Open-source multimodal model rivaling GPT-4o on vision benchmarks
OpenGVLab/InternVL3-8Bmixpeek://image_extractor@v1/opengvlab_internvl3_8b_v1Overview
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",
{

body: JSON.stringify({

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" },

}),
},
);
// 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.Capabilities
