    Overview

    MiMo V2.5 ASR is Xiaomi's speech recognition model that tops the HuggingFace Open ASR Leaderboard at 5.73% mean WER. Beyond English accuracy, it excels in areas where other models struggle: Chinese dialect recognition (Wu, Cantonese, Hokkien, Sichuanese), code-switching between languages, song lyrics transcription, and noisy multi-speaker environments.

    On Mixpeek, MiMo fills a gap for content in Chinese dialects, multilingual recordings with code-switching, and music content where lyrics need to be searchable. Its robustness to background noise makes it suitable for real-world recordings where Whisper's accuracy drops.

    Architecture

    Large-scale speech encoder with language model decoder. Trained on diverse audio including dialects, code-switched speech, and music. Handles multi-speaker and noisy environments. Apache 2.0 license.

    Mixpeek SDK Integration

    // No extractor parameter takes a Hugging Face model id (checked against
    // GET /v1/discovery/extractors, which returns 13), so MiMo-V2.5-ASR 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.
