Capacity Efficiency at Meta: How Unified AI Agents Optimize Performance at Hyperscale

Meta's Capacity Efficiency Program utilizes a unified AI agent platform to automate optimization of performance issues in their infrastructure, freeing up engineers' time to innovate on new products. The platform encodes domain expertise of senior engineers into reusable skills, reducing power consumption by hundreds of megawatts and compressing hours-long manual regression investigations into minutes. By combining standardized tool interfaces with encoded domain expertise, AI agents can automate both finding and fixing performance issues, enabling the program to scale without proportionally increasing headcount.
