What you'll learn
Find out what your current checks don’t see
Run one instruction through several models blind. The spread of answers shows the failures your product has that hide.
Annotate outputs to find how the AI actually fails
Learn how to zoom into real AI answers and provide qualifiable feedback into an error analysis
Turn those notes into a rubric you can run
Cluster the failure notes and convert the persistent ones into checks you can score automatically
Why this topic matters
Most AI products ship with a rubric that was written before anyone read an output. It measures imagined problems in vague words, so it passes everything and catches nothing. The rubric your product is actually missing is the one built from how your AI really fails.
In 30 minutes we build it from scratch: real outputs, real failures, real criteria. No existing evals, no benchmarks, no setup required.
