1、GPT賦能軟件研發：能力、局限與落地實踐李明宇中科院計算所高級工程師，20年編程老師傅目錄CONTENTS軟件研發過程與大語言模型01 代碼生成與實踐案例02 代碼審查與實踐案例03 數據結構化與質量提升04 軟件研發過程與大語言模型各種場合常見演示例子：1.個人主頁，特點：html+css+少量js=語法錯誤不妨礙結果展現，通過率高，好上手2.解算法題，特點：經典題為主，看起來驚艷，但不排除“背答案”3.俄羅斯方塊、貪吃蛇 ，特點：同上實際生產中表現如何？兩類觀點：vs軟件研發過程與大語言模型不僅僅是生成業務代碼：需求分析、代碼生成、自動化測試、代碼審查、線上運維調試 不僅僅提高效率，同時要

2、提高質量不僅僅是chat，還有API調用：curl https:/ Content-Type:application/json-H Authorization:Bearer$OPENAI_API_KEY-d model:gpt-3.5-turbo,messages:role:system,content:Test,role:user,content:,temperature:1,max_tokens:256,top_p:1,frequency_penalty:0,presence_penalty:0代碼生成與實踐案例真實案例：GPT-4 輔助實現生產級完整模塊代碼https:/ 代碼生成與實踐

3、案例測試代碼生成，主要是單元測試代碼：代碼生成 GPT“編程”8條軍規1.bug難以避免，Chat，結對編程，反饋修改，而不是單向生成，多次結果比較2.起點也不一定是從一個自然語言需求出發，也可以是給他一段代碼參考并且簡單描述需要做的事情，或者從偽代碼轉成可以運行的代碼（典型任務：重構）3.讓GPT來寫單元測試！4.由于GPT的原理，溝通時間長了，它會“忘記”完整的上下文，需要不時幫他回顧5.目前即便是GPT-4尚缺少面向對象和架構能力，但是在人類的提示下，它可以幫忙完成類的封裝等架構改進，實現具體代碼6.Shell、SQL.go、rust.新的或者小眾框架預期不能太高7.必須由人 Revie

4、w GPT寫的代碼，拒絕“看不懂”的代碼進入系統8.保持一定的人工手寫代碼比例代碼審查與實踐案例 代碼段審查 合并請求審查GPT 比較偏向于發現代碼段的質量問題典型例子：1.字符串 or 枚舉2.if 嵌套太深的問題，或者不會被執行的分支 3.敏感信息泄露4.變量命名規范5.審核工作量降低 70+%局部問題導致的代碼質量問題減少 40+%核心程序員代碼貢獻量提高一倍以上Pull Request Review 案例https:/ 在src/provider/gpt_provider.ts文件中，API_KEY是硬編碼的字符串。建議使用環境變量或配置文件來安全地存儲API密鑰。https:/ “為
