suleyman had placed the company among the best-funded startups of the new generation of large language models: Inflection raised $1.3 billion in 2023 with backing from Microsoft, Nvidia and other investors.

The company’s next phase will focus more heavily on offering its technology to businesses. For Microsoft, the agreement provides talent, technical expertise and access to models without formally taking over the startup in full.

That structure could have consequences in an industry where major companies are competing for a limited pool of specialized researchers and engineers. Hiring entire teams and licensing their technology makes it possible to integrate capabilities quickly, while leaving open questions about the actual continuity of companies that lose their founders and a substantial portion of their staff.

More competition inside and outside Microsoft

The decision also strengthens Microsoft’s position against Google, Meta, Amazon and the startups developing their own models. The race is no longer just about training more capable systems; it depends on who can turn them into reliable, accessible and useful tools for people and businesses.

Microsoft starts with an unusual advantage. It can distribute Copilot through Windows, Office, Bing, Azure and GitHub, while also benefiting from its partnership with OpenAI. Suleyman brings experience in research, product development and public debate over the risks posed by advanced systems.

The challenge will be coordinating the new organization with Microsoft’s existing teams and with OpenAI, whose agreement with the company remains central to its strategy. The creation of Microsoft AI indicates that Redmond wants to reduce its reliance on a single source of innovation and build its own identity for its artificial intelligence assistants.
