# Concurrency limits

> How many jobs can run at once, and what happens at the cap.

GPU stages are scheduled fairly across accounts, so per-account in-flight
caps apply:

* **In-flight jobs per account**: template pages note any per-template caps
  (GPU-heavy stages like matting cap at **3 concurrent** per account).
* At the cap, new runs return the typed blocker `IN_FLIGHT` at estimate
  time, or HTTP 429 at run time. Back off and retry; don't tight-loop.
* Queue position and estimated wait are reported on the job while queued.

Higher limits for production workloads: contact us: the caps are policy,
not physics.
