Quantized Ring-Linear-2.0

Introduction

To enable deployment of Ring-Linear-2.0 on memory-constrained devices, we release quantized weights using the GPTQ INT4 format. Additionally, we evaluate the online FP8 quantization performance of Ring-Linear-2.0 models, which closely approaches that of BF16 precision.

Quickstart

🚀 vLLM

Environment Preparation

Since the Pull Request (PR) has not been submitted to the vLLM community at this stage, please prepare the environment by following the steps below.

First, create a Conda environment with Python 3.10 and CUDA 12.8:

shell

conda create -n vllm python=3.10
conda activate vllm

Next, install our vLLM wheel package:

shell

pip install https://media.githubusercontent.com/media/zheyishine/vllm_whl/refs/heads/main/vllm-0.8.5.post2.dev28%2Bgd327eed71.cu128-cp310-cp310-linux_x86_64.whl --force-reinstall

Finally, install compatible versions of transformers after vLLM is installed:

shell

pip install transformers==4.51.1

Offline Inference

python

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

if __name__ == '__main__':
    tokenizer = AutoTokenizer.from_pretrained("inclusionAI/Ring-mini-linear-2.0-GPTQ-int4")
    
    sampling_params = SamplingParams(temperature=0.6, top_p=1.0, max_tokens=16384)

    # use `max_num_seqs=1` without concurrency
    llm = LLM(model="inclusionAI/Ring-mini-linear-2.0-GPTQ-int4", dtype='auto', enable_prefix_caching=False, max_num_seqs=128)
    
    
    prompt = "Give me a short introduction to large language models."
    messages = [
        {"role": "user", "content": prompt}
    ]
    
    text = tokenizer.apply_chat_template(
        messages,
        tokenize=False,
        add_generation_prompt=True
    )
    outputs = llm.generate([text], sampling_params)
    for output in outputs:
        print(output.outputs[0].text)

Online Inference

shell

vllm serve inclusionAI/Ring-mini-linear-2.0-GPTQ-int4 \
              --tensor-parallel-size 1 \
              --pipeline-parallel-size 1 \
              --gpu-memory-utilization 0.90 \
              --max-num-seqs 128 \
              --no-enable-prefix-caching
              --api-key your-api-key

Evaluation

We evaluate the INT4 and FP8 quantized models using several datasets. The FP8 quantization is applied via the quantization="fp8" argument in SGLang or vLLM.
