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:

pip install torch==2.7.0 torchvision==0.22.0 

Then you should install our vLLM wheel package:

pip install https://media.githubusercontent.com/media/inclusionAI/Ring-V2/refs/heads/main/hybrid_linear/whls/vllm-0.8.5%2Bcuda12_8_gcc10_2_1-cp310-cp310-linux_x86_64.whl --no-deps --force-reinstall

Offline Inference

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

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)


llm = LLM(model="inclusionAI/Ring-flash-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)

Online Inference

vllm serve inclusionAI/Ring-mini-linear-2.0-GPTQ-int4 \
              --tensor-parallel-size 2 \
              --pipeline-parallel-size 1 \

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.
