Evaluation Harnesses.

Generative AI, scoped to the shape of the problem it solves.

Continuous, automated evaluation pipelines for production generative-AI systems.

Use-case context

Every generative-AI system in production needs an evaluation harness before it can be trusted to ship changes, and most organisations either skip this step or hand-roll a spreadsheet of prompts that goes stale within a sprint. The result is a model that silently regresses on the cases that matter while looking fine on the cases someone happened to test by hand. We build evaluation harnesses that combine labelled gold sets, LLM-as-judge graders calibrated against human judgement, programmatic checks (format, schema, citation grounding), and red-team adversarial suites. The harness runs in CI on every model, prompt, or pipeline change and blocks deploys on regression against the defined quality gates. Meta-evaluated by inter-rater agreement between the harness and human reviewers on a stratified sample, plus the harness's ability to catch regressions in deliberate adversarial replays. The harness itself is treated as a tested artefact, not a one-off script. We do not certify that an evaluation harness is "enough" for a given regulatory regime — we build the harness against the criteria your risk and compliance owners specify, and they retain accountability for sign-off. In our coverage footprint this lands first across financial services, healthcare, legal — the sectors where the data shapes and evaluation criteria line up cleanly with what this use-case actually measures.

Data shape

Labelled gold sets curated with your subject-matter experts, historical incident and regression cases, adversarial prompts assembled by red-teamers, and the CI pipeline that already gates deployments.

Where we draw the line

We do not certify that an evaluation harness is "enough" for a given regulatory regime — we build the harness against the criteria your risk and compliance owners specify, and they retain accountability for sign-off.

Why work with Veso AI on evaluation harnesses

Measured

Evaluation, not opinion

Meta-evaluated by inter-rater agreement between the harness and human reviewers on a stratified sample, plus the harness's ability to catch regressions in deliberate adversarial replays. The harness itself is treated as a tested artefact, not a one-off script.

Fixed-fee

After paid discovery

Two-week discovery assembles the labelled evaluation set with your subject-matter experts, then converts into a fixed-fee proposal with explicit gates.

Your repo

Your IP, day one

Code, infrastructure-as-code, evaluation harness, and runbooks land in your accounts — no vendor lock-in on the data, models, or evaluation history.

FAQ

Evaluation Harnesses — frequently asked questions

How is success measured for evaluation harnesses engagements?

Meta-evaluated by inter-rater agreement between the harness and human reviewers on a stratified sample, plus the harness's ability to catch regressions in deliberate adversarial replays. The harness itself is treated as a tested artefact, not a one-off script. The evaluation harness is part of the deliverable, not an afterthought — we build it during the engagement so your team can run it against the next prompt, model, or pipeline change without us.

Where does Veso AI NOT apply evaluation harnesses?

We do not certify that an evaluation harness is "enough" for a given regulatory regime — we build the harness against the criteria your risk and compliance owners specify, and they retain accountability for sign-off. This is a deliberate trust boundary, not a capability gap — we are equipped to build the systems we decline to build, and we decline to build them because the risk-to-value ratio in those surfaces does not justify it.

Which industries does evaluation harnesses apply to?

In our coverage footprint, evaluation harnesses most commonly lands in financial services, healthcare, legal, insurance. The specific deployment shape varies by industry — data shapes, evaluation criteria, and regulators differ enough that we re-scope each engagement against the sector it lands in.

What data shape do you need to start a evaluation harnesses engagement?

Labelled gold sets curated with your subject-matter experts, historical incident and regression cases, adversarial prompts assembled by red-teamers, and the CI pipeline that already gates deployments. During the paid two-week discovery we map the actual data surface — what exists, what is labelled, what residency posture it carries — and the proposal for the next gate is shaped against that, not against an assumption.

Which Veso AI services ship evaluation harnesses?

evaluation harnesses ships under our Generative AI Consulting, Custom Software Development, AI Integration Services service lines, depending on the integration surface and the build-vs-platform trade-off. Most engagements draw on more than one — the boundary between consulting, custom build, and integration is a scoping decision we make explicit during discovery.

How does a evaluation harnesses engagement typically start?

With a paid two-week discovery: workshops with leadership and operators, an evaluation-set assembled with your subject-matter experts, and a fixed-fee proposal for the next gate. The evaluation set anchors every subsequent decision — model choice, prompt strategy, retrieval design — so quality is measurable from week one, not from go-live.
