At Microsoft's 50th anniversary celebration in Redmond, current and former CEOs gathered to reflect on the tech giant’s evolution. Among the voices on stage, AI CEO Mustafa Suleyman drew attention for his focus on a lesser-known but crucial performance metric for Copilot.
Instead of just active user numbers or time spent, Suleyman emphasizes SSR — the "Rate of Successful Sessions." He defines it as a more meaningful gauge of how effectively Copilot assists users during interactions.
“I really, really focus the team on SSR,” he shared, noting that AI itself now helps analyze sentiment and optimize this metric through anonymized user logs.
Microsoft has rolled out major updates: a friendlier voice assistant, web page analysis, and personalized podcast generation. More updates, including a custom visual style for each user and conversation, are in the pipeline.
Though Suleyman declined to disclose exact numbers, he said SSR has improved significantly in recent months.
Suleyman’s SSR-first approach could redefine how AI tools are measured in terms of real impact. As Copilot continues to evolve, user satisfaction—not just engagement—might become the industry standard.
