Modern cloud systems are becoming increasingly complex to manage with the rise of LLMs. AI agents constantly create and modify workloads. Teams are losing visibility and control over their cloud operations. At PRESAGE, we develop world-modelโ€“based AI that learns how an infrastructure actually works, how components interact, how load propagates, and how incidents emerge. This enables prediction, simulation, and proactive decision-making, not just monitoring.
