Microsoft has announced a project it has been "refining in secret for years;" Its own custom silicon in the form of two new server chips. The company unveiled the fruits of its labor at Microsoft Ignite, showing off the Azure Maia AI Accelerator and the Azure Cobalt CPU. The latter of which, at least, the company is happy to admit is ARM-based, which can still feel unthinkable to eyes so used to Microsoft and Intel's hand-in-glove dominance of the computing market. The company turned to OpenAI to receive feedback on Azure Maia and to use the company's models for testing. OpenAI CEO Sam Altman said the updated Microsoft's Azure will also provide the opportunity for training improved models and making them more affordable for customers.
