How to order
This is the image-to-image twin of qwen3-pro-text-to-image: create the series with that id in model and attach reference images — the service switches to this model by itself. Its own id is not accepted in a series.

boolean | optional | Whether to enable content filtering. Optional. Defaults to false. When set to false, content filtering is disabled and all results are returned directly by the model.
