[AINews] Microsoft Build: MAI-Thinking-1 and MAI Family models

Microsoft launched seven new MAI-Thinking-1 and MAI Family models at Build. The models are all from-scratch pretrainings, built under the Microsoft-Inflection partnership that began two years ago. Each model is designed for domain-specific fine-tuning, supporting practical applications in real-world scenarios. The MAI Family includes MAI-Thinking-1, a model focused on reasoning and task execution. These models represent a tier 2 neolab effort, distinct from frontier labs that have discontinued fine-tuning. The release strengthens Microsoft's position in applied AI for developers and enterprises.
