</p>
<p style="font-size: 1rem; margin-bottom: 1.5rem;">Please light a star for the <a href='https://github.com/witcherofresearch/PromptRoute' target='_blank'>Code</a> if you find the demo useful, thank you.</p>
<p style="font-size: 1rem; margin-bottom: 1.5rem;">In this demo, we question whether there exist any conflicts when learning multi-ref subject-driven image generation and content-preserving style transfer given content ref and style ref with a unified model. The conclusion is no and our PromptRoute's solution is simple: we attach "Compose the pictures" for multi-ref subject generation, and "Style Transfer the style of Figure 2 to Figure 1, and keep the content and characteristics of Figure 1." for content-preserving style transfer during training and inference. Such simple prompts distinguish the tasks and eliminate the confusion. </p> 
<p style="font-size: 1rem; margin-bottom: 1.5rem;">Caution: If you choose infer with content/style prompt, pls do not forget to clean the prompt box when you run a new  inference. The results of multi-ref subject generation are all 16:9 in this demo. </p>
<p style="font-size: 1rem; margin-bottom: 1.5rem;">If you encounter an Error with this demo, the most possible reason is ZeroGPU out-of-memory and the solution is to decrease the Min Edge of the generated image from 1024 to a lower value.  </p>

	</p>
	<p style="font-size: 1rem; margin-bottom: 1.5rem;">Please light a star for the <a href='https://github.com/witcherofresearch/PromptRoute' target='_blank'>Code</a> if you find the demo useful, thank you.</p>

	<p style="font-size: 1rem; margin-bottom: 1.5rem;">In this demo, we question whether there exist any conflicts when learning multi-ref subject-driven image generation and content-preserving style transfer given content ref and style ref with a unified model. The conclusion is no and our PromptRoute's solution is simple: we attach "Compose the pictures" for multi-ref subject generation, and "Style Transfer the style of Figure 2 to Figure 1, and keep the content and characteristics of Figure 1." for content-preserving style transfer during training and inference. Such simple prompts distinguish the tasks and eliminate the confusion. </p>

	<p style="font-size: 1rem; margin-bottom: 1.5rem;">Caution: If you choose infer with content/style prompt, pls do not forget to clean the prompt box when you run a new inference. The results of multi-ref subject generation are all 16:9 in this demo. </p>

	<p style="font-size: 1rem; margin-bottom: 1.5rem;">If you encounter an Error with this demo, the most possible reason is ZeroGPU out-of-memory and the solution is to decrease the Min Edge of the generated image from 1024 to a lower value. </p>
