Headers

​
X-Async-Mode
boolean
default:false

Enable async processing mode. When set to true, the request will be processed asynchronously and immediately return a task ID instead of waiting for the complete response.

Notes:

  • Async mode has the highest priority, even if streaming method is set, it will return a task ID
  • After receiving the task ID, use the task query API to get the generation result, which will always be in non-streaming format
