“Our AI unit economics are getting worse, and nobody can say why.”

Last verified: October 2026· engagement

The bill grows with usage, it arrives as one line on a cloud invoice, and every proposed cut is a guess because nobody can see cost per route or per completed task. The first question is not how much you can save. It is whether the workload is big enough, and visible enough, for optimization to be worth an engineer’s time.

Is it worth fixing?

It usually is when several of these are true:

  • Eligible spend is large enough that a meaningful reduction is worth more over a year than the work costs. Below roughly $10k a month, a guide and a day of instrumentation usually beat an engagement.
  • Spend is growing faster than usage or revenue, so unit economics are moving the wrong way.
  • Nobody can attribute cost to a route, feature or customer, so cuts are being argued rather than measured.
  • There is a planning moment coming: a margin review, a budget cycle, credits expiring, or a price rise to customers.

What a first engagement looks like

  1. Free read

    A written read on where the spend is concentrated and whether it looks worth optimizing, from your rough spend and top routes. No call required.

  2. Paid diagnostic

    A fixed-price, read-only baseline week: cost per route and per accepted task, quality and latency, and a sized estimate per lever. Fixed price, quoted after the free read.

  3. Stop or go

    If the baseline shows the saving would not cover the work, we say so and you keep the attribution layer.

The accepted outcome is the test above: lower cost per accepted task on the in-scope routes, within agreed quality and latency limits, measured against a week-one baseline.The full acceptance criteria, exclusions and pricing terms are written out onthe engagement page, so you and procurement can see the finish line before any call.

Access and security

  • Read-only access to traffic logs or a gateway export for the baseline week; redacted is fine.
  • No production credentials, raw customer records or full prompt dumps are needed to assess fit.
  • Mutual NDA before any data access.

When we’d tell you not to buy

Our scarce resource is senior engineering attention, so we would rather say no early. We decline or refer when:

  • Spend is too small for any plausible saving to pay for the work.
  • The bill is dominated by a fixed commitment or reserved capacity, so the lever is commercial, not technical.
  • Nobody can grant read access to traffic or prompts.
  • The real goal is to cut quality to cut cost, with no way to measure what that does to users.

Questions

How much will we save?

Nobody can tell you honestly before seeing your traffic. We baseline cost per route and per accepted task in a read-only first week, size each lever against it, and only then set a target with you.

Is our spend big enough to bother?

As a rule of thumb, below about $10k a month of eligible spend, an engagement costs more than a year of any plausible saving. Use the calculator and the playbook instead; we will tell you the same thing if you ask.

Do we need to switch providers?

Rarely. Most of the saving is in routing, caching, batching and context control on the providers you already use.
