2 prompt工程2大原则

2.1 给出清晰，详细的指令
策略1：使用分割符清晰的指示输出的不同部分，比如"",<>,<\tag>等分隔符

策略2：指定一个结构化的输出，比如json,html等格式

策略3：要求模型自检测是否满足条件

策略4：提供少量示例（few-shot)

2.2 给模型思考的时间 (CoT)
我们不一定要一步得到答案，可以让模型进行一系列的推理，给他推理思考的时间，再最终给出答案。

策略1：指定完成任务需要的步骤

告诉模型完成这个指令，需要执行几步，每步的详细步骤

策略2：明确模型再给出结论之前推理出自己的解决方案

让模型自己推理，写出每一步的步骤，给足够的时间（token-钱）边思考边执行。

3. 迭代式优化

4. CoT

4.1，思维链允许模型将多步问题进行拆分，分解为多个中间步骤。

4.2，思维链使得模型的回答过程具有较好的可解释性，同时这一特性为定位推理错误，并修改错误提供了可能。

4.3，链式思维推理可用于数学单词问题、常识推理和符号操作等任务，并且理论上适用于任何可以通过语言解决的任务。

4.4，CoT+Few-shot，效果更好。

6. 用大模型来写prompt:

message = [
            {"content": """
            I want you to act as an AI prompt engineer. You are expert at writing ChatGPT Prompts to get the best results.

            To create efficient prompts that yield high-quality responses, consider the following principles and strategies: \
            1. Clear and Specific: Be as clear and specific as possible about what you want from the AI. If you want a certain type of response, outline that in your prompt. If there are specific constraints or requirements, make sure to include those as well.
            2. Open-ended vs. Closed-ended: Depending on what you're seeking, you might choose to ask an open-ended question (which allows for a wide range of responses) or a closed-ended question (which narrows down the possible responses). Both have their uses, so choose according to your needs.
            3. Contextual Clarity: Make sure to provide enough context so that the AI can generate a meaningful and relevant response. If the prompt is based on prior information, ensure that this is included.
            4. Creativity and Imagination: If you want creative output, encourage the AI to think outside the box or to brainstorm. You can even suggest the AI to imagine certain scenarios if it fits your needs.

            There is a well-written prompt delimited by <> for your reference: <Your task is to be my brainstorming partner and provide creative ideas and suggestions for a given topic or problem. Your response should include original, unique, and relevant ideas that could help solve the problem or further explore the topic in an interesting way. Please note that your response should also take into account any specific requirements or constraints of the task.>

            Your task is to write an effective ChatGPT Prompt based on given keywords or to modify the given prompts. Answer in the same language as me.
            """,
            "role": "system"}
        ]

message.append(
            {"content": "Please help me to write an effective ChatGPT Prompt based on the following keywords or prompt: {}".format(prompt),
             "role": "user"}
        )

7. "要想写好prompt最好的方法就是知道他的训练数据是什么样子的。"

8. 例子

从上面看到，规律是：他是什么角色+让他干什么

你是一位擅长编写各种程序的资深工程师，我需要你根据以下需求，为我生成一段Python代码：
