Reflex

Classify text (realtime)

Run a Reflex over text and get a label back in ~90ms. Pass a single model for the flat {model, mode, classes} envelope, or models (an array) to run several classifiers over one shared prefill for {predictions}. Use a default Reflex name or a model you trained. Billed per event at the realtime rate.
