    Overview

    Whisper Large V3 Turbo is OpenAI's speed-optimized variant of Whisper Large V3, achieved by pruning the decoder from 32 layers to 4. This yields a 216x real-time speed factor with less than 1% increase in word error rate compared to the full model.

    The model retains the full encoder and multilingual capabilities of Whisper Large V3, supporting 100+ languages. On Mixpeek, it provides the best speed/quality tradeoff for production ASR workloads -- fast enough for batch processing of large video libraries while maintaining near-full accuracy.

    Architecture

    Encoder-decoder Transformer. Full Whisper Large V3 encoder (32 layers) with pruned decoder (4 layers, down from 32). 809M total parameters. 128 mel spectrogram input. Multilingual, multitask (transcription + translation).

    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-turbo 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.
