How many tasks can run at the same time?
There's no fixed user-facing limit. Astra creates separate root Tasks for genuinely independent outcomes and routes each to Astra herself or the selected Team's Delivery Lead. Inside one Task, that Lead can run numbered child Tasks in parallel across specialists, harnesses, or models. You still talk only to Astra, so you do not have to manage those lanes.
What affects speed?
Deep research and complex builds take longer, but they share capacity efficiently. A quick content task and a long video task can run side by side without slowing each other down.
How do I check on progress?
Work shows a compact, read-only view of active Tasks. Ask Astra about any Task number for its latest evidence, remaining work, or overall capacity; child progress is summarized at the parent.
