Grok Build can fan one job across up to 1,024 agents. The review problem grows with the swarm.
Grok Build can now create background workflows that split a large coding task across many agents, verify the pieces and return a combined report.

Bit’s takeaway
What changed
xAI added Workflows to Grok Build. A workflow can plan a large task as phases, run on a default budget of 128 background agents that can grow to 1,024 for big jobs, verify findings and synthesise the result while the main session remains available.
Why it matters
Parallel agents can reduce elapsed time on work that genuinely decomposes, but they also multiply assumptions, duplicated effort and places where a weak finding can enter the final synthesis. More agents do not remove the need for one accountable review standard.
Who should care
- Engineering teams reviewing large repositories or pull requests
- People designing multi-agent coding and research workflows
What to do
Keep this for a task with cleanly separable work streams. Define one shared acceptance test, require evidence from every branch and compare the swarm with a smaller controlled baseline before adopting it.
The human take
Tools change fast. Your judgment matters more.
One person or team still owns the shared acceptance standard and the decision to trust the combined result.
