Writing on world models, agents, causal inference, and the future of operational decision-making.
Task agents act. Decision agents have to reason first, and that needs a different foundation.
Your supply chain isn't a list of vendors. It's a living graph of relationships, flows, and dependencies. Here's why that distinction matters when things go wrong.
Before AI agents can optimize your supply chain, they need something to reason about. That something is a context graph they can traverse, query, and simulate against.
A guided, ground-up path through causality, the discipline behind every world model. Start with why correlation was never enough, and build toward models that reason about cause and effect.
A world model carries a causal representation of a system and evolves it forward under the actions you take. Applied to an enterprise, that means state (the live configuration of the business), transitions (causal functions describing how actions change it), and an entity graph carrying the constraints the business obeys. The result supports three kinds of reasoning descriptive analytics can't: look forward, look sideways, and look backward to act forward.
Revenue tools score deals and transcribe calls. None of them can answer the question every CRO carries into the quarter: what happens if we act? A world model of the revenue engine lets a decision agent simulate a pricing change, a territory redesign, or an ICP shift before anyone commits, with every recommendation traced to a cause and checked against business constraints.
Planning tools optimise a fixed model of the operation, and dashboards report problems after they've happened. Neither can answer the question that defines operations work: what happens if we act? A world model of the operation lets a decision agent simulate a supplier switch, a safety-stock change, or a re-route before committing, surface disruptions while they're still in the future, and replan only the part of the network that's affected.
Every AI agent runs on a loop (a cycle of look, decide, act, look again) repeated until a goal is met. The loop is what separates an agent from a chatbot, and it's the double-edge sword of both the agent's power and weakness: it acts first and finds out afterwards. A world model changes the loop at its core. It inserts a step that has never been there (<em>simulate the action before committing to it</em>), and it wraps a second, slower loop around the whole thing that learns from what really happened. This piece explains loops from first principles, then shows precisely what changes when a world model is underneath.
