What does this agent skill do?

Comparative Evaluation

Absolute quality scores are useful but limited. Comparative evaluation — putting outputs side by side and asking which is better — often reveals quality differences that rubrics miss.

Comparison Methods

  • A/B testing: Show different users different versions and compare outcomes
  • Side-by-side evaluation: Show evaluators two outputs for the same input and ask which is better
  • Preference ranking: Show evaluators multiple outputs and rank them from best to worst
  • Paired comparison: Compare every pair of options to build a complete ranking
  • Elo rating: Use tournament-style comparisons to develop continuous quality scores

Designing A/B Tests for AI

A/B testing AI is different from A/B testing UI:

  • Variance is high: The same prompt can produce different outputs, so you need more samples
  • Context matters: The same change might help for one task and hurt for another
  • Metrics lag: AI quality changes may take time to show up in user behavior
  • Interaction effects: A change to one part of the conversation affects all subsequent parts Design A/B tests with:
  • Sufficient sample sizes to account for output variance
  • Segmentation by task type and user experience level
  • Multiple metrics (don't optimise for one at the expense of others)
  • Guardrails to catch severe quality regressions quickly

Side-by-Side Evaluation Design

For human evaluation of AI outputs:

  • Blind evaluation: Evaluators shouldn't know which version is which
  • Consistent inputs: Compare outputs generated from the same input
  • Structured criteria: Give evaluators specific dimensions to compare on, not just "which is better"
  • Multiple evaluators: Use at least 3 evaluators per comparison for reliability
  • Diverse inputs: Test across a representative sample of real user inputs

When to Use Comparative vs. Absolute Evaluation

  • Comparative: Best for choosing between alternatives, detecting subtle quality differences, and model selection
  • Absolute: Best for measuring against a standard, tracking progress over time, and certification

Design Artefacts

  • A/B test design templates
  • Side-by-side evaluation protocols
  • Evaluator instructions and rubrics
  • Sample size calculators for AI experiments
  • Comparison result analysis frameworks
