    Overview

    InternVL3-8B is an open-source vision-language model from the InternVL family that follows the ViT-MLP-LLM paradigm, combining an InternViT vision encoder with a language model backbone via an MLP projector. It achieves remarkable performance that exceeds GPT-4o on several benchmarks including MMMU (72.2 vs 70.7) while being fully open-source.

    On Mixpeek, InternVL3-8B is a top-tier open-source option for visual understanding that delivers near-proprietary-model quality for scene captioning, visual reasoning, document analysis, and scientific image understanding.

    Architecture

    ViT-MLP-LLM architecture with InternViT vision encoder connected to a Qwen2.5/InternLM3-8B language model via a randomly initialized MLP projector. Features Variable Visual Position Encoding, Native Multimodal Pre-Training, and Mixed Preference Optimization for enhanced multimodal reasoning.

    Mixpeek SDK Integration

    // No extractor parameter takes a Hugging Face model id (checked against
    // GET /v1/discovery/extractors, which returns 13), so InternVL3-8B 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.
