Field notes
The API accepts examples with either one label or multiple labels, and optional group identifiers for related conversations or documents. The page says 10,000 examples train in about a minute on CPU; classification requests accept up to 50 texts, with larger batches potentially queued under heavy concurrent load. Its evaluation report is described as using examples the model has not seen.
