SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automatically evaluate LLM outputs by combining automated metrics, human feedback, and benchmarking to quantify performance and guide improvements.

Core Features & Use Cases

  • Automated Metrics: BLEU, ROUGE, METEOR, BERTScore, perplexity, and retrieval metrics.
  • Human Evaluation: Dimensional ratings (accuracy, relevance, clarity, safety) with a structured checklist.
  • Benchmarking & Guardrails: A/B testing, LangSmith integration, and baseline tracking for continuous improvement.

Quick Start

Run a quick evaluation on your latest model using prebuilt metrics and a human-judgment checklist.

FAQPage Schema
How do I evaluate LLM outputs systematically for model comparisons?

To evaluate LLM outputs systematically, you can combine automated metrics like BLEU and ROUGE with human evaluation guidelines and benchmarking workflows to produce repeatable performance assessments for model comparisons.

What automated metrics can I use to measure LLM quality?

You can measure LLM quality using automated metrics including BLEU, ROUGE, METEOR, BERTScore, perplexity, and retrieval metrics to quantify performance and guide improvements.

How do I set up human evaluation for LLM accuracy and safety?

To set up human evaluation for LLM accuracy and safety, apply a structured checklist providing dimensional ratings for accuracy, relevance, clarity, and safety to systematically assess outputs.

Does LangSmith integration work with LLM benchmarking workflows?

LangSmith integration works with LLM benchmarking workflows by supporting A/B testing and baseline tracking to monitor production performance and enable continuous improvement.

What is the best way to run A/B testing for prompt tuning?

The best way to run A/B testing for prompt tuning is to use benchmarking workflows that track baselines and apply automated metrics alongside human feedback to quantify performance changes.

Can I monitor production LLM performance using prebuilt evaluation metrics?

You can monitor production LLM performance by applying prebuilt automated evaluation metrics and human-judgment checklists to continuously benchmark output quality and track baselines.
