Grok Build 1.0.9: Child-agent budgets and concurrent subagent improvements
eyishazyer · x · 2026-08-25
Grok Build 1.0.9 is out with key improvements for agent tasks. Workflows can now set child-agent budgets and reasoning effort. Agents can discover and launch workflows by name. Plugin-provided agents now appear in /agents and can be toggled. Concurrent subagents are much more resilient to rate limits, and running shell commands move to the background upon sending new messages.
