A/B Testing Your AI: The Prompt Experimentation Framework

Your prompts are product decisions. They deserve the same rigor as your UI. Here's how to A/B test prompts like you test buttons.

A/B Testing Your AI: The Prompt Experimentation Framework

Prompts Are Product

Every prompt you write is a product decision. The tone. The structure. The examples. The guardrails.

Yet most teams treat prompts like code comments—write once, hope for the best.

Your prompts deserve A/B testing.

The Framework

1. Define Your Metric

Before testing prompts, know what you’re optimizing:

  • User satisfaction (thumbs up/down)
  • Task completion rate
  • Follow-up question frequency
  • Time to value

2. Create Variants

Don’t test wildly different prompts. Test specific hypotheses:

Hypothesis: Adding examples improves output quality

Control: “Summarize this document.”

Variant: “Summarize this document. For example: ‘The Q3 report shows revenue increased 15% driven by enterprise sales.‘“

3. Split Traffic

Use Clayva’s experimentation:

clayva experiment create "prompt-with-examples" \
  --metric "user_satisfaction" \
  --rollout 50%

4. Measure Everything

Track more than your primary metric:

  • Latency (longer prompts = slower responses)
  • Token usage (cost implications)
  • Error rates
  • User engagement post-response

5. Ship Winners Fast

With Clayva, you can see statistical significance in hours, not weeks. When a variant wins, ship it immediately.

Real Results

One team we worked with improved their AI assistant’s satisfaction score from 72% to 89% through systematic prompt testing. The winning change? Adding “Let me think step by step” to complex queries.

Small changes. Rigorous testing. Massive impact.
