# Qwen3-VL-4B-Thinking
|
| 7 |
+
Run **Qwen3-VL-4B-Thinking** optimized for **Qualcomm NPUs** with [nexaSDK](https://sdk.nexa.ai).
|
| 8 |
+
|
| 9 |
+
## Quickstart
|
| 10 |
+
|
| 11 |
+
1. **Install NexaSDK** and create a free account at [sdk.nexa.ai](https://sdk.nexa.ai)
|
| 12 |
+
2. **Activate your device** with your access token:
|
| 13 |
+
|
| 14 |
+
```bash
|
| 15 |
+
nexa config set license '<access_token>'
|
| 16 |
+
```
|
| 17 |
+
3. Run the model on Qualcomm NPU in one line:
|
| 18 |
+
|
| 19 |
+
```bash
|
| 20 |
+
nexa infer NexaAI/Qwen3-VL-4B-Instruct-NPU
|
| 21 |
+
```
|
| 22 |
+
|
| 23 |
+
## Model Description
|
| 24 |
+
**Qwen3-VL-4B-Thinking** is a 4-billion-parameter multimodal large language model from the Qwen team at Alibaba Cloud.
|
| 25 |
+
Part of the **Qwen3-VL** (Vision-Language) family, it is designed for advanced visual reasoning and chain-of-thought generation across image, text, and video inputs.
|
| 26 |
+
|
| 27 |
+
Compared to the *Instruct* variant, the **Thinking** model emphasizes deeper multi-step reasoning, analysis, and planning. It produces detailed, structured outputs that reflect intermediate reasoning steps, making it well-suited for research, multimodal understanding, and agentic workflows.
|
| 28 |
+
|
| 29 |
+
## Features
|
| 30 |
+
- **Vision-Language Understanding**: Processes images, text, and videos for joint reasoning tasks.
|
| 31 |
+
- **Structured Thinking Mode**: Generates intermediate reasoning traces for better transparency and interpretability.
|
| 32 |
+
- **High Accuracy on Visual QA**: Performs strongly on visual question answering, chart reasoning, and document analysis benchmarks.
|
| 33 |
+
- **Multilingual Support**: Understands and responds in multiple languages.
|
| 34 |
+
- **Optimized for Efficiency**: Delivers strong performance at 4B scale for on-device or edge deployment.
|
| 35 |
+
|
| 36 |
+
## Use Cases
|
| 37 |
+
- Multimodal reasoning and visual question answering
|
| 38 |
+
- Scientific and analytical reasoning tasks involving charts, tables, and documents
|
| 39 |
+
- Step-by-step visual explanation or tutoring
|
| 40 |
+
- Research on interpretability and chain-of-thought modeling
|
| 41 |
+
- Integration into agent systems that require structured reasoning
|
| 42 |
+
|
| 43 |
+
## Inputs and Outputs
|
| 44 |
+
**Input:**
|
| 45 |
+
- Text, images, or combined multimodal prompts (e.g., image + question)
|
| 46 |
+
|
| 47 |
+
**Output:**
|
| 48 |
+
- Generated text, reasoning traces, or structured responses
|
| 49 |
+
- May include explicit thought steps or structured JSON reasoning sequences
