| ### Description | |
| OmniGen is a unified image generation model that you can use to perform various tasks, including but not limited to text-to-image generation, subject-driven generation, Identity-Preserving Generation, and image-conditioned generation. | |
| For multi-modal to image generation, you should pass a string as `prompt`, and a list of image paths as `input_images`. The placeholder in the prompt should be in the format of `<img><|image_*|></img>` (for the first image, the placeholder is <img><|image_1|></img>. for the second image, the the placeholder is <img><|image_2|></img>). | |
| For example, use an image of a woman to generate a new image: | |
| prompt = "A woman holds a bouquet of flowers and faces the camera. Thw woman is \<img\>\<|image_1|\>\</img\>." | |
| --- | |
| ### Tips | |
| For out of memory or time cost, you can refer to [./docs/inference.md#requiremented-resources](https://github.com/VectorSpaceLab/OmniGen/blob/main/docs/inference.md#requiremented-resources) to select a appropriate setting. | |
| ``` | |
| - If time cost is too long, please try to reduce the `max_input_image_size`. | |
| - Oversaturated: If the image appears oversaturated, please reduce the `guidance_scale`. | |
| - Not match the prompt: If the image does not match the prompt, please try to increase the `guidance_scale`. | |
| - Low-quality: More detailed prompt will lead to better results. | |
| - Animate Style: If the genereate images is in animate style, you can try to add `photo` to the prompt`. | |
| - Edit generated image. If you generate a image by omnigen and then want to edit it, you cannot use the same seed to edit this image. For example, use seed=0 to generate image, and should use seed=1 to edit this image. | |
| - For image editing tasks, we recommend placing the image before the editing instruction. For example, use `<img><|image_1|></img> remove suit`, rather than `remove suit <img><|image_1|></img>`. | |
| - For image editing task and controlnet task, we recommend to set the height and width of output image as the same as input image. For example, if you want to edit a 512x512 image, you should set the height and width of output image as 512x512. You also can set the `use_input_image_size_as_output` to automatically set the height and width of output image as the same as input image. | |
