They show where a task is, in Task History, on the dashboard and on model pages:
Queued: waiting for a free server, or just picked up by one. Waiting is free.
Running: Wiro prepares the inputs, runs the model and uploads the files. This includes
task_error, an error line reported along the way. It isn't a failure; the task can still succeed.Completed: the model reported success. It can show before the files finish uploading, so refresh after a few seconds.
Failed: the task finished, but the model reported an error (in the API, a
pexitother than"0"). Failed runs aren't charged, except realtime voice turns.Cancelled: stopped early, usually because you cancelled or killed it.
A task counts toward your concurrency limit until it's Completed or Failed with files uploaded, or Cancelled. Wiro Studio shows raw status names instead, in red for failed or cancelled runs.
