【使用LLM搭建系统】5 处理输入: 链式 Prompt Chaining Prompts

杨过过儿2025-06-10 19:14

本章内容主要介绍了将复杂任务拆分为多个子任务（链式Prompt）的方法及其优势。尽管高级语言模型像GPT - 4擅长一次性遵循复杂指令，但有时拆分任务更可取。通过两个比喻来阐述原因：

  1. 一次烹饪复杂菜肴与分阶段烹饪：一次性复杂Prompt像一次性烹饪复杂菜肴，易出错；链式Prompt像分阶段烹饪，逐步确保每个部分正确。

  2. 一次性完成任务与分阶段完成任务：复杂单步任务像一长串代码，难调试；而链式Prompt如同模块化程序，当有需要在各节点根据状态调整操作的工作流程时，能提高效率。

一、环境设置

python 复制代码 
from zhipuai import ZhipuAI
# 导入第三方库

key = "f5cd91f2528fed334b9dfd75015791c3.GuLdvM9tXWrGQnAg"
client = ZhipuAI(api_key = key)
python 复制代码 
def get_completion_from_messages(messages, 
                                model="glm-3-turbo", 
                                temperature=0, 
                                max_tokens=500):
    '''
    封装一个访问 OpenAI GPT3.5 的函数

    参数: 
    messages: 这是一个消息列表，每个消息都是一个字典，包含 role(角色）和 content(内容)。角色可以是'system'、'user' 或 'assistant'，内容是角色的消息。
    model: 调用的模型，默认为 gpt-3.5-turbo(ChatGPT)，有内测资格的用户可以选择 gpt-4
    temperature: 这决定模型输出的随机程度，默认为0，表示输出将非常确定。增加温度会使输出更随机。
    max_tokens: 这决定模型输出的最大的 token 数。
    '''
    response = client.chat.completions.create(
        model=model,
        messages=messages,
        temperature=temperature, # 这决定模型输出的随机程度
        max_tokens=max_tokens, # 这决定模型输出的最大的 token 数
    )
    return response.choices[0].message.content

二、 实现一个包含多个提示的复杂任务

2.1 提取相关产品和类别名称

对客户查询进行分类后，采用链式Prompt方法的优势：

  1. 任务明确与管理简便：每个子任务只包含必要指令，使系统易于管理，确保模型具备执行任务所需信息，降低出错率。

  2. 降低成本：避免使用过长的Prompt和过多的tokens，减少运行成本，且在某些情况下无需概述所有步骤。

  3. 便于测试与干预：更容易测试哪些步骤可能失败，或在特定步骤中需要人工干预。

  4. 培养策略运用直觉：随着与模型的深入交互，逐渐形成何时使用该策略的直觉。

  5. 支持外部工具调用：允许模型在必要时调用外部工具，如在产品目录中查找内容、调用API或搜索知识库，这是单个Prompt无法实现的。

python 复制代码 
delimiter = "####"
system_message = f"""
你将提供服务查询。
服务查询将使用{delimiter}字符分隔。

仅输出一个 Python 对象列表，其中每个对象具有以下格式：
    'category': <计算机和笔记本电脑、智能手机和配件、电视和家庭影院系统、游戏机和配件、音频设备、相机和摄像机中的一个>,
或者
    'products': <必须在下面的允许产品列表中找到的产品列表>

类别和产品必须在客户服务查询中找到。
如果提及了产品，则必须将其与允许产品列表中的正确类别相关联。
如果未找到产品或类别，则输出空列表。

允许的产品：

计算机和笔记本电脑类别：
TechPro Ultrabook
BlueWave Gaming Laptop
PowerLite Convertible
TechPro Desktop
BlueWave Chromebook

智能手机和配件类别：
SmartX ProPhone
MobiTech PowerCase
SmartX MiniPhone
MobiTech Wireless Charger
SmartX EarBuds

电视和家庭影院系统类别：
CineView 4K TV
SoundMax Home Theater
CineView 8K TV
SoundMax Soundbar
CineView OLED TV
c
游戏机和配件类别：
GameSphere X
ProGamer Controller
GameSphere Y
ProGamer Racing Wheel
GameSphere VR Headset

音频设备类别：
AudioPhonic Noise-Canceling Headphones
WaveSound Bluetooth Speaker
AudioPhonic True Wireless Earbuds
WaveSound Soundbar
AudioPhonic Turntable

相机和摄像机类别：
FotoSnap DSLR Camera
ActionCam 4K
FotoSnap Mirrorless Camera
ZoomMaster Camcorder
FotoSnap Instant Camera

仅输出 Python 对象列表，不包含其他字符信息。
"""
user_message_1 = f"""
 请查询 SmartX ProPhone 智能手机和 FotoSnap 相机，包括单反相机。
 另外，请查询关于电视产品的信息。 """
messages =  [  
{'role':'system', 
 'content': system_message},    
{'role':'user', 
 'content': f"{delimiter}{user_message_1}{delimiter}"},  
] 
category_and_product_response_1 = get_completion_from_messages(messages)
print(category_and_product_response_1)
复制代码 
[
    {'products': ['SmartX ProPhone']},
    {'category': '智能手机和配件'},
    {'products': ['FotoSnap DSLR Camera']},
    {'category': '相机和摄像机'},
    {'category': '电视和家庭影院系统'}
]

输出是一个对象列表，每个对象包含一个类别和一些产品，例如"SmartX ProPhone"和"Fotosnap DSLR Camera"。在某些情况下，可能只有一个类别而没有具体的产品，例如最后一个对象中没有提到任何具体的电视。这种结构化的输出可以轻松地读入Python的列表中，便于后续处理。

python 复制代码 
user_message_2 = f"""我的路由器坏了"""
messages =  [  
{'role':'system',
 'content': system_message},    
{'role':'user',
 'content': f"{delimiter}{user_message_2}{delimiter}"},  
] 
response = get_completion_from_messages(messages)
print(response)

没有包含任何路由器的信息，输出是一个空列表。

2.2 检索提取的产品和类别的详细信息

提供大量的产品信息作为示例，要求模型提取产品和对应的详细信息

python 复制代码 
def get_product_by_name(name):
    """
    根据产品名称获取产品

    参数:
    name: 产品名称
    """
    return products.get(name, None)

def get_products_by_category(category):
    """
    根据类别获取产品

    参数:
    category: 产品类别
    """
    return [product for product in products.values() if product["category"] == category]
python 复制代码
