How do I call Nemotron 3.5 ASR Streaming Multilingual 0.6B?

Hormouz serves Nemotron 3.5 ASR Streaming Multilingual 0.6B 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.

Hormouz serves Nemotron 3.5 ASR Streaming Multilingual 0.6B on two endpoints: the OpenAI-compatible /v1/audio/transcriptions, which returns the text in the same response, and /v1/predictions for long recordings processed in the background. It is not suitable for Persian: in our tests it did not produce a usable Persian transcript. For Persian, choose a model that did well in our tests, such as Scribe v2, MAI-Transcribe 2 or Whisper Large V3.
