Qwen's Image 2.1 PE T2I expands a brief image request into a detailed English prompt and recommends an aspect ratio. According to its model card, it accepts requests in different languages and returns structured text that an application can pass to the main image model.
The integration example uses those two outputs separately: the rewritten description controls the requested content, while the recommended proportions determine image dimensions. This gives developers a prompt-preparation stage they can inspect and adjust before spending computation on rendering.
