Release Summary
Microsoft's private reinforcement-learning tuning service for MAI models on customer workflows, data, and M365 context. Models train in your environment with self-serve, developer, or co-create paths; early adopters report up to 10x efficiency versus general frontier models (e.g. Excel-tuned MAI vs GPT 5.4). Includes a Mayo Clinic healthcare co-development partnership.
