A team of 'Devins' is already producing 25% of Cognition's pull requests, and they are on track to hit 50% by the end of the year.

Our engineering team of 15 uses about five Devins each to help them code and move faster, with Devins merging several hundred pull requests into production every month.

Each engineer on Cognition's 15-person engineering team works with about five Devins each, enhancing productivity and collaboration.

90% of the code for some products is now written by AI, leading to unexpected bottlenecks in other areas like the merge queue, which had to be completely rearchitected due to the increase in pull requests.

Stacking pull requests has led to meaningful improvements in development speed, with some customers reporting up to a 3x increase in speed and saving developers significant time each week.

Using deep research integration with GitHub, I can analyze pull requests, identify potential improvements, spot bugs, and suggest fixes in minutes.

Devin creates its own wiki to understand and document complex codebases, improving its ability to assist engineers effectively.

The concept of stacked pull requests allows developers to break changes into smaller, dependent updates, making code reviews more manageable and improving development speed significantly.

Visual Studio now has over 50 million users, and GitHub has 150 million users, with GitHub Copilot being used by more than 15 million developers.
