面向开发人员的 ChatGPT 提示工程

提示指南

在本课中，您将练习两个提示原则及其相关策略，以便为大型语言模型编写有效的提示。

设置

加载 API 密钥和相关的 Python 库。

在本课程中，我们提供了一些代码来为您加载 OpenAI API 密钥。

importopenai
importos

fromdotenvimportload_dotenv,find_dotenv
_=load_dotenv(find_dotenv())

openai.api_key=os.getenv('OPENAI_API_KEY')

辅助函数

在本课程中，我们将使用 OpenAI 的 gpt-3.5-turbo 模型和聊天完成端点。

此 helper 函数将使使用提示和查看生成的输出变得更加容易。注意：2023 年 6 月，OpenAI 更新了 gpt-3.5-turbo。

您在笔记本中看到的结果可能与视频中的结果略有不同。一些提示也进行了轻微修改，以产生所需的结果。

defget_completion(prompt,model="gpt-3.5-turbo"):
messages=[{"role":"user","content":prompt}]
response=openai.ChatCompletion.create(
model=model,
messages=messages,
temperature=0,#thisisthedegreeofrandomnessofthemodel'soutput
)
returnresponse.choices[0].message["content"]

注意：本课程的此笔记本和所有其他实验笔记本都使用 OpenAI 库版本 0.27.0。

为了使用 OpenAI 库版本 1.0.0，以下是您将用于 get_completion 函数的代码：

client=openai.OpenAI()

defget_completion(prompt,model="gpt-3.5-turbo"):
messages=[{"role":"user","content":prompt}]
response=client.chat.completions.create(
model=model,
messages=messages,
temperature=0
)
returnresponse.choices[0].message.content

提示原则

原则 1：写下清晰具体的指示
原则 2：给模型时间“思考”

战术

策略 1：使用分隔符清楚地表示输入的不同部分

分隔符可以是这样的： '''， “”“， < >，，：

prompt=f"""
Summarizethetextdelimitedbytriplebackticks\
intoasinglesentence.

"""

response=get_completion(prompt)
print(response)

策略 2：请求结构化输出
