There was pressure to put AI into everything, so a model got wired into workflows that are perfectly deterministic. Now you fight its non-determinism every day, the inference bill climbs, and you have added latency and liability for no real gain. Just because you can use a model does not mean the workflow ever needed one.
This is one of the few challenges on this page where the honest fix is to use less of what everyone is selling, not more.
Why this happens
The market pressure is real: boards, customers, and competitors all want to hear the word AI. So teams reach for a model as the default tool, even for tasks that are rules, lookups, validations, and transformations, work that plain software has done reliably and cheaply for decades.
A deterministic task run through a probabilistic model does not get better. It gets slower, more expensive, harder to test, and occasionally wrong in ways a simple function never would be. The model is doing a job a switch statement could do, and charging you per token to do it worse.
What it’s costing you
You are paying three ways at once:
- Inference spend that scales with usage, for work a one-time build would have finished.
- Engineering time spent babysitting non-determinism, retries, and edge cases the model invents.
- Latency and liability added to a path that used to be instant and predictable.
None of it buys you anything a customer can feel. It is pure overhead, dressed up as innovation.
What good looks like
AI reserved for the genuinely non-deterministic steps, the ones that involve language, judgment, or ambiguity a rule cannot capture. Reliable deterministic software everywhere else. Lower operating cost, far less to babysit, and much less liability, because the risky component is only present where it earns its place.
How Density fixes it
We help teams ship AI, so the first thing we will tell you is where not to use it. The AI Readiness Assessment ($2,500, two weeks, founder led) maps your workflow step by step and marks which parts genuinely need a model and which are quietly costing you money. Often most of it never needed one. You walk away with a ranked 90 day roadmap with ROI and TCO, including the operating cost you would save by moving deterministic work back to real software.
Where a build is warranted, a Forward Deployed AI Engineer ($9,500 a month, deployed in 7 to 10 days, 120 day replacement guarantee) rebuilds it the right way inside your codebase: AI on the non-deterministic steps, plain engineering on the rest. This is our actual belief, not a sales angle. We have shipped production software for US companies since 2016 at 96 percent retention, and using as little AI as the problem allows is how we keep systems cheap to run and easy to trust. The assessment fee is credited toward the engagement.
