Devin

Devin is an autonomous AI software engineer developed by Cognition. It is designed to handle entire software development tasks, from understanding the initial request to delivering a ready-to-merge pull request. Devin can run in the cloud or on a local machine, and it uses its own browser for testing. It aims to complete tasks without human intervention until the code is ready for review and integration.

The tool can perform various engineering tasks, such as adding new features, fixing bugs, or conducting security scans. It operates by spinning up virtual machines (Windows, Mac, Linux) as needed to build and test code. Devin can also record its actions, showing how it interacts with the software it builds. It integrates with existing workflows, allowing users to delegate tasks and receive updates. Devin can also be tagged in communication platforms like Slack or Teams to respond to issues and initiate fixes.

Devin leverages multiple frontier AI models, combining them to optimize performance and cost efficiency. It can proactively watch for issues and fix them, for example, by responding to PagerDuty alerts or addressing failed CI builds. The tool is designed to understand and plan complex engineering work, mapping codebases and system architectures, and updating documentation as changes occur.
