## Microsoft claims model beats OpenAI
Mustafa Suleyman, CEO of Microsoft AI, told employees Thursday that the company's new model outperforms OpenAI's offering that powers GPT-5.6.
## Using a quarter of the computing power
Suleyman said Microsoft used one-quarter of the compute that OpenAI used to train their model, potentially saving significant money on expensive computing resources.

> We now have a stronger pre-trained base model than the model that currently powers GPT 5.6 Sol. And in fact, we used one-quarter of the compute that OpenAI used to train their model.
## The new model is MAI-Base-2
Microsoft announced MAI-Base-2 on Thursday. Suleyman said the model performed better than OpenAI models on tests measuring how well AI understands and predicts patterns in information.
## Also more efficient than DeepSeek
Suleyman said Microsoft's model used twelve times less computation than DeepSeek's offering for compute efficiency, comparing it to DeepSeek-V4-Pro-Base.
## Microsoft distances itself from OpenAI
The comments signal Microsoft's effort to branch out from OpenAI despite billions in investment and a major partnership. Microsoft declined to comment and OpenAI did not respond.
## Key takeaway

Microsoft AI CEO Mustafa Suleyman told employees the company's new MAI-Base-2 model beats OpenAI's GPT-5.6 using one-quarter of the computing power, signalling Microsoft's push to reduce dependence on its major partner.
