Guide

AI product strategy starts with which jobs tolerate a probabilistic system. LLMs are strong when the task has messy language or perception in, and structured or checkable work out. They are weak when you need perfect recall of private facts without retrieval, or zero-tolerance correctness with no verifier.

Treat the model like a powerful, unreliable junior employee: hire it for the right tasks, measure its work, and put guardrails on irreversible actions.

Concept

A verifier is anything that can check the model's output without needing another unverifiable judgment — unit tests for code, JSON schema validation, citation overlap, human approval, or a domain rule engine. AI products without verifiers are demos. AI products with verifiers can set SLAs.

The big idea

A practical filter:

CriterionPrefer AI when…Avoid / constrain when…
Value of successMinutes saved, deals unblocked, tickets deflectedNovelty demo with no workflow owner
Cost of errorUser can review; undo exists; stakes moderateIrreversible money, medical or legal action without a human gate
VerifiabilityTests, schemas, citations, graders exist"Sounds good" is the only check
FrequencyHappens often enough to learn and amortize UXOne-off that never builds a feedback loop

A smoke alarm is useful because a false beep is cheap and a missed fire is not. Flip that and you have a bad AI job: auto-issuing refunds from email sentiment. The analogy breaks when the "beep" itself is expensive (a bad customer email, a wrong medical note) — then you need a human gate, not just a model.

Walking through two jobs

Good fit: "Draft a reply from this ticket + policy docs; agent sends only after approve." Error cost is bounded. The verifier is the human click. Value is handle time.

Poor fit: "Auto-issue refunds from email sentiment alone." Error cost is cash. No reliable verifier. Regulators and customers will not accept plausible mistakes.

Say no when a deterministic rules engine or search already solves 90% of the job; when the demo requires a human silently fixing outputs before the customer sees them; when you have no path to a verifier and the stakes are high; or when the only differentiation is the underlying model brand, which a competitor can swap tomorrow.

AI can still appear later as an assist layer on a solid classical product. Nail the system of record, then accelerate the workflow. That sequencing often beats "AI-first" skimming of a domain you do not own.

Common mistakes

  • Starting from the model. "We have GPT access" is not a use case.
  • Skipping the verifier. If you cannot assemble a labeled set, you do not understand the job well enough to sell it.
  • Selling theater. A human fixing outputs offstage is not a product.

Check yourself

You want to auto-send support replies with no human in the loop. What must exist first?

A verifier and a quality bar — for example citation faithfulness on a labeled set — plus a kill switch.

Search already finds the right policy 90% of the time. Should you replace it with an LLM?

Probably not. Add AI as an assist on the remaining mess, or leave the deterministic path.

Key takeaways

  • Choose AI jobs with high value, tolerable errors and a verifier.
  • Cost of error decides whether the model drafts, suggests or is blocked.
  • Classical software first is often the right sequence; AI later as an accelerator.
