# Qwen3-4B-Instruct-2507 — RKLLM v1.2.3 (w8a8, RK3588)
RKLLM conversion of [Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507) for Rockchip RK3588 NPU inference.
Converted with RKLLM Toolkit v1.2.3. The `2507` suffix denotes the July 2025 refresh of Qwen3-4B with improved instruction following.
> **Note:** This model does **not** produce `<think>` reasoning blocks in this RKLLM build (thinking mode is disabled). See [RKLLM thinking mode limitations](https://github.com/airockchip/rknn-llm).
## Key Details
| Property | Value |
|----------|-------|
| Base Model | Qwen/Qwen3-4B-Instruct-2507 |
| Toolkit Version | RKLLM Toolkit v1.2.3 |
| Runtime Version | RKLLM Runtime ≥ v1.2.1 (v1.2.3 recommended) |
| Quantization | w8a8, group size 128 |
| Target Platform | RK3588 |
| NPU Cores | 3 |
| Max Context Length | 16384 tokens |
| Optimization Level | 1 |
| Hybrid Ratio | 0.0 |
| Thinking Mode | ❌ Disabled |
| Languages | English, Chinese (multilingual) |
## Why This Model?
Qwen3-4B-Instruct-2507 is the July 2025 update to Alibaba's Qwen3-4B, with improved reasoning and instruction following. At 4B parameters it is the largest text-only model in this RK3588 lineup and handles complex prompts well despite the quantization.
The 16k context window (vs 8k on smaller models) enables long document summarisation and multi-turn conversations.
## Hardware Tested
- **Orange Pi 5 Plus** — RK3588, 16GB RAM, Armbian Linux
- RKNPU driver 0.9.8
- RKLLM Runtime v1.2.3
## Usage
### With the RKLLM API Server
```bash
mkdir -p ~/models/Qwen3-4B-Instruct-2507
cd ~/models/Qwen3-4B-Instruct-2507
git lfs install && git clone https://huggingface.co/GatekeeperZA/Qwen3-4B-Instruct-2507-RKLLM-v1.2.3 .
```
Use with [GatekeeperZA/RKLLM-API-Server](https://github.com/GatekeeperZA/RKLLM-API-Server).
### With the official RKLLM API demo
```bash
git clone https://github.com/airockchip/rknn-llm.git
cd rknn-llm/examples/rkllm_api_demo
./build/rkllm_api_demo /path/to/Qwen3-4B-Instruct-2507-rk3588-w8a8_g128-opt-1-hybrid-ratio-0.0-16k.rkllm 8192 16384
```
