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

import { Mixpeek } from "mixpeek";

const mx = new Mixpeek({ apiKey: "API_KEY" });

// Managed: create a collection over a bucket; Mixpeek runs this model's extractor
const collection = await mx.collections.create({
  namespace_id: "my-namespace",
  collection_name: "my-collection",
  source: { type: "bucket", bucket_ids: ["bkt_your_bucket"] },
  feature_extractor: {
    feature_extractor_name: "scene_description",
    version: "v1",
    parameters: { model_id: "OpenGVLab/InternVL3-8B" },
  },
});
