What happened

Bazaarvoice uses LLM-based evals to classify the outputs of its AI question-and-answer system as correct or incorrect, and to check whether two answers say the same thing. They validate the evaluators against a human-labeled set and then run them on much larger datasets instead of labeling manually.

Summary written by usedby from the source page, in English. The figures are those of Arize AI and Bazaarvoice, not ours.

  • a day and a half“The process took about a day and a half and came with the associated cost of manual labeling.”

For one experiment, Bazaarvoice sent 1,000 examples for human review. The process took about a day and a half and came with the associated cost of manual labeling. With LLM-based evals, Kratz says the same volume can be evaluated in about 10 minutes.
