What is an Eval?
Definition: An Eval (short for evaluation) is a
structured test that checks how well your Al
system performs. It helps you measure
quality, reliability, and correctness across
scenarios.

Scorer Tips
Use a higher-quality model for scoring, even if the prompt uses a cheaper
model. Scorers benefit from better reasoning and nuance.
Treat scorers like judges: evaluate intent match, style accuracy, and
overall output quality: -not just correctness.
Break scoring into multiple focused scorers (e.g., accuracy, Creativity,
formatting) to pinpoint issues.
Test scorer prompts in the Playground before use. Try strong and weak
outputs to refine scoring reliability.
Avoid overloading the scorer prompt with context. Focus it on the relevant
input and output for fair, consistent evaluation.

Slide-Derived Subjects To Review
Subject extraction uses video title, related session titles/descriptions, transcript context, and OCR text when available. OCR is best-effort and should be reviewed against the embedded slide images.
