Anders Larson, FSA,MAAA and Shea Parkes, FSA, MAAA provide a clear, approachable look at how modern AI systems really think, act, and respond. They dive into the hidden machinery behind today's GenAI applications – exploring how agent frameworks guide LLMs through structured, choose‑your‑own‑adventure–style decision loops. Using practical examples from Microsoft Copilot and actuarial workflows, they break down how middleware, tool calls, and general context transform raw models into useful business assistants.
