How to pick the right AI model for your study.

QuestionPunk offers three AI model tiers: Haiku (fast and economical), Sonnet (balanced), and Opus (deepest). This guide explains the trade-offs.

Steps

  1. Understand the options
    Haiku: Fastest responses, lowest cost. Good for simple follow-ups and high-volume studies.
    Sonnet: Balanced speed and depth. Recommended for most research use-cases.
    Opus: Richest follow-ups, highest cost. Best for deep qualitative interviews where nuance matters.
  2. Select in survey settings
    Choose the model in the AI interviewer settings for each survey. You can set different models for different interview questions within the same survey.
  3. Pilot and compare
    Run a short A/B pilot with different model settings to compare output quality before sending to your full sample.

Consider trade-offs between cost, speed, and depth. Haiku is cheapest and fastest; Opus provides the richest, most nuanced follow-ups for complex qualitative research.

Sonnet is the recommended default for most studies. It provides good follow-up depth at reasonable cost and latency.

Run a short pilot with 5-10 respondents using different model settings to compare output quality before committing to your full sample.
