Microsoft, one of OpenAI’s biggest backers, is quietly working to depend less on the AI startup it once bet billions on. The tech giant’s AI chief, Mustafa Suleyman, is leading efforts to build homegrown AI models that could replace OpenAI’s tech in products like Copilot. Here is why and what it means for the future of AI.
Why Microsoft Wants Out
Microsoft has invested over $13 billion in OpenAI since 2019. But relying on another company’s tech comes with risks. Last year’s chaos at OpenAI, when CEO Sam Altman was briefly fired, showed Microsoft how shaky partnerships can be. Now, Microsoft wants control.
- High Costs
Running OpenAI’s models (like GPT-4) on Microsoft’s Azure cloud is expensive. Building cheaper in-house tools could save money.
- Strategic Independence
Microsoft wants its own AI brainpower. Suleyman, who co-founded Google’s DeepMind, was hired in 2024 to lead this charge.
- Fear of Falling Behind
OpenAI keeps innovating, but Microsoft doesn’t want to play second fiddle forever.
The Rocky Road Ahead
Breaking up won’t be easy. OpenAI’s tech powers Microsoft’s Copilot, Bing AI search, and Office 365 tools. A 2030 contract gives Microsoft exclusive rights to OpenAI’s models, but Suleyman’s team is already testing replacements from companies like Meta and Elon Musk’s xAI.
Last fall, tensions flared during a video call where Microsoft pushed OpenAI to explain how its latest model, “o1,” worked. Insiders say Suleyman’s team wants technical secrets to build similar tools.
Small Wins, Big Challenges
Microsoft has started swapping OpenAI models in Copilot with its own, like Phi-4. But progress is slow. Technical issues and team conflicts seem to be responsible for reported delays according to known accounts.
According to The Information, the complete replacement of GPT-4 in Copilot demands starting from raw features to reconstruct them manually because it requires complex work. OpenAI’s models function extensively within Microsoft products. Untangling them could take years.
What is Next for Microsoft and OpenAI?
If Microsoft succeeds, it could slash costs and lead the AI race on its own terms. But OpenAI isn’t standing still. Its models still set industry standards, and the partnership brings Microsoft revenue.
The tech world is watching closely. Can Microsoft truly go solo, or will it stay tied to OpenAI? For now, Suleyman’s team is taking it one AI model at a time.
