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

Microsoft unveiled seven new in-house AI models at its Build conference. Its flagship MAI-Thinking-1 model was built from scratch without distillation. Using McKinsey benchmarks, it outperformed OpenAI's GPT 5-5 with 10 times better cost efficiency. The company introduced models for coding, image, voice, and transcription. Microsoft can reduce costs by cutting payments to third-party AI firms like OpenAI.
