# Is Your AI Bill Bigger Than It Needs to Be?

One week. Fixed price. A written report on where your model spend goes, what you can cut without your users noticing, and how to move to newer models without breaking what works. For teams with AI already in production. If you go ahead with the changes, the fee comes off the price.

AI Cost and Model Review

$4,500fixed

One week. A written report plus a call. Credited in full against the work if you engage us within 90 days.

Ask a Question

## What the Report Contains

The same six sections every time. The price is fixed, so the shape is fixed. A section with nothing to fix is a finding too, and it gets written down.

### What you spend, and on what

Your model bill broken down by feature, model, customer and tool call, ending in a cost per task: what one support answer, one document processed or one agent run actually costs you today. Most teams know the monthly total and very little below it.

### Where the money goes that does not need to

Ranked by monthly saving, biggest first. Prompt caching, context that gets sent and never used, the wrong model for simple steps, retries, work that could run through a batch API, and self hosting where the volume justifies it. Each item comes with an estimated saving and the quality risk of making the change.

### Whether you can change models safely

A cheaper or newer model is only a saving if quality holds. We check what evaluation you have. If there is none, we build a small evaluation set from your own traffic during the week, so every change in the report can be tested before it ships.

### Which model deadlines apply to you

The models you depend on that are scheduled for retirement, the dates, and the newer models worth moving to, with what each move is likely to do to cost, latency and quality on your workload.

### What the changes cost and how long

A scoped plan for the changes worth making, in days of engineering, set against the monthly saving each one buys. Some changes pay back in a week. Some never do, and the report says which.

### A proposed first milestone

If you go ahead: what gets changed first, by when, and the numbers that tell both sides it worked, written as a target cost per task at a quality score you agree in advance.

## Why This Exists

The first version of an AI feature is built to work. Nobody tunes what it costs, because there are no users yet. Then usage grows, the bill grows faster, and the system that was fine at a hundred requests a day is now a line item someone in finance asks about.

At the same time the models underneath keep moving. Providers retire versions on a schedule, and new models arrive that are cheaper or better at your task, sometimes both. Switching without a way to measure quality is a gamble, so most teams stay where they are and keep paying.

A week is enough to find out what each request costs, where the waste is, and which changes are safe. You can make them with us, with your own team, or with someone else.

Still on a prototype? The [Production Readiness Review](https://vindler.solutions/production-readiness-review) is the same price and the same shape, aimed at getting a product ready for its first real users.

## What We Need From You

Four things, all of them on day one. The week starts when the last of them arrives, not when you sign.

-   Read-only access to your model provider usage and billing (OpenAI, Anthropic, Bedrock, Vertex or Azure)
-   Read-only access to the code that calls the models
-   Traces or logs if you have them (Langfuse, LangSmith, Datadog or similar), or a sample of real requests
-   A 45 minute walkthrough call, plus your written answer to: which features matter most, and what quality is the minimum

Thirty minutes, no charge. Tell us what you run and roughly what it costs. We will say whether the review is worth it at your volume, and say so plainly if it is not.

### Or Send Us the Details

Which models you use, roughly what you spend each month, and what worries you about it. We reply within 24 hours.

{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What exactly do I get for $4,500?","acceptedAnswer":{"@type":"Answer","text":"A written report covering all six sections above, delivered as a PDF, plus a live call of up to an hour to walk through it. The report is yours to keep, use, and forward to anyone, including your own team and other suppliers. The price is fixed and does not change with the size of your bill or your system."}},{"@type":"Question","name":"Do I have to hire you afterwards?","acceptedAnswer":{"@type":"Answer","text":"No, and the report is written on that assumption. Most of the changes it recommends can be made by your own engineers, and it says how. If you do engage us for the work within 90 days, the full $4,500 is credited against it."}},{"@type":"Question","name":"Is it worth it for a small bill?","acceptedAnswer":{"@type":"Answer","text":"If you spend less than a few thousand dollars a month on models, the saving alone may not repay the review, and we will tell you that on the first call. It can still be worth it if a model you depend on is being retired, or if your usage is about to grow and you want to know what it will cost before it does."}},{"@type":"Question","name":"Do you guarantee a saving?","acceptedAnswer":{"@type":"Answer","text":"No. The report gives an estimated saving for each change, with the evidence behind it, and says which estimates are firm and which depend on testing. A guaranteed percentage would have to be either padded or made up, because it depends on your traffic and your quality bar."}},{"@type":"Question","name":"Will a cheaper model make our product worse?","acceptedAnswer":{"@type":"Answer","text":"It can, which is why every recommendation is tested against an evaluation set built from your own requests before we suggest shipping it. Where a change saves money but costs quality, the report says so and lets you choose."}},{"@type":"Question","name":"How long does it take?","acceptedAnswer":{"@type":"Answer","text":"One week from the day we receive the last piece of access, not from the day you sign. The walkthrough call is scheduled within five business days of delivery, at a time you choose."}},{"@type":"Question","name":"Do you negotiate with OpenAI or Anthropic for us?","acceptedAnswer":{"@type":"Answer","text":"No. We change what your system sends and to which model. Committed-use and enterprise discounts are between you and your provider, though the report tells you what volume you are at so you can ask."}},{"@type":"Question","name":"What happens to our code and data?","acceptedAnswer":{"@type":"Answer","text":"It stays yours throughout, and we delete or return it on request when the engagement ends. Request samples used for the evaluation set stay in your environment where possible. We do not name you publicly without your written permission, and we do not use your code or data to train any machine learning model. All of that is in the agreement."}}]}
