SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Lays out disciplined processes to design, implement, and validate evaluation schemes for LLMs and agents, turning vague assessment into structured, repeatable tests.

Core Features & Use Cases

  • Three-tier evaluation: golden cases, adversarial cases, and rubric-based grading to probe capability, robustness, and scoring stability.
  • Grader validation and threshold baselines to ensure meaningful progress signals and detect regressions over time.
  • CI-friendly wiring and documentation to enable reproducible experiments, dashboards, and evidence collection.

Quick Start

Design an eval suite for a given LLM capability using golden, adversarial, and rubric cases and validate the grader with human labels.

FAQPage Schema
How do I design an evaluation framework for LLM performance?

To design an LLM evaluation framework, structure your tests into golden cases, adversarial cases, and rubric-based grading to probe capability, robustness, and scoring stability across offline and online scenarios.

What is rubric-based grading for LLMs?

Rubric-based grading for LLMs is an evaluation method that uses structured scoring criteria to assess model outputs. It validates grader stability against human labels to detect hallucination, drift, and capability regressions.

How do I validate LLM graders against human labels?

Validate LLM graders by establishing threshold baselines and comparing grader outputs against human-labeled golden cases. This ensures meaningful progress signals and detects regressions over time.

Can I integrate LLM evaluation into CI pipelines?

Yes, you can integrate LLM evaluation into CI pipelines using reproducible wiring and documentation. This enables automated regression testing, evidence collection, and dashboards for ongoing model experiments.

What metrics should I track to detect LLM drift and hallucination?

Track baseline metrics across grounding, hallucination, drift, latency, and cost. Use golden and adversarial cases to probe these capabilities and establish threshold baselines for detecting regressions.

What's the best way to structure benchmark datasets for LLM agents?

Structure benchmark datasets using a three-tier approach: golden cases for baseline capability, adversarial cases for robustness, and rubric cases for scoring stability to ensure comprehensive agent evaluation.
