Adventures in Agentic AI Simulation Land

2025-03-11

(Or, How We Learned to Stop Worrying and Love the Cloud)

Have you ever wondered how a cloud-based, multi-agent AI service handles a flurry of incoming user requests without spontaneously combusting? Well, wonder no more! In this blog post, we’ll embark on a fun, light-hearted journey through a simulation that tests just how gracefully an AI agentic system (think: a set of AI agents working together) scales, splits, and handles all sorts of query traffic. We’ll talk about our framework, assumptions, code, and results—complete with a snazzy chart to show off our data.
