GPT Evaluation

Table of Contents

Overview

In this directory, we introduce how you can evaluate your model using GPTs. It is now available for evaluation of both Chinese and English capability and we provide the following functions:

  • Compare the performance of two different models (battle).
  • Rate the model according to pre-defined metrics using prompting design.
  • Rate the model according to pre-defined metrics with additional reference answer using prompting design.

GPT Evaluation

Evaluation Category

Our evaluation pipeline can examine the model's capability using different categories of questions. The following table includes some example categories. You can add your own questions.

Evaluation Category Description
Brainstorming Models are asked to generate a range of creative and diverse ideas according to the question. The capability of creativity is required.
Chat Models are asked to continue a multi-round dialogue given the roles involved. The capability of understanding, memorizing previous rounds of the dialogue and answering according to the persona provided is required.
Generation Models are asked to generate an email, letter, article, etc. The capability of generating texts in a high quality and human-written way is required.
Open QA Models are asked to answer an open QA question(without context provided). The capability of answering questions with the models' own knowledge base is required.
Roleplay Models are asked to play the role provided. The capability of engaging in the scenario and effectively interacting with the user is required.

Evaluation Category Examples

To better understand each evaluation category, here are some example questions provided. Example questions are in the configs/gpt_evaluation/data folder.

Evaluation Category Chinese Example English Example

Data Format

A JSON file contains one list. Each element in the list is a target answer / prediction record for one instruction / question. An element should have the following fields:

  • category (str, compulsory): The category of the instruction / question.
  • instruction (str, compulsory): The instruction / question for the LLM.
  • input (str, optional): The additional context of the instruction / question.
  • output (str, optional): The model output of the instruction, models will fill in this field during inference time.
  • target (str, optional): The target answer for the instruction.
  • id (int, compulsory): The ID of the instruction / question.

Example:

[
    {
        "category": "brainstorming",
        "instruction": "请问如何制作一份美味的西红柿炒鸡蛋？",
        "input": "",
        "output": "",
        "target": "",
        "id": 1
    },
    {
        "category": "chat",
        "instruction": "基于以下角色信息完成一段对话。小张是一名新手爱好者，对养鸡有浓厚的兴趣。老李是一名有丰富经验的养鸡大师。",
        "input": "小张：您好，老李，我最近开始对养鸡感兴趣了，想请教您一些问题。 老李：你好，小张，我很乐意帮助你。你想问些什么？ 小张：我想知道如何确定鸡的品种和性别？ 老李：确切的品种可以通过鸡的外貌特征来确定，而性别一般是通过鸡卵的大小和形状来判断。还有什么问题吗？ 小张：",
        "output": "",
        "target": "",
        "id": 2
    }
]

Prompt

Battle Prompt

The following is the Chinese battle prompt. In the battle prompt, the question and answers from two different models are fed into the prompt template. You can find example battle prompt files for Chinese and English in configs/gpt_evaluation/prompt/battle_prompt.

{
  "id": 1,
  "system_prompt": "你是一个检查回答质量的好助手。",
  "prompt_template": "[问题]\n{question}\n\n[1号AI助手的答案]\n{answer_1}\n\n[1号AI助手答案终止]\n\n[2号AI助手的答  案]\n{answer_2}\n\n[2号AI助手答案终止]\n\n[要求]\n{prompt}\n\n",
  "prompt": "我们需要你评价这两个AI助手回答的性能。\n请对他们的回答的有用性、相关性、准确性、详细程度进行评分。每个AI助手都会得到一个1到10分的总分，分数越高表示整体表现越好。\n请首先输出一行，该行只包含两个数值，分别表示1号和2号AI助手的分数。这两个分数之间要有一个空格。在随后的一行中，请对你的评价作出全面的解释，避免任何潜在的偏见，并确保AI助手回答的顺序不会影响您的判断。"
}

Evaluation Prompt

The following is an example of a Chinese GPT evaluation prompt. In an evaluation prompt, you should define your metrics in metrics and provide CoT(Chain-of-Thought) in CoT. You can find example evaluation prompt files for Chinese and English in configs/gpt_evaluation/prompt/evaluation_prompt.

{
  "brainstorming": {
    "id": 1,
    "category": "brainstorming",
    "metrics": {
      "language organization": "语言组织(1-5)：答案语言是否流畅、连贯，使用正确的语法，具有一定逻辑性，使用恰当的连接词、过渡词等等。"
    },
    "CoT": {
      "language organization": "1. 阅读答案，并检查是否有语法错误、用词不当或其他显著的错误。\n2. 检查答案是否具有逻辑性，能够按照合理的顺序传达信息并且能够自圆其说。\n3. 确定答案是否与问题或主题相关，并且能够传达清晰的信息。\n4. 检查答案是否连贯，是否使用适当的转换和过渡来保持句子和段落之间的连贯性。\n5. 检查答案是否具有明确的结构和组织方式，使得读者可以轻松理解信息的层次和结构。\n6. 根据以上因素综合评估答案的语言组织，并给出一个1到5的分数，其中5表示语言组织非常好，而1表示语言组织非常差。\n\n语言组织："
    },
    "prompt": "你是一个好助手。请你为下面“头脑风暴”问题的答案打分。\n\n问题如下：\n\n{question}\n\n答案如下：\n\n{answer}\n\n评分的指标如下：\n\n{metric}\n\n请你遵照以下的评分步骤：\n\n{steps}"
  }
}

"metrics": the metrics that can be used in GPT evaluation. This field determines which metrics can be added to your config file.

"CoT": evaluation steps you prompt to GPT models for each metric defined in "metrics".

Evaluation

Configuration

The following is an example of a Chinese config file. The configuration file can control how the pipeline evaluates the model. You need to specify GPT evaluation metrics in key GPT. You can find an example English config file in configs/gpt_evaluation/config/config_en.json.

{
    "language": "cn",
    "category": {
        "brainstorming": {
            "GPT": [
                "language organization",
                "relevance",
                "creativity",
                "practicality",
                "reasonableness"
            ]
        }
    }
}

"language": the language used to evaluate the model capability. We only support Chinese "cn" for now.

"category": the category/categories needed to evaluate the model capability.

"GPT": the metrics you want to use for GPT evaluation.

Evaluate

After setting the configuration file, you can evaluate the model using examples/gpt_evaluation/eval.py. If you want to make comparisons between answers of two different models, you should specify two answer files in the argument answer_file_list and two model names in the argument model_name_list. If you want to evaluate one answer file, the length of both answer_file_list and model_name_list should be 1 and the program will perform evaluation using automatic metrics and GPT models.

An example script is provided as follows:

python eval.py \
    --config_file "path to the config file" \
    --battle_prompt_file "path to the prompt file for battle" \
    --gpt_evaluation_prompt_file "path to the prompt file for gpt evaluation" \
    --target_file "path to the target answer file" \
    --answer_file_list "path to the answer files of at most 2 models" \
    --model_name_list "the names of at most 2 models" \
    --gpt_model "which GPT model to use for evaluation" \
    --save_path "path to save results" \
    --openai_key "your openai key" \

If you want GPT evaluation with reference, you can add an argument --gpt_with_reference, but make sure the reference file have target answers.

FAQ

How can I add a new GPT evaluation metric?

For example, if you want to add a new metric persuasiveness into category brainstorming, you should add the metric definition and its corresponding CoT(Chain-of-thought) in the evaluation prompt file in prompt/evaluation_promt. The CoT can be generated using ChatGPT. You can prompt ChatGPT to generate evaluation steps for the new metric.

{
  "brainstorming": {
    "id": 1,
    "category": "brainstorming",
    "metrics": {
      "persuasiveness": "persuasiveness(1-5)：a short description for persuasiveness"
    },
    "CoT": {
      "persuasiveness": "CoT for persuasiveness\n\npersuasiveness："
    },
    "prompt": "You are a good assistant. Please rate the given answer to the \"brainstorming\" question below.\n\nThe question is as follows:\n\n{question}\n\nThe answer is as follows:\n\n{answer}\n\nThe metric for evaluation is as follows:\n\n{metric}\n\nYou should follow the following evaluation steps:\n\n{steps}"
  }
