DESCRIPTION

Sorts a piece of text into categories you define on the fly, no training or fixed label set required. Send text plus labels (2 to 25 caller-supplied categories), an optional multi_label flag to allow more than one match, and optional label_descriptions to disambiguate close labels; get back results with a calibrated confidence per label, a top_label, and a one-sentence reasoning for the call. Use it as a zero-shot text classifier, text classification API, content moderation router, or category and label sorter for tickets, reviews, and inbound messages.
