AI Evaluation and Monitoring

KNOW HOWOFTEN ITIS WRONG

We build the tests and monitoring that tell you whether an AI feature is good enough to release and whether it stays that way, using evaluation sets drawn from your real cases.

01Our Approach

If you cannot say how often an AI feature is wrong, and in what way, you are not ready to change it or to trust it.

02Overview

Knowing how good your AI really is

  • 01Evaluation datasets
  • 02Failure taxonomy
  • 03Live monitoring

AI evaluation measures the quality of a model-driven feature against cases that represent real use, and monitoring keeps measuring once it is live. We build the dataset, define what correct means with your experts, classify the ways the system fails, automate the scoring and connect it to your release process and production logs.

It suits teams with an assistant, agent or extraction feature that seems to work and cannot prove it, and teams afraid to change a prompt or model because nobody knows what would break. Evaluation is not a one-time audit. It becomes part of how the product is developed, in the way automated tests are for ordinary software.

03What We Do

Capabilities, End to End

01
Evaluation dataset

We assemble examples from real conversations, documents and tickets, covering common cases, rare ones and known trouble spots, each with an expected result agreed by your experts.

02
Failure taxonomy

Errors are sorted into named types, such as invented facts, missed retrieval, wrong tool use or poor tone, so effort goes to the kinds that cost you most.

03
Scoring methods

Exact checks, rule-based checks and model-graded rubrics are chosen per task, and graders are themselves validated against human judgment before their scores are relied on.

04
Release gates

Every change to a prompt, model, tool or data source runs against the evaluation set, and a release proceeds only when agreed thresholds are met.

05
Production monitoring

Live traffic is sampled and scored, with dashboards for quality, refusals, latency and cost, and alerts when any of them drifts from its normal range.

06
Human review loop

Reviewers label a sample of real outputs in a simple tool, and confirmed failures are added to the dataset so the same mistake is tested for in future.

06How It Runs

From Kickoff to Launch

01
Define good
02
Build the dataset
03
Automate scoring
04
Monitor in production
01
Define good

With the people who own the outcome we write down what a correct, acceptable and unacceptable result looks like for each task, using real examples to settle disagreements.

02
Build the dataset

We gather and label representative cases, check that experts agree with one another on the labels and set aside a portion that is never used for tuning.

03
Automate scoring

Scorers are implemented and compared with human ratings until they agree closely enough to trust, then wired into the development workflow so that every change produces a report.

04
Monitor in production

Sampling, dashboards and alerts are switched on for live traffic, a review routine is agreed with your team and the first baseline report sets the figures future releases must beat.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Your AI feature works and you cannot prove it

The demo was convincing and users mostly seem satisfied, yet nobody can state an accuracy figure, complaints arrive as anecdotes and each prompt change is a leap of faith. You want numbers, known failure types and a warning when quality slips.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Fewer than most teams fear to start, and more as the product matures. A small, carefully chosen set that covers the main tasks and known problem cases already catches most regressions. It grows with every confirmed failure from production. Coverage matters more than size, so we check the set against the real mix of requests instead of chasing a headline number.

For many criteria, yes, provided the grader is checked. We write a clear rubric, have people rate a sample, and compare the grader's scores with theirs. Where agreement is high, the grader can run at scale. Where it is not, we refine the rubric or keep a human in that part of the loop. An unvalidated grader gives confident figures that mean little.

Quality on sampled outputs, the rate of refusals and escalations, response time, cost per request, tool errors and user feedback. We also watch the inputs, since a shift in what people ask often explains a fall in quality before any code changes. Alerts are set on trends, not on single bad answers, so the team is warned without being flooded.

Yes. Evaluation is largely independent of how a system was built. We need access to its inputs and outputs, ideally to logs and prompts, and time with the people who can judge correctness. An outside evaluation is often useful precisely because the builders are too close to the product to see its common failures clearly.

It turns a risky decision into a measured one. With a dataset and scorers in place, a new model or a cheaper one can be run against the same cases and compared on quality, speed and cost within a day. Without them, a switch is judged by a few manual tries, and regressions surface later through users. Providers retire models regularly, so the question always returns.
