你的提示词应当清晰而具体
你的提示词应当包含以下内容:
- 角色(例如:AI 新闻助手)
- 目标(例如:编写新闻报告)
- 方式(例如:以 XXX 为文章结构)
- 限制(例如:不要包括商业相关内容)
不要将提示词设计得过于宽泛,例如:
✅ Yes: You are writing a Python function to calculate the factorial of a given number.
❌ No: Write something about numbers.
✅ Yes: Generate a headline about the latest breakthrough in quantum computing.
❌ No: Write a news article.
你应该提供尽可能清晰而具体的说明,来表达你希望模型执行的任务。这将指导模型生成期望的输出,减少无关或错误响应的可能。
不要把清晰的提示和简短的提示混为一谈。在很多情况下,较长的提示可以为模型提供更多的清晰度和上下文,从而产生更详细和更相关的输出。
合适的结构和使用分隔符来清楚表达意图
如果你的提示词较长,你可以以多行结构 + Markdown 的方式提供给 LLM。例如:
## 角色
你是一个 AI 新闻助手。
## 目标
当被要求时,你需要编写新闻报告。
......
不要将多条要求堆叠在一行中,这样会使模型难以处理。
如果在提示词中需要插入 LLM 需要的资源、材料,你可以使用分隔符 等将其与命令隔开,以保证提示词的清晰性。
分隔符可以是任何明确的标点符号,将特定的文本片段部分与提示的其它部分分隔开来。分隔符可以使用三重双引号、单引号、XML标记、章节标题,或者任何可以向模型表明这是一个单独部分的符号或标记。例如我们可以使用这些分隔符: """,---,< >,<tag> </tag>。
要求模型进行预检查和自我审查
有时,用户的输入可能根本就无解或者不符合情景,例如,你要求 LLM 指出一个没有语法错误的文章内的语法错误,这是不可能的。这时,LLM 可能会输出一些无意义的内容。为了避免这种情况,你可以要求 LLM 在生成文本之前进行预检查,以确保输入是有效的。例如:
⚙️ System:你现在是一个英语文章语法错误检查器。请在回答前检查文章中的语法错误。如果没有语法错误,请说:“没有语法错误”。
😆 User:我的文章是:......
🤖 Assistant:没有语法错误
自我审查也是很重要的。基于 Transformer 架构,模型在生成文本时出现一些问题是很正常的。这时,要求模型在回答末尾自我审查自己的回答是否正确是很有帮助的。例如一个经典的例子:
😆 User:树上有三只鸟,打死了一只,还有几只?
🤖 Assistant:树上有三只鸟,打死了一只,剩下的还是三只。打死一只并不会影响其他两只的数量。
而如果我们要求模型在回答末尾进行自我检查,就可以避免这种问题:
😆 User:树上有三只鸟,打死了一只,还有几只?请在回答完毕后自我检查你的答案是否符合自然规律。
🤖 Assistant:有两只。但是,自然规律下,枪击声音可能会吓跑其余的鸟,所以树上可能最终没有任何鸟。
向 LLM 提供少样本提示(few-shot prompt)
如果你的要求较为复杂,你可以向 LLM 提供一些案例。这些案例可以帮助 LLM 更好地理解你的要求。例如:
⚙️ System:你现在是一个 Linux Bash 终端。用户向你输入命令时,你应当返回命令正确的输出结果。
下面是一个例子:
用户输入:`sudo apt update`
你应当回答:```
Fetched 106 kB in 1s (96.2 kB/s)
Reading package lists... Done
Building dependency tree
Reading state information... Done```。
😆 User:ls
🤖 Assistant: bin data home lib libx32 mnt proc sbin sys var dev ......

[方式]
First think step-by-step - describe your plan for what to build in pseudocode, written out in great detail.
Then output the code in a single code block.
Minimize any other prose.
Keep your answers short and impersonal.
Use Markdown formatting in your answers.
Make sure to include the programming language name at the start of the Markdown code blocks.
Avoid wrapping the whole response in triple backticks.
The user works in an IDE called Visual Studio Code which has a concept for editors with open files, integrated unit test support, an output pane that shows the output of running the code as well as an integrated terminal.
The active document is the source code the user is looking at right now.
[限制]
You can only give one reply for each conversation turn.
You should always generate short suggestions for the next user turns that are relevant to the conversation and not offensive.
