Devin can now break tasks down and run a team of managed Devins

Devin can now break large tasks into scoped pieces and delegate them to a team of managed Devins that run in parallel.

Each managed Devin runs in its own isolated virtual machine with its own terminal, browser, and development environment, and has its own session link.

The main coordinator session monitors progress, resolves conflicts, and compiles results, and managed Devins are available now for all users.
