The speaker emphasizes that this approach shifts focus from perfecting prompts to creating a self-improving system, and demonstrates how it can save time and reduce manual oversight. ### Key Points - **The Big Idea** [00:02] — Loop Engineering uses one AI to build and another to judge, iterating until the work is good. This replaces manual prompting and quality control. - **Shift from Prompts to Loops** [00:29] — Experts now say the loop, not the prompt, is the main thing. The traditional prompt approach is outdated. - **How the Loop Works** [01:07] — Define 'good' in one sentence. One AI builds, another scores. If it passes, ship; if not, loop back. You set the number of rounds. - **Define the Goal Clearly** [01:20] — A fuzzy goal leads to fuzzy output. Be specific: e.g., 'Create a landing page with a clear headline, three benefits, and a sign-up button.' - **Builder and Judge Must Be Different** [02:11] — AI is a poor judge of its own work. Use a separate AI, ideally from a different family, to ensure honest evaluation. - **Example: Welcome Email** [02:51] — Builder writes a welcome email; judge checks if it's warm, clear, and includes next steps. Loops until criteria are met. - **AI Profit Boardroom Integration** [03:31] — The loop is pre-built in the Agent OS inside the AI Profit Boardroom, with coaching calls and tutorials. - **Real Run Results** [04:10] — Round 1 scores 4/100, round 2 jumps to 85, round 3 hits 100. The judge provides specific feedback for improvement. - **Cost Saving Strategy** [05:04] — Use a cheap, fast AI for building (which runs many times) and a strong, expensive AI for judging (which runs once per iteration). - **Three Loop Shapes** [05:55] — Simple loop (one builder, one judge), team of agents (multiple agents for complex tasks), and group chat (AI agents discuss and refine ideas). - **Hermes AI Agent** [07:02] — Hermes is a free, open AI agent with built-in timer, memory across sessions, and ability to build skills over time. It can monitor and fix landing pages autonomously. - **Caveats** [08:13] — A weak goal leads to weak output. Set a real bar and cap iterations (e.g., 20 rounds) to prevent infinite loops. ### Conclusion Loop Engineering automates quality control by having one AI build and another judge, freeing you from manual oversight. Set a clear goal, use different AI families, cap iterations, and let the loop run while you focus on other tasks. ## Transcript I'm going to show you exactly why. Here's the big idea. There's a new way to run AI where it checks its own work. You don't sit there all day, you don't type prompt after prompt. One AI builds the thing, a second AI grades it, and it keeps going until the work is good. People call this Loop Engineering, and it's real. Back in June 2026, some of the smartest people in AI all said the the main thing anymore. The loop is. Think about that. For 2 years, everyone said the trick was writing the perfect prompt. Now, the smart folks say the prompt. So, what does that mean for you? Let me make it dead simple. Right now, most people use AI like a kitchen where nobody tastes the food. It goes straight from the pan to the customer. Some of it who finds out? You do. You become the taster. You catch every mistake. You control. And the second you stop checking, junk goes out the door. This loop fixes that for good. Hey, if we haven't met already, I'm the digital avatar of Julian Goldie, CEO of SEO helping clients get more leads and customers, I'm here to help you get the latest AI updates. Julian Goldie reads every comment, so make sure you comment below. So, let me show you how it works. Plain and simple. You write down what good looks like in one sentence. One AI builds it. A different AI scores it. If it passes, great. If it fails, it loops back and tries again. You pick how many rounds it can run. You could say loop 20 times until it's done. Then you walk first step, because this is the one people rush. You have to tell the system what good actually means. Some folks call this the goal, or the definition of done. If your goal is fuzzy, every step after it is fuzzy, too. So, don't just say make me a page. Say make me a landing page for the AI Profit Boardroom with a clear headline, three benefits of joining our AI Automation Community, and a big sign-up button at the top. See the difference? The clearer your one sentence, the the the whole thing runs. Get that sentence right and half the work is already done. And here's the part that matters most. The builder and the judge are never the same AI, ever. Why? Because AI is a terrible judge of its own work. Same reason you can't proofread your own writing. You read what you meant to say, not what you actually wrote. There's real research on this. When an AI grades its own homework, it almost always says, "Looks every time. So, you need a fresh set of eyes, a second AI holding your goal in its hand, catches the obvious junk. Broken buttons, weak headlines, missing chunks, stuff you told it to do that it ignored, the stuff that eats your whole afternoon. And the researchers found one more rule worth knowing. The judge shouldn't just be a different agent. It should be a different family of AI, too. Because if the builder and the judge are too alike, the judge gets soft, same way a friend goes easy on a friend. A judge from a different family stays honest. Small detail, big difference in what you get back. Let me give you one quick example. Say you want more people in the AI Profit Boardroom. You tell the builder, "Write a welcome email for new members that points them to their first then the judge reads it and asks, "Is it warm? Is it clear? Does it tell them the next step?" If it misses, it loops. You get a clean email without writing a word "I'm not a tech person. This sounds like something only coders can do." Nope. If you can describe the job in one sentence, you can run this loop. That's code, you're writing one clear sentence and letting the machine do the rest. Now, before I show you a real run, quick pause. Because this is exactly the kind of thing we set up together inside the AI Profit Boardroom. We built the whole thing into something called the Agent OS. It's a ready-to-go system with the wired together. You grab the full zip file inside, install it, and it's ready to run. No hard setup. And here's the best part for your business. We show you how to point this loop at the stuff that actually brings in customers. Your landing pages, your welcome emails, your follow-ups, four coaching calls every week where we build this loop with you live and aim it at your own leads and content. Daily step-by-step tutorials and a room of business owners running Hermes and this exact loop right now, so you're never stuck. Link in the comments and description or go to the AI Profit Boardroom. Okay, back to the loop. Let me show you what a real run looks like because the numbers make it click. Round one, the work scores an A out of 100. Rough. Round two, it jumps to 85. Better. Round three, it hits 100. Perfect. It passes the gate and ships better and better on its own. That's the magic. You're the customer here and the customer should never be the quality control. But with normal AI, you always are. This loop takes that job off your plate. And notice what happened between round one and round three. The judge didn't just say bad, try again. It said why. It pointed at what was wrong. The headline was weak here. This part was the builder fixed those exact things. That back and forth is the whole engine. Two brains passing the work between them until it's right. Now, here's a smart money-saving move most people miss. You don't need your best AI for the building part. Building is just building. So, you can use a cheaper, faster AI to crank out drafts. Then you save your strong top AI for the judge because judging quality is the hard part. Think about why that's clever. The builder might run 10 times before the work is perfect. If every one of those runs used your most expensive AI, that adds up fast. But the judge only needs to be sharp. So, you put your strong AI where sharpness matters and your cheap AI where it's just cranking out drafts. Same great result, way less cost. And you might ask, what if the judge gets it wrong sometimes? Good question. Here's the answer. The judge doesn't need to be perfect. It just needs to be separate. A separate grader holding your goal will catch the obvious stuff every time. That every tiny thing, but it'll catch the ignored instruction, and that's the stuff wrecking your day anyway. Now, let's talk about the shapes this loop can take because there's more than one. The first is the simple loop. One builder, one judge, round and round until it passes, clean and easy. This is where you start, and if you never went week. The second is a team of agents. builder and one judge, you get a whole crew. Say you're making a video to bring You'd have a planner, a writer, a builder, and a judge who checks the final thing. You drop in the task, it gets split into smaller jobs, and each agent handles its piece. Then the judge signs off. It's like a real film crew, calls in sick. The third one is my favorite. It's a group chat between your come up with a lead magnet that gets more business owners into our AI forth. They talk to each other, they check each other. And when something plugged straight into your build. And here's a detail that's bigger than it sounds. Every single thing you build gets saved in its own workspace, so it made something great with AI and then lost it forever in a wall of messages? A saved workspace fixes that. Everything has a home. So, which shape do you use? Easy rule, simple job, use the simple loop. Big job with lots of parts, use the team. Fuzzy idea you want to shape, use the group chat. And this is where Hermes comes in. Hermes is a free, open AI agent from a group called News this. It runs on its own in the background. It has a built-in timer, so few minutes. It remembers stuff between runs, and it can build its own little skills over time. That last part is a big deal. Most AI forgets everything the second you close the tab. Hermes remembers. It gets a little smarter picture of what that looks like. You set Hermes to check your landing page every 15 minutes. If everything's fine, it logs it and stops. If something breaks, it opens a fix loop, patches it, checks its own work, and only stops when the doing something else. Now, think about the gap this creates. While one person is still copying and pasting into a chat window all afternoon, you've got agents the clock. That's the gap, and it's growing every single day. Every week you wait, the people using this pull further ahead. So, the best time to learn it is to give you an edge. But look, I'll be honest with you. There are a couple of catches. If your goal sentence is weak, the loop will happily pass weak work. The loop only meets the bar you set, so set a real bar, and if you let it run keep going and going. So, you cap it. Say stop after 20 rounds. Simple. loop run long, and that's really the whole thing. You set the goal, the builder builds, the judge checks, the loop runs while you go live your life.
