Short answer: you’re right — in Prefect 3.x there’s no

retry_jitter_factor

for flows. Flows support

retries

and a fixed `retry_delay_seconds`; jitter is only available on tasks. - Flow options:

@flow(retries=3, retry_delay_seconds=60)
  def my_flow():
      ...

Docs: Flow decorator - Task options (with jitter):

@task(
      retries=5,
      retry_delay_seconds=[5, 10, 20, 40, 80],
      retry_jitter_factor=0.2,
  )
  def my_task(...):
      ...

Docs: Task decorator Common workarounds if you need flow-level jitter: - Put the retry/jitter on the critical task(s) instead of the whole flow. - Build a “supervisory” parent flow that calls your real flow as a subflow and implements its own sleep-with-jitter between attempts. This won’t show as native flow retries in the UI (you’ll see multiple subflow runs instead), but it lets you control jitter timing.
