GoKawiilAt Microsoft’s annual Build conference on Tuesday, the company announced a slew of new or expanded AI initiatives, including a super app, in-house reasoning models, a cybersecurity tool, and OpenClaw-esque AI agents. All this news added up to a clear message: Microsoft is positioned to be one of the biggest players in AI, and it’s finally acting like it.
For years, Microsoft’s AI business leaned hard on its early and exclusive partnership with OpenAI. But the drama-filled marriage slowly devolved into a situationship, and the pair effectively separated in late April (though Microsoft is still OpenAI’s primary cloud partner — for now). This year’s Build had the vibe of a freshly single divorcée posting a thirst trap on Instagram. “It’s always fun to be at developer conferences in times of great change,” Microsoft CEO Satya Nadella said onstage Tuesday, adding that events like this are about “coming to grips with the new opportunity.”
AI chief Mustafa Suleyman, in an interview with The Verge, put it even more bluntly.
“The goal is to prove that we can become one of the top four labs in the world,” Suleyman said. “There’s three labs that matter, Google DeepMind, OpenAI, and Anthropic. We are not one of them at the moment, and that’s always been my intention. It’s why I came here. I want to build the very best frontier models in the world, fully multimodal, and in order to do that, we have to prove that we can do everything that we need to from the ground up, and we’re not just going to take from others.”
One of Microsoft’s first steps at Build was indeed to play catch-up on AI models. Suleyman unveiled MAI-Thinking-1, the company’s first reasoning model, along with six other new models focused on image, voice, transcription, and coding. Microsoft said the medium-size MAI-Thinking-1 model, which will likely be marketed to primarily enterprise clients, is “built from scratch for serious math, coding, and real-world enterprise deployment.” Microsoft is years behind both OpenAI and Anthropic here; OpenAI began releasing reasoning models in the fall of 2024. But Suleyman emphasized its performance on benchmarks like coding and its price point, saying it was cheaper than OpenAI equivalents on some tasks — a big deal in the age of the AI money squeeze, which has inspired a lot of complaints with customers.
While Microsoft has had years to glean insights from OpenAI, Suleyman made sure to mention that its development did not involve any distillation, meaning that it wasn’t trained using a different company’s AI model. If MAI-Thinking-1 is good, Microsoft clearly doesn’t want people thinking it’s due to the influence of OpenAI.
Suleyman told The Verge that for Microsoft, “the pivotal moment was renegotiating our contract with OpenAI. That meant that we were allowed to train models at a larger scale and explicitly pursue superintelligence entirely with our own IP, with our own data, no distillation, training from scratch.”
Nadella also highlighted Microsoft’s recently launched AI cybersecurity tool MDASH, which he said brings together 100 AI agents to find exploitable bugs “better than any single model.” It was clearly a dig at Claude Mythos Preview, which Anthropic introduced in April to much fear and fanfare — and expanded access to just before Build. OpenAI has its own cybersecurity-focused system as well, and all three companies will likely use their offerings to jockey for position in the government and enterprise markets they desperately need to court.
Microsoft is in a more complex situation with AI agents. The popular open-source platform OpenClaw demonstrated a potential path forward for AI agents, and after OpenAI quickly hired its creator, Peter Steinberger, Microsoft (among other companies) is trying to catch up. One of its key strategies is making OpenClaw work well with Windows. At Build, Nadella said he was very committed to OpenClaw support, and Microsoft employees chatted with developers in the audience about how they were using it.
Steinberger himself made a surprise appearance to great audience reaction, taking the stage to boast about how OpenClaw had bolstered its security and earned user trust. “What I kept hearing was, ‘Peter, I love my Claw, but can I use it at work?’” Steinberger said. “You can totally run OpenClaw inside your company now, and we even made the harness itself a plug-in.” Steinberger said that whether someone trusts Copilot, Codex, or another company’s coding platform, users can now run OpenClaw on top of that via Windows.
