About

Clef is a 27B multimodal decision model that turns a state and a schema of typed questions into structured decisions. It can read state information as text, JSON, images, or video and return a probability for every allowed option of every question. The model supports a 65,536-token context window and vision inputs, allowing developers to evaluate both structured application data and visual content in the same decision workflow. Clef supports three typed question formats: noul for estimating the probability that a proposition is true, choice for selecting among predefined options and returning per-option probabilities, and score for evaluating an input against ordered criteria and producing a probability-weighted score. Applications can submit between 1 and 64 questions in a single request, with answers returned under the same question IDs.

About

Hume Audio Decisions API is a hosted API for developers building voice applications and teams evaluating speech and sound. It accepts an audio recording, optional context, and user-defined questions, then returns probabilities for answers in structured form. Questions can cover observable audio facts, such as the number of speakers or background speech, and listener judgments about tone, naturalness, empathy, clarity, or frustration. Teams can use the results to review support calls, test voice agents and text-to-speech output, label speech corpora, compare recordings, and identify examples for escalation or model training. The API works as a decision layer alongside speech recognition and voice generation, allowing application code to use its scores and probabilities in custom workflows. API access is requested through Hume, and billing is based on audio, question, and context input tokens.
