Overview

Qwen3-VL-4B-Instruct is a dense 4.4B-parameter vision-language model with a three-module architecture: vision encoder, MLP-based vision-language merger, and LLM decoder. It supports 256K-1M context, 32-language OCR, native video temporal reasoning, and strong document understanding with 95.3% on DocVQA and 88.1% on OCRBench.

On Mixpeek, Qwen3-VL-4B powers scene captioning, visual question answering, and document understanding at the 4B parameter sweet spot, offering the best quality-to-cost ratio for pipelines that need both visual and text comprehension.

Architecture

Dense transformer (36 layers, GQA 32/8) with 4.44B parameters. Three-module design: vision encoder, MLP vision-language merger, and LLM decoder. Interleaved-MRoPE for video temporal reasoning, DeepStack for multi-level ViT feature fusion, and Text-Timestamp Alignment for event localization.

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_caption",
    version: "v1",
    parameters: { model_id: "Qwen/Qwen3-VL-4B-Instruct" },
  },
});
