Choosing a model

How to pick the right AI model for your study.

Explains model selection trade-offs: latency vs. richness vs. cost. Recommends running short A/B pilots with multiple settings and provides heuristics for selecting model size based on study goals.

Consider trade-offs between cost, speed, and depth. Smaller models are cheaper and faster; larger models provide richer follow-ups for nuanced open responses.

Run a short A/B pilot with different model settings to compare output quality before sending to your full sample.

Steps

  1. Define needs
    Decide if cost or depth matters more for your study.
  2. Pilot models
    Run A/B pilots to compare answer quality.
  3. Select and monitor
    Choose a model and monitor output for drift or quality issues.
