Microsoft Shows Off In-House Tech. Is the Stock a Buy?

Microsoft unveiled seven new in-house AI models at its Build developer conference, including its flagship MAI-Thinking-1 model that outperforms OpenAI's GPT-5 with 10x better cost efficiency. The company also introduced a new topological quantum chip (Majorana 2) with significantly improved stability. These developments aim to reduce Microsoft's dependence on OpenAI and lower AI infrastructure costs, positioning the company as both an AI creator and user.
