Shipping AI features that actually work

It takes an afternoon to build an AI demo that wows a room. It takes real engineering to ship one that holds up when thousands of users push it in ways you didn't script. The gap between those two things is where most AI initiatives stall — and it has very little to do with which model you picked.

Start with the problem, not the model

The strongest AI features begin with a concrete, valuable task — summarize this, route that, draft a reply — not with 'let's add AI.' Pick a job where being right matters and being wrong is recoverable, and you'll have something worth shipping. Lead with the model and you'll spend months looking for a problem to justify it.

Ground the model in your data

A model on its own knows the public internet, not your business. Retrieval-augmented generation — pulling the right context in at query time — is what turns a generic chatbot into something that answers from your documents, your policies, your data. Most 'the AI made something up' problems are really 'the AI was never given the facts' problems.

Evaluation is the product, not an afterthought

You can't improve what you can't measure, and 'it looks good' doesn't survive contact with real users. Build an evaluation set of real inputs and expected behavior early, and run it on every change. Without it, every prompt tweak is a guess and every model upgrade is a gamble.

Design for being wrong

AI features fail differently than normal software — confidently, fluently, and occasionally. Keep a human in the loop where stakes are high, make it easy to correct and undo, and set guardrails on what the system is allowed to do on its own. Trust is earned by handling the bad cases gracefully, not by pretending they won't happen.

Own the economics

Token costs, latency, and rate limits are real constraints that shape what's viable. Run smaller models where they suffice, cache aggressively, and keep the option to swap providers — on AWS, Bedrock makes that switch a config change rather than a rewrite. The goal is an AI feature whose value clearly exceeds what it costs to run, every single day.
