How do I call Whisper Large V3 Turbo?

Hormouz serves Whisper Large V3 Turbo on two endpoints. The OpenAI-compatible POST /v1/audio/transcriptions takes the file as the multipart field "file", or as JSON input_audio with base64 data and format, and returns {text, usage} in the same response. POST /v1/predictions handles long recordings in the background: input.audio is an https URL or a data: URI, input.language is optional. Code written for OpenAI's SDK works by changing only the base URL.

Does Whisper Large V3 Turbo handle Persian?
