Devin 3
Cognition's autonomous software engineering agent, now able to run unsupervised multi-day engineering sprints with persistent repo memory and automatic PR-review handling.
Overview
Cognition released Devin 3 on October 5, 2026, adding a 'sprint mode' that plans, codes, tests, and opens pull requests without supervision for up to 72 hours on a single ticket or migration. Devin 3 keeps persistent cross-session memory of a repository's architecture, prior review feedback, and team coding conventions, and automatically responds to human PR comments by pushing follow-up fixes rather than waiting for a new task to be assigned. It takes task intake from GitHub, Linear, and Slack Code.
