    Overview

    SmolVLM2 is Hugging Face's lightweight multimodal model designed for efficient video, image, and text analysis at only 2.2B parameters. Built on a SigLIP vision encoder and SmolLM2 text decoder, it processes videos natively while fitting in just 5.2 GB of GPU RAM: small enough for consumer GPUs and edge devices.

    On Mixpeek, SmolVLM2 enables cost-efficient visual captioning and understanding for high-volume video pipelines where larger VLMs would be prohibitively expensive. It scores 72.9% on OCRBench and 90% on ScienceQA, making it effective for document understanding and structured content analysis at a fraction of the compute cost of 7B+ models.

    Architecture

    SigLIP vision encoder with SmolLM2 text decoder in a Llama-style architecture. 2.2B parameters. Supports native video frame processing with temporal understanding. Only 5.2 GB GPU RAM for video inference. 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 SmolVLM2-2.2B-Instruct 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: { "multimodal-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.
