Technical Background and Evaluation Motivation

Recent advancements in Chinese large language models have seen rapid iterations, with notable releases including Platform X’s V4 Pro and GLM-5.3 from a leading research team. These models demonstrate distinct characteristics: GLM-5.3 maintains 743B parameters with 50% performance improvement through post-training optimization, while Platform X V4 Pro adopts Mixture of Experts (MoE) architecture showing breakthroughs in long-context processing.

The industry faces critical challenges due to fragmented evaluation systems. Models optimized within proprietary toolchains often show inconsistent performance when deployed elsewhere. For example, a model achieving 85% accuracy in one framework may drop to 60% in another environment, primarily due to differences in inference engine optimizations and operator implementations.

Our solution proposes a unified evaluation framework that ensures:

1. Consistent input preprocessing pipelines
2. Equal computational resource allocation
3. Standardized output post-processing
4. Comparable performance metric collection

Evaluation Framework Implementation

2.1 Environment Configuration

We recommend using a 4xA100 GPU server with CUDA 11.8 and PyTorch 2.0. Docker containerization is advised for environment isolation, with this base image configuration:

FROM nvidia/cuda:11.8.0-base-ubuntu22.04
RUN apt-get update && apt-get install -y \
    python3.10 \
    python3-pip \
    && rm -rf /var/lib/apt/lists/*
RUN pip install torch==2.0.1 transformers==4.30.2

2.2 Model Integration Architecture

The framework uses a three-layer architecture:

1. Model Adapter Layer: Implements standardized predict() interface
2. Resource Scheduler: Dynamically allocates GPU memory and compute resources
3. Metric Collector: Records inference latency, throughput, and accuracy

Key integration example:

class ModelAdapter:
    def __init__(self, config):
        self.provider = config['provider']
        self.api_key = config['api_key']
        self.model_name = config['model_name']
    def predict(self, prompt):
        if self.provider == 'zai-coding':
            return self._call_glm_api(prompt)
        elif self.provider == 'platform-x':
            return self._call_platform_api(prompt)
    def _call_glm_api(self, prompt):
        headers = {'Authorization': f'Bearer {self.api_key}'}
        payload = {
            'model': self.model_name,
            'prompt': prompt,
            'max_tokens': 2048
        }
        response = requests.post(
            'https://api.zai-coding.cn/v1/chat/completions',
            headers=headers,
            json=payload
        )
        return response.json()['choices'][0]['message']['content']

2.3 Benchmark Dataset Construction

We use the GSM8K mathematical reasoning dataset (8.5K elementary-level word problems) with these preprocessing steps:

1. JSON format standardization
2. Difficulty grading (1-5 levels)
3. Random question shuffling
4. 81 train/validation/test split

Sample data structure:

{
  "id": "GSM8K_1234",
  "grade": 3,
  "question": "Xiaoming has 5 apples and eats 2...",
  "options": ["A. 2", "B. 3", "C. 4", "D. 5"],
  "solution": "B"
}
