/**
 * Pre-trained TFJS toxicity model.
 *
 * It detects whether text contains toxic content such as threatening language,
 * insults, obscenities, identity-based hate, or sexually explicit language.
 *
 * Usage:
 *
 * ```js
 * // Load the model with options (optional. See below for docs).
 * const model = await tfTask.SentimentDetection.Toxicity.TFJS.load();
 *
 * // Run detection on text.
 * const result = await model.predict('You are stupid');
 * console.log(result.sentimentLabels);
 *
 * // Clean up.
 * model.cleanUp();
 * ```
 *
 * By default, the model returns the prediction results of the following
 * sentiment labels:
 *
 * - toxicity
 * - severe_toxicity
 * - identity_attack
 * - insult
 * - threat
 * - sexual_explicit
 * - obscene
 *
 * Refer to `tfTask.SentimentDetection` for the `predict` and `cleanUp` method,
 * and more details about the result interface.
