In low-stakes scenarios—like a chatbot recommending a restaurant—an AI mistake is merely annoying. In high-stakes scenarios—like generating a legal contract, summarizing a medical record, or approving a loan—that same mistake becomes a business risk. This is the Trust Gap . Stakeholders expect zero-error behavior , yet probabilistic systems like LLMs cannot offer absolute guarantees. Waiting for a “perfect” model is not a strategy. It is a dead end. The real solution is architectural. To deploy AI safely, we must stop trying to replace humans and start designing systems that amplify them. We need a Human Brake: a workflow where AI does the heavy lifting, but a human expert acts as the final commit gate before anything irreversible happens. Here’s how to design that review loop on Databricks using the MLflow Review App—and turn AI from a liability into a force multiplier.

Most enterprise AI today is stuck in the “Read-Only” trap . Teams have built chatbots that can read documents (RAG) and query databases (text-to-SQL). That’s real progress. But when you ask, “Update the inventory count,” or “Process a refund for Order #992,” the answer is usually the same: “I cannot perform that action.” That’s the ROI ceiling. A read-only AI behaves like a research assistant. A read-write AI starts to look like a digital employee. So why aren’t more teams building agents that can take action? Because the fear is justified. Engineering leaders don’t want a probabilistic model touching systems like SAP, Salesforce, or Oracle. One bad loop could trigger 1,000 refunds. One hallucinated digit could change an invoice by an order of magnitude. The blast radius is simply too high. Still, if we want real value, we have to move from “chat” to “work.” Here’s the pattern that makes that shift possible on Databricks: Unity Catalog Functions + the “Human Brake.” The “Undo” Problem:...
