Inside Devin: The world’s first autonomous AI engineer that's set to write 50% of its company’s code by end of year | Scott Wu (CEO and co-founder of Cognition)
Lenny's Podcast: Product | Growth | Career
Revolutionizing Onboarding with AI
This chapter explores the innovative use of an AI assistant named Devin in enhancing the onboarding experience for new engineers. By automating tasks and providing insights into the codebase, Devin reduces dependency on human mentors while integrating seamlessly into workflows. The discussion also examines the balance between user preferences and the practical challenges faced in developing effective AI engineering solutions.
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
