Prompt Engineering - 提示工程

生成式 AI 應用程式傳回的回應品質不僅取決於模型本身，也取決於其所提供的提示類型。 「提示工程」一詞描述提示改善的流程。 設計應用程式的開發人員和使用這些應用程式的取用者，都可以考慮使用提示工程來改善生成式 AI 的回應品質。

提示是我們告知應用程式預期執行操作的方式。 工程師可以利用提示來新增程式的指示。 例如，開發人員可以為教師建置生成式 AI 應用程式，以建立與學生閱讀文字相關的複選問題。 在應用程式開發期間，開發人員可以新增其他規則，定義程式應該根據收到的提示執行哪些操作。

為什麼要使用英文 prompt 而不使用中文提問?

  1. 英文的訓練語料庫占比超過93%，中文約0.04%，使用英文提問時，它能返回更準確的解答。
  2. ChatGPT在一次輸入中，最多處理4096 token——超過上限的任何字符都將被忽略而不會顯示訊息。相較之下，英文的token使用量少，使用英文提問時，它能給予更多篇幅的答案(中文消耗的token約是英文兩倍)。詳細的可參考OpenAI token解答，以及使用官方的token計算器
  3. 返回英文答案後，再使用ChatGPT翻譯成中文就行了。例如：Please write in Traditional Chinese language.

Instruct

# Prompt
You are an expert programmer that writes simple, concise code and explanations. Write a python function to generate the nth fibonacci number.

Response:

Here is a Python function that generates the nth Fibonacci number:

def fib(n):
    if n <= 1:
        return n
    else:
        return fib(n-1) + fib(n-2)

This function uses the recursive formula for the Fibonacci sequence, which is:

fib(n) = fib(n-1) + fib(n-2)

Code Review

# Prompt
Where is the bug in this code?

def fib(n):
    if n <= 0:
        return n
    else:
        return fib(n-1) + fib(n-2)

Response:

The bug in this code is that it does not handle the case where `n` is equal to 1.

Unit Tests

# Prompt
write a unit test for this function: $(cat fib.py)

Response:

Here's an example of how you could write a unit test for the `fib` function:

```
import unittest

class TestFib(unittest.TestCase):
    def test_fib(self):
        self.assertEqual(fib(0), 0)
        self.assertEqual(fib(1), 1)
        self.assertEqual(fib(2), 1)
        self.assertEqual(fib(3), 2)
        self.assertEqual(fib(4), 3)
        self.assertEqual(fib(5), 5)
        self.assertEqual(fib(6), 8)
        self.assertEqual(fib(7), 13)
        self.assertEqual(fib(8), 21)
        self.assertEqual(fib(9), 34)
if __name__ == '__main__':
    unittest.main()
```

This test case covers all the cases where the input is an integer between 0 and 9, inclusive.

Code Completion

# Prompt
# A simple python function to remove whitespace from a string:

Response:

def remove_whitespace(s):
    return ''.join(s.split())

Infill: <PRE> {prefix} <SUF>{suffix} <MID>

# Prompt
<PRE> def compute_gcd(x, y): <SUF>return result <MID>

Response:

  if x == y:
        return x

    if x > y:
        x = x - y
    else:
        y = y - x

    result = compute_gcd(x, y)
