# Prove every AI change is better before you ship it.

> Evaluate LLMs, agents, RAG applications, and traditional ML systems across quality, safety, performance, cost, and compliance.

## Evaluation has become an enterprise control.

Testing AI is no longer only an engineering exercise. Emerging regulations, risk frameworks, and enterprise policies increasingly require organizations to demonstrate how systems were evaluated, which standards they met, and who approved them for use.

Openlayer preserves every dataset, test, result, version, and decision, so teams can improve performance and produce the evidence required for governance, customer reviews, and audits.


## You can’t tell if a change helped or hurt.

Teams change a prompt, swap a model, update a dataset, or modify an agent workflow without a repeatable way to measure the result. A change may improve quality while quietly increasing cost, latency, bias, or failure rates.

Evaluation is often spread across homegrown harnesses, notebooks, prompt registries, and static documents. Results are difficult to compare, reproduce, or connect to what ultimately shipped.

### No repeatable way to compare AI changes.

Teams cannot reliably determine whether a new prompt, model, dataset, or architecture improved the metrics that matter without degrading something else.

### Evaluation results are scattered and difficult to reproduce.

Test configurations, datasets, results, and model versions live across notebooks and documents with no reliable system of record.

### Evidence has to be reconstructed after the fact.

When governance, customers, or auditors ask how a system was tested, engineers spend days finding results and proving which version they belong to.


## Evaluation engineering can trust. Evidence governance can use.

Openlayer gives engineering teams the depth to evaluate LLMs, agents, RAG applications, and traditional ML. Compare versions, configure custom metrics, and measure performance across datasets and cohorts.

Every result stays connected to its system version, configuration, policy, and approval. Engineering gets rigorous evaluation. Governance gets continuously updated evidence.


## By the numbers

| Stat | Meaning |
| --- | --- |
| 10x | faster iteration through systematic testing, not trial-and-error prompt changes |
| 100% | of evals automatically tied to policies required by compliance |
| 6x | faster deployment after standardizing on Openlayer |


## Evaluation for every type of AI system

### LLM-as-judge evaluations

Model-as-judge scoring for answer relevancy, faithfulness, hallucination detection, and brand tone. Returns a score and written rationale; judge model selectable.

### 175+ out-of-the-box evals

Evaluate quality, safety, security, performance, cost, fairness, and compliance with configurable tests ready to run across your AI systems.

### Fairness and bias testing

Identify performance disparities across demographic, geographic, customer, and patient cohorts using configurable subpopulation analysis.

### Agentic metrics

Measure whether agents complete assigned tasks, select and use tools correctly, follow required steps, and recover successfully when workflows fail.
