What actually turns a chatbot into an AI agent? The “harness” around the AI model (the large language model, or LLM).

In this video I break down what a harness is: a large language model at the core, plus memory, tools, and the engineering systems that make it all work at scale.

One piece I didn't get to in the video: the thing that ties it all together is the loop. An agent doesn't just answer once and stop. It runs in a cycle; the model decides what to do, takes an action (call a tool, check memory), looks at what came back, and picks its next move. Again and again, working several steps toward a goal. The loop is foundational to what makes agents work.

A key part of that loop is knowing when to stop - recognizing the task is actually done instead of spinning forever or quitting too early. "Knowing when to terminate" is its own small piece of engineering.

Model = the brain. Harness = everything that lets it actually get work done.

Questions? Please leave them below, and follow along - more on agents (and open-source models like DeepSeek) coming.

Jesus Christ is our ultimate exemplar, “who for the joy that was set before him endured the cross” (Hebrews 12:2).

He lives! He is our Advocate with the Father and our Redeemer.

Without His Resurrection, death would be the end. Our Savior’s Atonement made eternal life a possibility and immortality a reality for all. #BecauseofHim

@IAmPascio Good tools, but most of them are free when just starting... then you gotta pay. Fair enough though. Thank you @IAmPascio .

@heyeaslo I'd consider WordPress for almost all those categories.
