Safety and limits

What is checked before a job runs, what is not, and the limits that apply.

Moderation

  • Prompts are checked before the job is queued. A rejected prompt returns content_policy_violation and uses no GPU time.
  • Image, video, and audio inputs for fl2va and ref2va are higher risk, because they can be used for likeness manipulation. They are checked for unsafe content and for faces or likeness before the job is queued. These tasks are not to be enabled without that check.
  • Outputs are not scanned before delivery. That is a known gap. Depending on how you use the service you may need your own output review.

Limits

LimitValue
Clip length4 to 15 seconds per job.
Outputs per job1 to 10 (num_outputs_per_prompt).
Resolution768p on the short edge.
InputsURLs we fetch. Size and content-type limits are not final.
Rate limitingPer API key, using a sliding window. Numbers are not final.
Result retentionShort, then deleted. Window not final.

Rate limiting exists so that one key cannot take over the small, expensive pool of GPU workers and to limit the damage from a leaked key. Expect queued time under load.
