Qwen Image 3.0
[Core Function] Qwen Image 3.0 is Alibaba’s standard text-to-image model balancing quality and speed. [Strengths] It supports free-form output size (widthheight), optional negative prompts, intelligent prompt rewrite (direct/agent modes), batch generation of 1-6 images, and long structured prompts. [Best For] General creative stills, posters with readable text, product shots, and multi-variant exploration (n up to 6) when Pro-tier photorealism is not required. [Limitations] Do NOT use this if the user needs image editing with reference images (use Qwen Image 3.0 Edit). Keep total pixels within 512512 to 2048*2048. Very long prompts combined with a long negative_prompt may exceed the model input capacity (about 4.5k tokens total). [Routing] Prefer Qwen Image 3.0 Pro for higher photorealism; use this for balanced quality/speed. If the user provides reference image(s) to edit, route to Qwen Image 3.0 Edit instead.

Whether to enable intelligent prompt rewriting. Default true (recommended). When enabled, the model rewrites the positive prompt using the mode specified by prompt_extend_mode; most effective for short or simple prompts.
true
Prompt rewrite mode when prompt_extend is true. Default direct. direct: Direct Prompt Enhancement (DPE), suitable for most scenarios (T2I and I2I). agent: Agent Prompt Enhancement (APE), finer rewrite; text-to-image (T2I) only.
