    Overview

    Whisper is a general-purpose speech recognition model trained on a massive dataset of diverse audio. It supports multilingual transcription, translation, and language identification. The large-v3 variant achieves near-human accuracy on many benchmarks.

    On Mixpeek, Whisper powers audio transcription for video and audio content, generating timestamped text that enables full-text search across spoken content.

    Architecture

    Encoder-decoder Transformer with 32 encoder layers and 32 decoder layers. Processes 30-second audio segments as 80-channel log-mel spectrograms. Uses multi-task training format with special tokens for timestamps, language, and task type.

    Mixpeek SDK Integration

    // No extractor parameter takes a Hugging Face model id (checked against
    // GET /v1/discovery/extractors, which returns 13), so whisper-large-v3 runs
    // on your side and the output is upserted through POST
    // /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
    // path is to upload the weights instead: POST /v1/namespaces/{id}/models
    // accepts the huggingface format and a custom plugin loads them.
    const res = await fetch(
      "https://api.mixpeek.com/v1/namespaces/ns_your_namespace/documents/upsert",
      {
        method: "POST",
        headers: {
          Authorization: "Bearer API_KEY",
          "Content-Type": "application/json",
        },
        body: JSON.stringify({
          collection_id: "col_your_collection",
          documents: [
            {
              document_id: "asset-00412",
              // The model produces text, so it lands in payload. Give the
              // collection a text vector index and embed that text to make it
              // searchable rather than only filterable.
              payload: { extracted_text: modelOutput, source_key: "archive/2026/asset-00412" },
              vectors: { "text-embedding": embeddingOfModelOutput },
            },
          ],
        }),
      },
    );
    
    // Managed alternative, if this exact model is not the requirement:
    // universal_extractor@v1 runs google/gemini-embedding-2
    // (3072-d) over a bucket, with no inference of your own.
