AI chief Mustafa Suleyman shared insights on the company's approach to measuring the success of its AI assistant, Copilot

At Microsoft's 50th anniversary celebration, AI chief Mustafa Suleyman shared insights on the company's approach to measuring the success of its AI assistant, Copilot. The primary metric he focuses on is the "rate of successful sessions" (SSR), which evaluates the sentiment and effectiveness of user interactions with Copilot. This represents a shift from traditional metrics like time spent on a product.

Microsoft uses AI to analyze anonymized chat logs to assess sentiment and improve SSR, which has seen significant improvement over the past four months. New Copilot features were introduced during the event, such as personalized podcasts and tools for complex research queries. Suleyman also hinted at customizable looks for Copilot, adding a touch of personalization to user interactions.
