Evaluation methods for every need

A library of pre-built evaluators plus support for custom evaluators across multiple paradigms.

LLM-as-Judge

Use powerful LLMs to evaluate output quality

Statistical

BLEU, ROUGE, cosine similarity & more

Programmatic

Custom code-based evaluation rules

Human Scoring

Managed human evaluation pipelines

Comprehensive evaluation suite

Every tool to test your AI

From automated simulations to human-in-the-loop evaluation, we have everything you need to ensure quality at every stage.

AI-Powered Simulations

Test your agents across diverse scenarios with AI-generated user simulations. Cover edge cases, adversarial inputs, and multi-turn conversations at scale.

Learn more

Custom Evaluation Metrics

Define the metrics that matter for your use case relevance, faithfulness, toxicity, format compliance, and more. Use pre-built or create custom evaluators.

Learn more

CI/CD Automation

Integrate evaluations seamlessly into your CI/CD workflows. Block deployments that don't meet quality thresholds and track quality over time.

Learn more

Human-in-the-Loop

Simplify and scale human evaluation pipelines. Assign reviews, collect annotations, and combine human judgment with automated scoring.

Learn more

Experiment Analytics

Generate reports to track progress across experiments. Compare runs, identify regressions, and share insights with stakeholders.

Learn more

Safety & Guardrails Testing

Test your safety guardrails against adversarial attacks, prompt injections, and harmful content. Ensure your agents are safe before production.

Learn more

From reactive to proactive quality

Shift left on AI quality. Catch issues in development, not in production. Reduce time to production by 75%.
