Trustworthy AI Execution
Most AI disappointment comes from the same mistake: throwing a general-purpose model at a task and expecting production-grade results. "Close enough" works for drafting prose. It doesn't work when decisions have consequences.
Let AI Think, Let Code Execute
LLMs are good at understanding messy, unstructured information—reading a contract, interpreting an email, figuring out what a customer is asking for. They're bad at doing math, enforcing constraints, and producing identical results twice. The trick is to use each for what it's good at.
Let AI read an invoice and extract the line items. Then hand those values to deterministic code that checks the totals, applies tax rules, and writes to the ledger. AI handles the fuzzy front end: parsing natural language, classifying intent, pulling structure from chaos. The moment you have structured data, you switch to computation—deterministic code that runs the same way every time.
The Deterministic Side
Most structured decisions don't need AI at all. If a vendor name maps to a category, write a rule. If an amount threshold triggers an approval, write a rule. Rules are fast, auditable, and 100% accurate for the cases they cover. In most business processes they handle 60–80% of cases outright. AI should only touch the genuinely ambiguous remainder—and when it does, validation catches what it gets wrong. Does the output fall within the expected range? Does it contradict other data points? Does it break a business rule that should always hold? These checks run automatically after every AI decision and route failures back for review. (For a deeper look at this in practice, see how to handle LLM hallucinations in report writing.)
Use the Right Model
When you do need AI, use the right kind. A general-purpose LLM knows a little about everything. A model fine-tuned on your specific data and trained on your team's historical decisions will dramatically outperform it. It doesn't hallucinate categories that don't exist. It knows the patterns and edge cases specific to your business. The difference between a generalist and a specialist who has seen ten thousand of your cases is enormous.
Close the Feedback Loop
Every human correction is training data. When someone overrides an AI decision, that correction feeds back into the system—a new rule, a new training example, an adjusted threshold. Your institutional knowledge becomes a living system that improves with every decision. Systems without feedback loops stay at the same accuracy forever. Systems with them get better every week.
The result isn't the 70–80% accuracy that gives AI a bad name. It's 99%+ with full auditability. The companies that get this right don't choose between automation and accuracy—they get both.
