What changed
SWE-2 is listed under a Research preview section of the agent selector, with Medium, High or Max reasoning effort. You can pick it when starting a session, switch to it mid-session, or call it in Slack with !swe2. An enterprise admin must enable it first, and organisation admins can toggle it under Agent capabilities. Cognition warns its behaviour and availability may change during the preview.
Who it affects
Devin users and admins at enterprise and team organisations.
What to do
Have an admin enable the SWE-2 preview, and compare it with your current agent on low-stakes tasks first.
