Scott Wu: 我是Cognition公司的联合创始人兼CEO,我们开发了全球首个自主式AI软件工程师Devin。Devin可以像远程工程师一样,通过Slack、Linear和GitHub与团队协作,完成端到端的软件开发任务。目前,Devin已经能够完成我们公司25%的代码编写工作,预计年底将达到50%。我们的团队只有15名工程师,每位工程师同时与5个Devin协作。Devin的能力在过去一年中得到了显著提升,从最初的‘高中CS学生水平’发展到现在的‘初级工程师水平’。我们相信,AI将是改变我们生活最大的技术变革,它将极大地提高软件开发效率,并导致软件工程师数量的增加,而非减少。未来,软件工程师的角色将从‘砌砖者’转变为‘建筑师’,更多地关注系统架构和问题定义,而AI将负责具体的代码实现。Devin的设计理念是将其视为一个可以自主完成任务的实体,工程师可以与其进行交互和协作。我们经历了多次迭代和转型,最终实现了AI工程师的成功应用。我们相信,AI将极大地改变软件工程的未来,并创造出更多价值。 Lenny Rachitsky: 作为一名播客主持人,我对Devin的开发和应用非常感兴趣。Devin的出现标志着AI技术在软件工程领域的重大突破,它能够像人类工程师一样与团队协作,提高开发效率。Devin的应用案例表明,AI能够显著提高软件开发效率,并改变工程师的工作方式。未来,工程师将更多地关注架构设计和系统思维,而具体的代码实现将更多地由AI完成。同时,AI工具的应用也需要考虑团队文化和工作流程的调整。

Scott Wu is the co-founder and CEO of Cognition, the company behind Devin—the world’s first autonomous AI software engineer. Unlike other AI coding tools, Devin works like an autonomous engineer that you can interact with through Slack, Linear, and GitHub, just like with a remote engineer. With Scott’s background in competitive programming and a previous AI-powered startup, Lunchclub, teaching AI to code has become his ultimate passion.What you’ll learn:

  1. How a team of “Devins” are already producing 25% of Cognition’s pull requests, and they are on track to hit 50% by year’s end

  2. How each engineer on Cognition’s 15-person engineering team works with about five Devins each

  3. How Devin has evolved from a “high school CS student” to a “junior engineer” over the past year

  4. Why engineering will shift from “bricklayers” to “architects”

  5. Why AI tools will lead to more engineering jobs rather than fewer

  6. How Devin creates its own wiki to understand and document complex codebases

  7. The eight pivots Cognition went through before landing on their current approach

  8. The cultural shifts required to successfully adopt AI engineers
