Request Limits
Request limits are jointly determined by the gateway, file service, model service, and billing system. This page describes only the stable constraints of the public API; actual limits are determined by server-side error codes.
Basic limits

| Audio output format | e.g. mp3 / wav; the exact supported range depends on the endpoint, mp3 recommended |
| Asynchronous task | Pass async=true to create a task; query with task_id |
