🎉🎉🎉 Recently, Qihoo 360 has open sourced and upgraded its self-developed 7B parameter model 360Zhinao3-7B. It has now been launched on the Github open source community 360zhinao3 and can be used for commercial purposes free of charge. The capabilities of the model have been comprehensively improved. Compared with small parameter models with less than 10B, 360Zhinao3-7B has achieved excellent results of first place in multiple benchmarks.

360Zhinao3-7B
360Zhinao3-7B-Instruct
360Zhinao3-7B-O1.5

Notable features of our 360Zhinao3 models are:

360Zhinao3-7B is continuously pre-trained with 700B high-quality tokens on the basis of 360Zhinao2-7B. The two models have exactly the same structure. The improvement in model performance mainly stems from the improvement in the quality of training data.

Instruct Model

We have evaluated and compared the 360Zhinao3-7B-Instruct model on three popular evaluations: IFEval, MT-bench, and CF-Bench. MT-bench and CFBench both rank first among open-source models of the same level and have strong competitiveness. In IFEval (prompt strict), it is second only to glm4-9b and has the highest score in the 7B size.

Long COT Model

We used the previously open-sourced Light-R1 method of Zhinao to continue fine-tuning the Long COT of 360Zhinao3-7B-Instruct, as well as RFT and GRPO. There is still a certain gap compared with the latest OpenThinker2-7B, but it surpasses all previous models based on the general Qwen2.5-7B-Instruct.

Deployment

vLLM Installation

We recommend using vllm==0.6.0.

If you are using CUDA 12.1 and PyTorch 2.1, you can install vLLM directly with:

pip install vllm==0.6.0

Otherwise, please refer to the official vLLM Installation Instructions.

After installation, perform the following steps:

Copy vllm/zhinao.py into vllm/model_executor/models in your vllm installation directory (in python/conda env).
Then add a line in vllm/model_executor/models/__init__.py

"ZhinaoForCausalLM": ("zhinao", "ZhinaoForCausalLM"),

vLLM Service Start

Start the service:

shell

python -m vllm.entrypoints.openai.api_server \
    --model qihoo360/360Zhinao3-7B-O1.5 \
    --served-model-name 360Zhinao3-7B-O1.5 \

    --dtype bfloat16 \
    --tensor-parallel-size 4 \
    --gpu-memory-utilization 0.8 \
    --trust-remote-code

Use curl to request the service:

shell

curl http://localhost:8360/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
    "model": "360Zhinao3-7B-O1.5",

    "stop": [
        "<eod>",
        "<|im_end|>",
        "<|im_start|>"
    ]
}'

Use python to request the service:

python

from openai import OpenAI
# Set OpenAI's API key and API base to use vLLM's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://localhost:8360/v1"

client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)

chat_response = client.chat.completions.create(
    model="360Zhinao3-7B-O1.5",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "你好"},
    ],
    stop=[
        "<eod>",
        "<|im_end|>",
        "<|im_start|>"
    ],
    presence_penalty=0.0,
    frequency_penalty=0.0
)
print("Chat response:", chat_response)

If you need to enable repetition penalty, we recommend setting presence_penalty and frequency_penalty instead of repetition_penalty.
