Grok Agent Update: Background Tasks, Session Reattach and UI Improvements
elonmusk · x · 2026-08-06
xAI releases a new build update (v0.2.121) for the Grok agent. The update focuses on enhancing agent task execution and terminal experience: when a subagent runs in the background, the parent agent is now reminded to keep working on the original task. Clients can also reattach to running sessions without replaying the transcript.
Additional features include a short summary of previous turns on the dashboard, grouped and collapsible extensions modal, and proper auto theme detection over SSH and inside tmux sessions.
