Llama-3.2-3B-Instruct_w8a8_g128_rk3588.rkllm

Llama-3.2-3B-Instruct — RKLLM build for RK3588 boards

Built with Llama 3.2 (Meta Platforms, Inc.)

Author: @jamescallander
Source model: meta-llama/Llama-3.2-3B-Instruct · Hugging Face

Target: Rockchip RK3588 NPU via RKNN-LLM Runtime

This repository hosts a conversion of Llama-3.2-3B-Instruct for use on Rockchip RK3588 single-board computers (Orange Pi 5 plus, Radxa Rock 5b+, Banana Pi M7, etc.). Conversion was performed using the RKNN-LLM toolkit

Conversion details

• RKLLM-Toolkit version: v1.2.1
• NPU driver: v0.9.8
• Python: 3.12
• Quantization: w8a8_g128
• Output: single-file .rkllm artifact
• Modifications: quantization (w8a8_g128), export to .rkllm format for RK3588 SBCs
• Tokenizer: not required at runtime (UI handles prompt I/O)

Intended use

• On-device chat and instruction following on RK3588 SBCs.
• Llama-3.2-3B-Instruct is tuned for general conversational tasks, Q&A, and reasoning, making it suitable for edge inference deployments where low power and privacy matter.

Limitations

• Requires 4GB free memory
• Quantized build (w8a8_g128) may show small quality differences vs. full-precision upstream.
• Tested on a Radxa Rock 5B+; other devices may require different drivers/toolkit versions.

Quick start (RK3588)

1) Install runtime

The RKNN-LLM toolkit and instructions can be found on the specific development board's manufacturer website or from airockchip's github page.

Download and install the required packages as per the toolkit's instructions.

2) Simple Flask server deployment

The simplest way the deploy the .rkllm converted model is using an example script provided in the toolkit in this directory: rknn-llm/examples/rkllm_server_demo

python3 <TOOLKIT_PATH>/rknn-llm/examples/rkllm_server_demo/flask_server.py \
  --rkllm_model_path <MODEL_PATH>/Llama-3.2-3B-Instruct_w8a8_g128_rk3588.rkllm \
  --target_platform rk3588

3) Sending a request

A basic format for message request is:

{
    "model":"Llama-3.2-3B",
    "messages":[{
        "role":"user",
        "content":"<YOUR_PROMPT_HERE>"}],
    "stream":false
}

Example request using curl:

curl -s -X POST <SERVER_IP_ADDRESS>:8080/rkllm_chat \
    -H 'Content-Type: application/json' \
    -d '{"model":"Llama-3.2-3B","messages":[{"role":"user","content":"Explain who Napoleon Bonaparte is in two or three sentences."}],"stream":false}'

The response is formated in the following way:

{
    "choices":[{
        "finish_reason":"stop",
        "index":0,
        "logprobs":null,
        "message":{
            "content":"<MODEL_REPLY_HERE">,
            "role":"assistant"}}],
        "created":null,
        "id":"rkllm_chat",
        "object":"rkllm_chat",
        "usage":{
            "completion_tokens":null,
            "prompt_tokens":null,
            "total_tokens":null}
}

Example response:

{"choices":[{"finish_reason":"stop","index":0,"logprobs":null,"message":{"content":"Napoleon Bonaparte was a French military leader and statesman who rose to power during the French Revolution, becoming Emperor of France from 1804 to 1815. He is known for his military conquests, strategic genius, and domestic reforms that transformed Europe, but his ambition and authoritarian rule ultimately led to his downfall. His legacy has been debated among historians, with some viewing him as a brilliant leader who modernized France, while others see him as a power-hungry dictator responsible for devastating wars and loss of life.","role":"assistant"}}],"created":null,"id":"rkllm_chat","object":"rkllm_chat","usage":{"completion_tokens":null,"prompt_tokens":null,"total_tokens":null}}
