According to Satya Nadella (@satyanadella), at a recent developer event in Bengaluru, he demonstrated a new AI-powered application designed for deep research using multiple language models and structured decision frameworks. Nadella described the approach as a 'chain of debate,' highlighting its capability to synthesize diverse model outputs for more nuanced analysis. This method exemplifies the practical implementation of ensemble AI systems in research and enterprise decision-making, paving the way for advanced productivity tools like Copilot. The demo underscores the trend of integrating multi-model AI workflows to improve research efficiency and accuracy, signaling significant business opportunities for enterprises seeking competitive insights through AI-powered automation (Source: Satya Nadella, Twitter, Dec 11, 2025).
